REPOST: Get wise about your eyes

Too much use of cosmetics, stress, staying up late at night are some of the  factors that can lead to vision problems. This Health.com article shares some ways on how to keep the  eyes healthy.

We never appreciate how much our eyes do for us—from helping to navigate the world to letting us ogle George Clooney—until something goes wrong. In fact, they're more sensitive than you think: Your eyes are affected by everything from makeup to air-conditioning to all those birthdays. Here's how to take care of them so you can keep seeing the sights.

'My eyes are always itchy this time of year' 

Seasonal allergies can make your eyes itch like crazy, thanks to the histamine they (and other body parts) produce in response to pollen and other irritants.

How to see clearly: Staying indoors with the windows shut is ideal, but we know you can't be a total recluse. So use over-the-counter allergy eyedrops such as Naphcon-A, or ask your doc to prescribe a more potent one such as Pataday, says Anne Sumers, MD, a clinical correspondent for the American Academy of Ophthalmology. And shower before bed so pollen's not lingering on your face and in your hair all night long.

'Why are my lids pink and puffy?' 

If one or both of your eyelids are inflamed, itchy, and red, you may have blepharitis, which occurs when bacteria or excessive oil from your eyes coats the lid near the eyelash line. It can also be caused by allergies. "Blepharitis, which is not contagious and usually doesn't require antibiotics, often gets mistaken for pink eye, which is usually caused by a virus and is highly infectious," Dr. Sumers says. Check in with an eye doctor to figure out which one you've got. A pink eyelid can also mean you have a sty, a bacterial infection on your lid that takes the form of a painful, pus-filled pimple.

How to see clearly: Prevent and treat both styes and blepharitis by keeping the eye clean. Soak a washcloth with warm water, wring it out, and place it over your closed eye for a minute or two. Do this two or three times a day. "Clean all your eye makeup off every night," Dr. Sumers adds, "and never wear eyeliner inside your lash line." And no matter how tempted you are, don't pop a sty, or you could spread the infection.

'My eyes are burning!' 

If you feel a gritty, scratchy, or even stabbing pain in your eyes, you may be one of the 10 million Americans suffering from dry eye syndrome. Blame modern life: Air-conditioning and central heating can leave eyes parched, says Stephanie Marioneaux, MD, an ophthalmologist in Chesapeake, Virginia. Plus, studies have shown that when we stare at a screen, we don't blink as often, so our eyes lose their natural lubrication. If you wear contact lenses, you're more prone; same goes if you smoke or take medications such as antihistamines or decongestants.

How to see clearly: Try artificial tears. "Gels that are labeled 'for severe dry eye,' such as Systane, are thicker and last longer, but they can feel gummy and blur vision," Dr. Sumers says. "Drops that are labeled 'mild to moderate,' such as Refresh, are thinner and feel better, but won't last as long."

If drops don't do the trick, your doctor can prescribe a topical medication or fit you with punctal plugs (they're inserted into your eye to keep tears from draining too quickly). Use a vaporizer or humidifier to keep indoor air moist, too. Surprisingly, eating fish high in omega-3 fatty acids—such as salmon, sardines, and tuna—may reduce your risk of dry eye, and taking flaxseed oil and omega-3 supplements may relieve symptoms, studies suggest. And every 10 minutes or so, look away from your computer or tablet screen and bat your lids like Scarlett O'Hara.

'Menus are suddenly hard to read'

No matter how great your vision's been, it's nearly inevitable that you'll have more trouble seeing things close up as you reach your 40s. The lens in your eye gets harder and less flexible over time, gradually losing the ability to focus, Dr. Marioneaux explains. The retina also becomes less light-sensitive, so it's harder to see in dim light.

How to see clearly: Squinting as you read? Pick up a pair of +1 glasses at the drugstore. (Wearing glasses won't make your sight worse—that's just a myth, Dr. Sumers says.)

If you already have glasses or contacts for distance and don't want to switch between two pairs, go for old-fashioned bifocals (or newer bifocal contact lenses), trifocals (which have a third zone in the middle for computer-distance vision), or progressive lenses (which blend the edges so you can see everything from a movie screen to a medicine label without as much distortion). Another option is monovision, in which your dominant eye is corrected (with contacts or surgery) for distance, and your other eye is corrected for close-up vision.

