Controlling Nearsightedness in Children

Myopia (nearsightedness) is a common vision problem affecting children who can see well up close, while distant objects are blurred. Nearsighted children tend to squint to see distant objects such as the board at school. They also tend to sit closer to the television to see it more clearly.

Sometimes, childhood myopia can worsen year after year. This change can be disconcerting to both children and their parents, prompting the question: “Will it ever stop? Or, will this get so bad that, someday, glasses won’t help?”

Myopia that develops in childhood nearly always stabilizes by age 20. But by then, some kids have become very nearsighted, leading scientists to search for ways to slow down the progression of myopia in children. Four possible treatments that show promise include orthokeratology (“ortho-k”), atropine eye drops, multifocal eyeglasses, and soft multifocal contact lenses.

Orthokeratology

Orthokeratology, or “ortho-k,” is the use of specially designed gas permeable contact lenses to flatten the shape of the cornea and thereby reduce or correct mild to moderate amounts of nearsightedness. The lenses are worn during sleep and removed in the morning. Though temporary eyeglasses may be required during the early stages of ortho-k, many people with low to moderate amounts of myopia can see well without glasses or contact lenses during the day after wearing the corneal reshaping lenses at night.

Recent research suggests ortho-k may also reduce the lengthening of the eye itself, indicating that wearing ortho-k lenses during childhood may actually cause a permanent reduction in myopia, even if the lenses are discontinued in adulthood.

Atropine

Topical atropine is a medicine used to dilate the pupil and temporarily paralyze accommodation and completely relax the eyes’ focusing mechanism. Because research has suggested nearsightedness in children may be linked to focusing fatigue, investigators have looked into using atropine to disable the eye’s focusing mechanism to control myopia.

The results of these studies have been impressive. However, additional research has shown that the myopia control effect from atropine does not continue after the first year of treatment, and that short-term use of atropine may not control nearsightedness significantly in the long run.

Multifocal Eyeglasses

Some evidence suggests wearing eyeglasses with bifocal or progressive multifocal lenses may slow the progression of nearsightedness in some children. The mechanism here appears to be that the added magnifying power in these lenses reduces focusing fatigue during reading and other close work, a problem that may contribute to increasing myopia.

A five-year study published in Investigative Ophthalmology & Visual Science produced an interesting result involving nearsighted children whose mother and father were also nearsighted. These children, who wore eyeglasses with progressive multifocal lenses during the course of the study, had less progression of their myopia than similar children who wore eyeglasses with regular, single vision lenses.

Soft Multifocal Contact Lenses

New research shows that multifocal contact lenses also may be an effective myopia control treatment, potentially more so than multifocal eyeglasses. A recent study by researchers at Ohio State University found that wearing multifocal contact lenses reduces the rate of progression of myopia in children by 50%.

One potential reason why multifocal contact lenses may limit progression is that these lenses appear to reduce the lengthening of the eye, which leads to increasing myopia over time.

Are Contact Lenses a Good Choice for Kids?

Contact lenses can offer several benefits over other forms of vision correction for kids. But a common question many parents have is: “When is my child old enough to wear contact lenses?”

Physically, your child’s eyes can tolerate contact lenses at a very young age. In fact, some babies are fitted with contact lenses due to eye conditions present at birth. And in a recent study that involved fitting nearsighted children ages 8-11 with one-day disposable contact lenses, 90% had no trouble applying or removing the contacts without assistance from their parents.

A Matter of Maturity

The important question to ask yourself is whether your child is mature enough to insert, remove and take care of their contact lenses. How they handle other responsibilities at home will give you a clue. If your child has poor grooming habits and needs frequent reminders to perform everyday chores, they may not be ready for the responsibility of wearing and caring for contact lenses. But if they are conscientious and handle these things well, they may be excellent candidates for contact lens wear, regardless of their age.

Contact Lenses for Sports

Many kids are active in sports. Contact lenses offer several advantages over glasses for these activities. Contacts don’t fog up, get streaked with perspiration or get knocked off like glasses can. They also provide better peripheral vision than glasses, which is important for nearly every sport. There are even contact lenses with special tints to help your child see the ball easier.

For sports, soft contact lenses are usually the best choice. They are larger and fit closer to the eye than rigid gas permeable (GP) lenses, so there’s virtually no chance they will dislodge or get knocked off during competition.