Let your gadgets work for you, too: Increase the font size on your e-reader, for instance, or try apps such as MagLight, which turns your smartphone into a light-up magnifying glass.

'I keep seeing spots'

Little dots and squiggly lines, called "floaters," come into your field of vision when the vitreous humor—a gel-like part of the eye—begins to shrink, causing cells and fibers to clump and cast shadows onto your retina. In most cases, they're harmless, but if a whole bunch appear suddenly, or if they're accompanied by persistent flashing lights or peripheral-vision loss, see your eye doctor ASAP—both could be signs of a retinal tear or detachment.

How to see clearly: If you've got a retinal detachment, or the floaters are so bad they're impairing your vision, you'll need surgery. Otherwise, most folks just learn to live with them, and even ignore them

Contact lenses now, corneal abrasions later

Apart from being fashion staples, contact lenses have been accepted by ophthalmologists and eye patients alike as a viable alternative to eye glasses. As a matter of fact, more patients are beginning to prefer contact lenses over glasses and as of 2011, there were approximately 36 million Americans using contact lenses to compensate for refractive errors.

Image Source: ezyvision.com.au

While advantageous in a myriad of ways, contact lenses are not without some downsides. One of the greatest problems that contact lens users may have to contend with is the risk for corneal abrasions.

Cornea: The eye’s fine window

The cornea is “a transparent, dome-shaped window covering the front of the eye.” It is an important anatomical structure which makes for a powerful refracting surface, and provides approximately 2/3 of the eye’s focusing power.

Image Source: images.search.yahoo.com

Inasmuch as it is the eye’s frontline protective structure, it is as fragile as any mucosal membrane; perhaps more so, owing to its fineness. This is why even the tiniest particles like dirt, dust, sand, and wood shaving can superficially scratch the cornea, resulting to abrasions.

This condition may be worse for contact lens wearers. A 2004 study by Quinn and Kwartz stated that “contact lenses can compromise the corneal epithelium,” making it more susceptible to cuts and tears. To make matters worse, contact lenses can also act as “pathogenic vectors,” and may take part in facilitating the development of bacterial keratitis. Quinn and Kwartz observed that contact lens wearers may be at risk for a rapid-progression corneal scarring, and if worst comes to worst, corneal perforation.

The rise in contact lens use is largely due to its convenience, but because of its accompanying risks, users are reminded to observe commensurate care, as corneal abrasions may be a hefty price to pay for even a measly lack of caution in usage.

REPOST: What’s best for kids’ eye health? Experts give insight

This article by Serena Gordon gives valuable insights on proper eye care for children.

Image Source: news.health.com

WEDNESDAY, Dec. 26 (HealthDay News) — For generations, countless adults have urged kids to eat carrots to protect their eyesight.

“Anything that’s good for your body is good for your eyes, especially vegetables,” explained Dr. James McDonnell, a professor of ophthalmology and director of pediatric ophthalmology at the Loyola University Health System and the Stritch School of Medicine in Chicago.

But how does the average adult, without medical training, know whether the words of wisdom being doled out — whether about crunching carrots or anything else — are good advice? And what else do parents need to know to keep their kids’ vision keen?

Here’s a sampling of advice from eye experts:

How often should children have their eyes screened for vision problems?

Generally, kids don’t need any additional eye exams. Schools and pediatricians screen for eye problems and should flag any eye issues that warrant a visit to an eye specialist.

“The process is set up to screen all children for the most common eye problems,” said Dr. Erin Stahl, an ophthalmologist at Children’s Mercy Hospitals and Clinics in Kansas City, Mo. But, she did recommend that “parents should make sure that these screenings are being done yearly.”

But, if children complain of eye pain or say that they’re having trouble seeing, take them to an eye specialist, she said. The same is true if you notice that your child’s eyes don’t seem to be aligning properly.

Children don’t always wear their glasses. Can this be harmful?

McDonnell said the answer to this question can depend on the reason the glasses were prescribed. But, in general, if an eye doctor has prescribed glasses for a child, there’s probably a good reason that he or she needs to wear them.