Controlling Nearsightedness

If your young son or daughter is nearsighted, rigid gas permeable (GP) contacts may be a good choice. GP lenses are more durable and often provide sharper vision than soft contacts.

A modified technique of fitting gas permeable lenses — called orthokeratology or “ortho-k” — can reverse myopia temporarily. Kids put their ortho-K lenses in at night and wear them while they’re sleeping. In the morning, when the lenses are removed, nearsighted kids should be able to see clearly without lenses of any kind.

Researchers also are finding that multifocal soft contact lenses may be effective for myopia control. Multifocal contacts are special lenses that have different powers in different zones of the lens.

Building Self-Esteem with Contact Lenses

Contact lenses can do wonders for some children’s self-esteem. Many kids don’t like the way they look in glasses and become overly self-conscious about their appearance because of them. Wearing contact lenses can often elevate how they feel about themselves and improve their self-confidence. Sometimes, even school performance and participation in social activities improve after kids switch to contact lenses.

Glasses Are Still Required

If your child chooses to wear contact lenses, they still need an up-to-date pair of eyeglasses. Contact lenses worn on a daily basis should be removed at least an hour before bedtime to allow the eyes to breathe. Also, there will be times when your child may want to wear their glasses instead of contact lenses. And contact lenses should be removed immediately anytime they cause discomfort or eye redness.

Don’t Push Contacts on Your Kids

Motivation is often the most important factor in determining whether your son or daughter will be a successful contact lens wearer. If you wear contact lenses yourself and love them, that still doesn’t mean they are the right choice for your child. Some children like wearing glasses and have no desire to wear contact lenses.

Sometimes it’s just a matter of timing. Often, a child may feel they don’t want contacts, but a year or two later, they do.

Top Safety Tips for Contact Lens Wearers

Is it safe to reuse contact lens solution — and should you wear your lenses in the shower? Here are the answers to some common questions about contacts, and a few tips to keep your eyes in good shape.

Millions of people wear contact lenses as a convenient way to correct their vision. But all contact lens wearers must be vigilant about one thing — contact lens safety.

“Contact lenses are one of the safest medical devices when worn responsibly,” says Thomas L. Steinemann, MD, a professor of ophthalmology at Case Western Reserve University in Cleveland and a spokesperson for the American Academy of Ophthalmology. While contact lens use is safe, not caring for contact lenses properly or failing to follow contact lens safety rules can lead to serious problems. “Contact lenses can be a potential point for infection,” says Dr. Steinemann. “No matter how careful you are, germs are on our hands, eyelids, everywhere. When germs such as bacteria and fungi are on the contact lens, they can invade the eye.”

8 Important Precautions for all Contact Lens Wearers

If you wear contact lenses, here’s what you should know:

  • Get a contact lens prescription from an eye doctor. “Have your lenses fitted by a qualified eye care professional,” says Steinemann. Also be sure to get instruction on proper lens care.
  • Don’t wear contact lenses overnight. “When you close your eyes with your lenses in place, you’re reducing oxygen,” says Steinemann. “The surface of the eye becomes more vulnerable to infection. Also, you have a lens being closed against the eye — any germs on the lens are being slammed against the cornea.”
  • Don’t wear your contact lenses in the shower or while swimming.Lakes, rivers, sea water, swimming pools, and even tap water can all harbor an organism called acanthamoeba, which can cause eye infection. Wearing contact lenses while swimming, showering, or doing other water-related activities can lead to serious acanthamoebainfections of the eye.
  • Don’t reuse contact lens solution. “You may think you’re saving money by doing so, but the disinfecting capability of the solution is gone,” says Steinemann. Use fresh solution every time you store your lenses in their case.
  • Don’t use saline solution for contact lens cleaning or disinfection.Saline solution is simply sterile salt water. It will not clean or disinfect. Be sure to choose a solution that includes disinfectant.
  • Replace your contact lens case every two to three months. “Lens cases get dirty, just like a toothbrush,” says Steinemann.
  • Take out your contacts if they are bothering you. It seems like common sense, but it can be easy to ignore irritation when you’re busy or distracted. Never put up with irritation, as it could be sign of an infection or other problem.
  • Never use saliva as a wetting agent. “Your mouth is one of the dirtiest places in your body,” says Steinemann.