“Most of the time, I put kids in glasses because without them their eyes cross,” McDonnell said. “The glasses help their brains develop properly at the critical age that lets eyes work together. In other kids, I might prescribe glasses because one eye is out of focus. These kids need to wear their glasses so that their brain isn’t only receiving blurry input from that eye.”

If you’re having trouble getting a child to wear his or her glasses regularly, Stahl added, ask the doctor whether off-and-on wear will cause any problems.

Pre-teens sometimes want to wear contacts. Is it too soon?

Both McDonnell and Stahl said that the age at which contacts are appropriate depends largely on a child’s maturity level.

For the most part, Stahl said, she won’t prescribe contacts to anyone younger than 10. McDonnell said he usually doesn’t consider contacts until a child 12 to 15 years old. Any child has to be mature enough to put contacts in, take them out and keep them clean, he noted. But even then, he added, parents still need to check to be sure their children are following the proper contact care techniques.

That includes making sure they’re not sleeping with their contacts in — something McDonnell said that children should never do. Eye experts agree that sleeping in contacts increases the chance of infection.

Are decorative contacts OK?

Decorative or cosmetic contacts are lenses that kids (and adults) sometimes wear, perhaps as part of a costume, to dramatically change their eye color or make their eyes look like those of a cat or a zombie. In the United States, it’s illegal to sell decorative lenses over-the-counter, meaning that they require a prescription, even if the youngster who wants them doesn’t need lenses for vision correction.

McDonnell said that if kids are familiar with contact wear and care, and they know how to keep them clean, he doesn’t see a problem with wearing decorative contacts for a special occasion. But if it takes an adult to help a child put decorative contacts in or take them out, that should be a sign that this is a bad idea. Stahl added that she’s seen severe eye injuries from cosmetic contacts.

Will too much computer time hurt a child’s eyes?

“Too much screen time will not damage a child’s eyes,” said Stahl. That said, “too much screen time is not good for the overall development of the child,” she added.

At worst, said McDonnell, spending a lot of time in front of a screen might cause eye strain. “It’s like doing push-ups for three hours,” he said. “Give your eyes a break and look up from that near point and gaze around the room from time to time.”

What should be done to protect a child’s eyes from injuries?

McDonnell said that it’s hard to anticipate everything that could hurt a child’s eyes because even something as seemingly innocuous as a child’s fingernail can cause a serious injury. Still, he said, it’s important to try to prevent eye injuries.

“If something penetrates the eye, these can be devastating injuries,” he said. “We do our best to repair the eye, but it’s part of the brain, which makes it exquisitely sensitive, even though it’s reasonably tough.”

For starters, Stahl said, “keep your child away from fireworks, lawn mowers and trimmers, and sharp objects like sticks and hangers.” She and McDonnell both recommended that kids wear eye protection during certain sports, especially those that involve smaller balls, such as racquetball or squash. McDonnell also advised that children not be allowed to play with BB or pellet guns because of the risk for eye and other injuries.

Intacs: An alternative to laser eye surgery

Image Source: mmkliinik.eu

Good eyesight is an important part of a person’s well-being and a significant factor in retaining independence and quality of life. Many who are afflicted with eye problems resort to surgical procedures while others prefer wearing corrective glasses and contact lenses. If you are thinking about undergoing LASIK surgery to correct your vision, there is another option that you must strongly consider before making the final decision.

Intacs corneal implants are micro-thin rings an ophthalmologist inserts in the cornea to rectify eyesight. They are usually used to provide clear maintenance-free vision for those who are near-sighted or are suffering from myopia. Intacs, once inserted in the eye, gently reshape the curvature of the cornea from within. By slightly adjusting the shape of the cornea, light rays can pass properly through the retina, providing nearsighted people with clear and precise vision.

Compared to the popular laser eye surgery, Intacs is more flexible. Laser surgeries reshape the cornea by permanently removing tissue from the central optic zone. When a patient needs to adjust their vision, additional tissue must be removed. Meanwhile, Intacs do not require removal of tissue. If vision adjustments are required, Intacts can be replaced with a different size to meet the changes needed. Corneal implants can also be removed if necessary, giving the patients the security they need with a permanent refractive procedure.