3 Steps to Follow When Handling Your Contacts

  • Before handling your contact lenses: wash your hands with soap and water and dry with a lint-free towel.
  • To remove lenses: After you take out each contact lens from your eyes, gently rub with solution. Then rinse each lens with fresh solution before storing them for disinfection; be sure you squeeze enough solution into each case compartment to cover each lens. Even if the packaging of the solution you use reads “no rub,” you should still clean each lens to remove any germs, says Steinemann.
  • To put in lenses: After disinfecting your contact lenses according to the product directions on your solution bottle and before you put them back in your eyes, rinse off each contact lens with fresh solution. Discard used solution, rinse out the lens case with fresh solution (not water), and let the case air dry.

3 Ways to Know Contact Lenses Aren’t for You

Some people should not use contact lenses for vision correction. They include:

  • Anyone who is too busy to be compliant with contact lens safety measures and thorough hygiene habits
  • People who work where there is a lot of debris in the air, such as sawdust
  • People who have dry eye problems. “When you put a lens in the eye, it rests on tear film,” says Steinemann. “If you don’t make enough tears, you could be at increased risk for infection.”

Contact lenses are safe to use, but only if you follow your doctor’s advice and these simple rules of care.

How to Maintain Good Eye Health

Don’t take your eyes for granted. Protect your sight with these six tips:

1. Eat for Good Vision

Protecting your eyes starts with the food on your plate. Nutrients such as omega-3 fatty acids, lutein, zinc, and vitamins C and E might help ward off age-related vision problems such as macular degeneration and cataracts, studies show. Regularly eating these foods can help lead to good eye health:

  • Green, leafy vegetables such as spinach, kale, and collards
  • Salmon, tuna, and other oily fish
  • Eggs, nuts, beans, and other non-meat protein sources
  • Oranges and other citrus fruits or juices

Eating a well-balanced diet also helps you maintain a healthy weight, which makes you less likely to get obesity-related diseases such as type 2 diabetes. Diabetes is the leading cause of blindness in adults.

2. Quit Smoking

Smoking makes you more likely to get cataracts, optic nerve damage, andmacular degeneration. If you’ve tried to quit smoking before and started smoking again, keep trying. The more times you try to quit smoking, the more likely you are to succeed.

3. Wear Sunglasses

The right kind of sunglasses will help protect your eyes from the sun’s ultraviolet (UV) rays.

Too much UV exposure makes you more likely to get cataracts and macular degeneration.

Choose sunglasses that block 99% to 100% of both UVA and UVB rays. Wraparound lenses help protect your eyes from the side. Polarized lenses reduce glare when driving.

If you wear contact lenses, some offer UV protection. It’s still a good idea to wear sunglasses for more protection, though.

4. Use Safety Eyewear

If you work with hazardous or airborne materials on the job or at home, wear safety glasses or protective goggles every time.

Certain sports such as ice hockey, racquetball, and lacrosse can also lead to eye injury. Wear eye protection (such as helmets with protective face masks or sports goggles with polycarbonate lenses) to shield your eyes.

5. Look Away From the Computer Screen

Staring at a computer screen for too long can cause:

  • Eyestrain
  • Blurry vision
  • Trouble focusing at a distance
  • Dry eyes
  • Headaches
  • Neck, back, and shoulder pain

Taking the following steps to protect your eyes:

  • Make sure your glasses or contact lens prescription is up-to-date and adequate for computer use.
  • Some people may need glasses to help with contrast, glare, and eye strain when using a computer.
  • Position your computer so that your eyes are level with the top of the monitor. This allows you to look slightly down at the screen.
  • Try to avoid glare on your computer from windows and lights. Use an anti-glare screen if needed.
  • Choose a comfortable, supportive chair. Position it so that your feet are flat on the floor.
  • If your eyes are dry, blink more.
  • Every 20 minutes, rest your eyes by looking 20 feet away for 20 seconds. At least every 2 hours, get up and take a 15-minute break.

6. Visit Your Eye Doctor Regularly

Everyone, even young children, should get their eyes examined regularly. It helps you protect your sight and see your best.

Eye exams can also find some eye diseases, such as glaucoma, that have no symptoms. It’s important to find these diseases early on, when they’re easier to treat.