Inserting Intacs into the eye must be administered by qualified ophthalmologists such as Dr. Hitesh K. Patel and Dr. Barry Schanzer, both practicing in Edison, NJ.

Straightening perspectives: Seeing through strabismus

You might have wondered at some point why there are some people whose eyes seem to be abnormally positioned. Some of them might have eyes that don’t look straight ahead, while others have eyes that dart into different directions when they’re supposed to be focusing on a single object.

Chances are that those people might be suffering from strabismus.

Image credit: cecraleigh.com

Strabismus is a condition where the eyes are not straight and do not seem to focus on the same object. The abnormality may come in different forms. Sometimes, eyes can turn in (converging toward the nasal bridge) or out (diverging toward the ears). The condition is caused by the failure of the eye muscles to move accordingly or the inability of the eyes to focus properly. To date, about 4 out of 100 American children are affected by this condition.

Ophthalmologists, such as Dr. Hitesh Patel of Edison, NJ and Dr. Brian Campolattaro of Clifton, NJ, usually diagnose strabismus during infancy or early childhood. If a kid is found with the condition, the doctor may discuss with the parents regarding the available treatment modalities that are applicable to the child. In some cases, children may just be prescribed with corrective glasses. In more advanced cases, however, surgery is necessitated to correct the misalignment. Kids who have developed ‘amblyopia’ may need to wear a patch over their good eye to build up the weaker one.

It is important to note, however, that promptness of treatment is of key importance in successful case management. Doing so will ensure that kids will grow up with optimal vision—free from the needless psychological repercussions resulting from the social stigma that come with the condition.

Dietary health and age-related macular degeneration

Early or intermediate stages of age-related macular degeneration (AMD) account for the leading cause of severe vision loss in people over 50. However, when dietary health is concerned, there’s something that the elderly can do to help reduce the risk of progression, as PubMed.gov asserts.

Image credit: pdazzler.net

While some certain types of fat intake and some fat-containing food groups modified the risk of the progression of AMD, fish intake and nuts reduced risks. Moreover, this NY Times article reports that having a diet rich in leafy vegetables, nuts, and fish and has less carbohydrates reduces the risk for developing age-related macular degeneration. The dietary nutrients notable to be linked with lower risk for macular degeneration are Vitamins C and E, zinc, and some omega-3 fatty acids.

Edison-based eye doctors like Dr. Hitesh K. Patel, Dr. Stephen J. Gordon, and Dr. Dennis L. Blondo would agree that the eyes can benefit from protective nutrients generally found in fruits, green vegetables, nuts, and cold-water fish. Citrus fruits are good sources of Vitamin C, and leafy vegetables, beans, and nuts provide Vitamin E. Additionally, food sources like beans, nuts, and whole grains have zinc, and fatty fish like salmon is a good dietary source of the omega-3 fatty acids DHA and EPA.

Dry Eye Syndrome

Do your eyes feel dry and itchy, coupled with a burning sensation? Learn about syndrome you could probably be suffering from by reading thisAllAboutVision article.


Dry eye syndrome is a chronic lack of sufficient lubrication and moisture on the surface of the eye.

Its consequences range from subtle but constant irritation to ocular inflammation of the anterior (front) tissues of the eye.

Dry eyes also are described by the medical term, keratitis sicca, which generally means decreased quality or quantity of tears. Keratoconjunctivitis sicca refers to eye dryness affecting the cornea and conjunctiva.

Dry Eye Syndrome Symptoms Persistent dryness, scratchiness and a burning sensation in your eyes are symptoms of dry eyes. These symptoms alone may prompt your eye doctor to diagnose dry eye syndrome.

But sometimes your eye doctor may want to measure the amount of tears in your eyes. A thin strip of filter paper placed under the lower eyelid, called a Schirmer test, is one way to measure tear production.

Another symptom of dry eyes is a "foreign body sensation," the feeling that something is in the eye.

And it may seem odd, but dry eye syndrome can cause watery eyes. This is because dryness on the eye's surface sometimes will overstimulate production of the watery component of your tears as a protective mechanism.

What Causes Dry Eyes?