Depending on your eye health needs, you can see either an optometrist or an ophthalmologist for an eye exam. Ophthalmologists are medical doctors who specialize in eye care. They can provide general eye care, treat eye diseases, and perform eye surgery. Optometrists have had 4 years of specialized training after college. They provide general eye care and treat the most common eye diseases. They don’t do eye surgery.

A comprehensive eye exam might include:

  • Talking about your personal and family medical history
  • Taking vision tests to see if you have nearsightedness, farsightedness,astigmatism (a curved cornea that blurs vision), or presbyopia (age-related vision changes)
  • Tests to see how well your eyes work together
  • Eye pressure and optic nerve tests to check if you have glaucoma
  • External and microscopic examination of your eyes before and after dilation

You might also need other tests.

Varieties of spectacle lenses

Like many primary school students in India, your child wears spectacles. In fact, around the world, specs are the most widely-used aid to correct vision problems like myopia. To meet the different needs of wearers, there is a wide variety of specially designed lenses. Here, we explain some of them.

Lenses with different coating or tinting

1

a. UV Coating

This provides ultraviolet (UV) protection for your eyes by blocking damage to your eyes by the sun’s harmful rays. Overexposure to UV rays is believed to cause cataracts, retinal damage and other eye problems. Sunglasses should have at least 95% UV coating to prevent damage to your eyes.

1

b. Hard Coating

A clear, hard coating makes these lenses more scratch-resistant.

1

c. Multi-Coating

Lenses with an anti-reflective coating or multi-coating helps to minimise the glare, reflections, and halos around lights. This is useful for safety purposes when you are driving at night.

1

d. Photochromic

Photochromic lenses change from a light colour to a dark colour depending on the amount of UV light that they are exposed to.

1

e. Tinting

Tints are available on plastic as well as glass lenses

Caring for your spectacles

Proper care can help your pair last longer.

  1. Wash your spectacles in warm water daily. Wash or blow off dust or grit. Always dry them with a soft cotton or cleaning cloth. Never wipe them with paper products as these may scratch the lenses.
  2. To keep lenses scratch-free, do not place spectacles face down on any surface.
  3. When not in use, store your spectacles in their protective case. Do not put them into your pocket as they could fall out or get bent out of shape.
  4. Always put on or take off your spectacles with both hands, to keep them well-fitted and also preserve their life span.

The History of Wayfarer Sunglasses

Originally created by Ray-Ban, a high end manufacturer of sunglasses, Wayfarer sunglasses were extremely popular in the ’50s and ’60s. They were popularized once again in the ’80s, and have made yet another comeback in modern day fashion.

Wayfarers have been cited as the most popular selling sunglasses in history, although some believe this honor is held by the classic aviator style.  Either way, wayfarer sunglasses are incredibly popular.

Wayfarers were created by optical designer Raymond Stegeman in 1952 when he procured dozens of patents for Baush and Lomb, Ray-Ban’s parent company at the time.  At the time of their inception, the wayfarer was seen as a radical design that rivaled the Cadillac’s tail fin and design critic Stephen Bayley, the “distinctive trapezoidal frame spoke a non-verbal language that hinted at unstable dangerousness, but one nicely tempered by the sturdy arms which, according to the advertising, gave the frames a ‘masculine look.”  They wayfarer also ushered in the trend of glasses made of plastic and not wire or metal.

After the 60’s the sales of wayfarers declined and by 1980, with only 18,000 pairs sold, these classic shades were on the brink of extinction through discontinuation.  Yet in 1982, Ray-Ban signed a $50,000 – a-year deal with a company called Unique Product Placement to place the sunglasses in television and movies and between 1982 and 1987, Ray-Ban sunglasses appeared in over 60 movies and television shows per year.  You might remember some of these movies, like Tom Cruise in Risky Business,Madonna in Desperately Seeking Susan, and television shows like Miami Vice.  By 1983, sales of wayfarers skyrocketed to 360,000 pairs sold.   If you remember the 80’s then you remember these sunglasses and probably owned a pair.

Yet, again, but the 1990’s, wayfarers fell out of favor for styles like wraparound sunglasses and other styles.  In 2001, the style underwent a redesign with frames that were less angular and smaller and were also made of lighter injected plastic.  By the late 2000’s the sunglasses made a full recovery and are now very popular again.

To make the style trendy again using smart PR, edgy advertising and grass roots marketing efforts.  Every year since the wayfarer has shown signs of steady growth with no signs of stopping.