Tears bathe the eye, washing out dust and debris and keeping the eye moist. They also contain enzymes that neutralize the microorganisms that colonize the eye. Tears are essential for good eye health.

In dry eye syndrome, the lacrimal gland or associated glands near the eye don't produce enough tears, or the tears have a chemical composition that causes them to evaporate too quickly.

Dry eye syndrome has several causes. It occurs as a part of the natural aging process, especially during menopause; as a side effect of many medications, such as antihistamines, antidepressants, certain blood pressure medicines, Parkinson's medications and birth control pills; or because you live in a dry, dusty or windy climate.

If your home or office has air conditioning or a dry heating system, that too can dry out your eyes. Another cause is insufficient blinking, such as when you're staring at a computer screen all day.

Dry eyes also are a symptom of systemic diseases such as lupus, rheumatoid arthritis, ocular rosacea or Sjogren's syndrome (a triad of dry eyes, dry mouth and rheumatoid arthritis or lupus).

Long-term contact lens wear is another cause; in fact, dry eyes are the most common complaint among contact lens wearers.

Recent research indicates that contact lens wear and dry eyes can be a vicious cycle. Dry eye syndrome makes contact lenses feel uncomfortable, and evaporation of moisture from contact lenses worsens dry eye symptoms.

Incomplete closure of the eyelids, eyelid disease and a deficiency of the tear-producing glands are other causes.

Tears are composed of three layers:

• the outer, oily lipid layer;

• the middle, watery, lacrimal layer;

• and the inner, mucous or mucin layer.

Each layer is produced by different glands near the eye. The lacrimal gland located above the outer corner of the eye produces the lacrimal layer, for example. So a problem with any of those sources can result in dry eyes.

Dry eye syndrome is more common in women, possibly due to hormone fluctuations. A recent study also indicates that the risk of dry eyes among men increases with age.

Recent research suggests that smoking, too, can increase your risk of dry eye syndrome.

With increased popularity of cosmetic eyelid surgery (blepharoplasty) for improved appearance, dry eye complaints now occasionally are associated with incomplete closure of eyelids following such a procedure.

How Common Are Dry Eyes?

Dry eyes and dry eye symptoms are very common, particularly among older adults. And a recent consumer survey commissioned by Allergan suggests dry eyes are even more prevalent than previously believed.

The survey found:

• 48 percent of adult Americans regularly experience dry eye symptoms.

• 42 percent of women age 45 to 54 who have dry eye symptoms report blurred vision associated with the condition.

• Women more frequently than men report having difficulty using a computer due to dry eye symptoms (62 vs. 44 percent).

• 43 percent of adults with dry eye symptoms say they experience difficulty reading due to their symptoms.

• Among adults age 55 and older, 30 percent of men and 19 percent of women say they have experienced dry eye symptoms for more than 10 years.

• 19 percent of adults say they use over-the-counter eye drops at least five times per week to treat dry eye symptoms.

• 63 percent of adults who use non-prescription eye drops to treat dry eyes say the drops are not effective or only somewhat effective in managing their symptoms.

The survey also found that though dry eyes cause problems for nearly half of adult Americans, many people fail to seek professional help for dry eye symptoms: 69 percent of respondents who experience symptoms said they had not visited an eye care professional for dry eye treatment.

The Allergan Dry Eye Survey was conducted online in March 2011 by Harris Interactive, with 2,411 adults (age 18 and older) responding.

Treatment for Dry Eyes

Dry eye syndrome is an ongoing condition that may not be completely curable (depending on the cause). But the accompanying dryness, scratchiness and burning can be managed. Your eye care practitioner may prescribe artificial tears, which are lubricating eye drops that may alleviate the dry, scratchy feeling.

Prescription eye drops called Restasis (Allergan) go one step further: they help your body produce more tears by reducing inflammation associated with dry eye syndrome.

Another option for dry eye treatment is called Lacrisert, a tiny insert filled with a lubricating ingredient (hydroxypropyl cellulose). The insert is placed just inside the lower eyelid, where it continuously releases lubrication for the eye throughout the day.

Sometimes people use eye drops that are advertised to "get the red out" to treat their dry eyes. While these drops can reduce or eliminate eye redness temporarily, they may or may not be effective at lubricating your eyes, depending on the formulation.

Not only that, but your eyes can develop a tolerance to the eye whitening agents (vasoconstrictors) in these drops, which can cause even more redness over time. Redness-relieving eye drops can cause other adverse effects as well, especially if you use them too often.

If you wear contact lenses, be aware that many eye drops, especially artificial tears, cannot be used while your contacts are in your eyes. You'll need to remove them before using drops and wait 15 minutes or even longer (check the label) before reinserting the lenses.


If your eye dryness is mild, then contact lens rewetting drops may be sufficient to make your eyes feel better, but the effect usually is only temporary.

Check the label, but better yet, check with your optometrist or ophthalmologist before buying any over-the-counter eye drops. It will probably save you a lot of money, because he or she will know which formulas are effective and long-lasting and which ones are not, as well as which eye drops will work with your contact lenses.

If the problem is environmental, wear sunglasses when outdoors to reduce exposure to sun, wind and dust. You may want to try the kind that has a foam or other seal at the sides and/or a close-fitting, wrap-style frame to keep wind and dust from getting behind the lenses and in your eyes.

Recent research suggests that cold temperatures may be another environmental cause of dry eyes. If it gets cold and windy where you live, try wearing goggles when you're outside in winter.

Indoors, an air cleaner can filter out dust and other particles from the air, while a humidifier adds moisture to air that's too dry because of air conditioning or heating.

Temporary or permanent silicone plugs can be inserted in the lacrimal (tear) drainage ducts in your eyelids to keep tears on your eye from draining away as quickly. Called lacrimal plugs or punctal plugs, they can be inserted painlessly while you're in the eye doctor's office and normally are not felt once inserted.

A new type of punctal plug made of acrylic is a small rod that becomes a soft gel when exposed to your body heat after insertion. It is designed to swell and conform to the size of your tear drainage canal. Advantages of this type of plug are that one size fits all, so measurement is unnecessary, and nothing protrudes from the tear duct that could potentially cause irritation.

Another new kind of punctal plug is made of a hydrogel that expands into a soft, pliable gel in the tear drainage canal. It has no cap, and should it need to be removed, the eye care practitioner can simply flush it out with saline solution.

With some people, however, punctal plugs aren't effective enough, so their tear ducts need to be closed surgically (punctal cautery).

Doctors sometimes recommend special nutritional supplements for dry eyes. Studies have found that supplements containing omega-3 fatty acids can decrease dry eye symptoms.

Good sources of omega-3s include cold-water fish, such as sardines, cod, herring and salmon. Some eye doctors also recommend flaxseed oil to relieve dry eye.

Drinking more water can help, too. Mild dehydration often makes dry eye problems worse. This is especially true during hot, dry and windy weather. Simply drinking more water sometimes reduces the symptoms of dry eye syndrome.

The Institute of Medicine recommends that each day, women need 91 ounces of water and men need about 125 ounces. Experts agree that about 20 percent of the water your body needs comes from the food you eat, while the rest originates from the fluids you drink.

The best choices for beverages are water, 100 percent fruit and vegetable juices and milk.

If medications are the cause of dry eyes, discontinuing the drug generally resolves the problem. But in this case, the benefits of the drug must be weighed against the side effect of dry eyes. Sometimes switching to a different type of medication alleviates the dry eye symptoms while keeping the needed treatment. In any case, never switch or discontinue your medications without consulting with your doctor first!

Treating any underlying eyelid disease, such as blepharitis, helps as well. This may call for antibiotic or steroid eye drops plus frequent eyelid scrubs with an antibacterial shampoo.

If contact lens discomfort is the cause of your dry eyes, your eye care practitioner may want to switch you to a different lens or have you wear your lenses for fewer hours each day. In some cases, it is recommended that contact lens wear be discontinued altogether until the dry eye problem is cleared up.

Dry eyes and LASIK may not be a good combination. If you are considering LASIK, be aware that dry eyes may disqualify you for the surgery, at least until the problem is resolved.

Dry eyes increase your risk for poor healing after LASIK, so most surgeons will want to treat the dry eyes first, to ensure a good LASIK outcome. This goes for other types of vision correction surgery, as well.