How to Pick Good Sunglasses

Sunglasses can give you instant James Dean cool, Audrey Hepburn glamour, or the rock star hipness of Bono. But they are much more than a fashion accessory.

Sunglasses are an essential tool in safeguarding the health of your eyes and the surrounding tissue.

Here’s what you need to know about what sunglasses can do for you (apart from style) and how to choose them.

Eye on UV Risks

Just as the sun’s ultraviolet (UV) rays can damage skin, they can also harm the lens and cornea of the eyes.

UV radiation increases your odds of getting cataracts, which cloud theeye’s lens and lead to diminished eyesight. It has also been linked tomacular degeneration, a treatable, but incurable disease of the macula, a part of the retina that is essential for sharp vision.

Other UV-related eye problems are pterygium and pingueculum. A pterygium occurs when the conjunctiva, the tissue that lays over the white of the eye, grows into the cornea. A pingueculum is a yellowish bump of tissue on the white of the eye.

Sunlight that bounces off highly reflective surfaces such as snow, water, sand, or pavement can be especially dangerous.

Photokeratitis is a corneal sunburn that’s also known as snow blindness. As the name suggests, skiers and snowboarders are particularly vulnerable to this temporary but acutely painful condition. “In photokeratitis, tiny blisters form on the surface of the cornea,” says Gail Royal, MD, an ophthalmologist in Myrtle Beach, S.C. “It’s a condition that will generally resolve on its own with proper medical treatment, but it’s uncomfortable enough to spoil your vacation.”

Sunglasses play a vital role in shielding the fragile tissue around the eye, says W. Lee Ball Jr., OD, an optometrist at Harvard Medical School’s Beth Israel Deaconess Medical Center. “This skin, including the eyelid itself, is very thin and vulnerable to skin cancer, and that’s especially troubling since dermatologists are reporting an epidemic in all types of skin cancer,” Ball says.

Royal, who includes a review of proper sunglass use during patient visits, admits she sometimes appeals to her patients’ vanity.

“I’ll point out that sunglasses will protect not just against basal cell and squamous cell carcinomas and melanoma,” she says, “but also against the formation of wrinkles like crow’s feet and the unsightly thickening of the skin that can sometimes be caused by UV exposure.”

Make Sunglasses a Daily Habit

Like sunscreen, sunglasses should be worn whenever you’re outdoors, year round.

“Just as we’ve learned that you can get a really nasty sunburn on an overcast, hazy day, you’re exposing your eyes to damaging UV rays on these days, too,” Royal says.

Sunglasses are especially important for children, says Peter Kehoe, OD, an Illinois optometrist who specializes in children’ vision.

“UV eye damage is cumulative over a lifetime,” Kehoe says, “so it’s important to make wearing sunglasses a habit early in life. What’s more, children’s eyes are especially vulnerable because they’re still developing.”

Protecting your eyes from the sun begins with picking the right pair of sunglasses. Here’s advice from eye care experts.

Look for Complete UVA/UVB Protection

Choose sunglasses that provide full protection against ultraviolet light. Look for a label or a sticker that says one or more of the following:

  • Lenses block 99% or 100% of UVB and UVA rays
  • Lenses meet ANSI Z80.3 blocking requirements. (This refers to standards set by the American National Standards Institute.)
  • UV 400 protection. (These block light rays with wavelengths up to 400 nanometers, which means that your eyes are shielded from even the tiniest UV rays.)

Choose the Right Hue

The coating that blocks UV radiation is clear, so a darker lens isn’t necessarily more effective than a lighter one. But hue does play an important role in color perception.

Yellow or rose tinted lenses can make it difficult to distinguish changes in traffic lights. Gray, green, and brown lenses minimize color distortion, and are a better choice when you’ll be behind the wheel.

Opt for Polarized Lenses If You Spend a Lot of Time on Water

Polarized lenses reduce glare by filtering out the reflected sunlight that bounces off surfaces like water or pavement. They’re a good option for boaters or water skiers, and they can cut down on glare from flat, smooth surfaces like road pavement or the hoods of cars.

The downside: It can be difficult to read your cell phone, GPS device, or a liquid-crystal display on a dashboard or ATM machine with polarized lenses.

Be aware that polarization has nothing to do with UV protection. So check the label to make sure the sunglasses provide full UV filtering.

Consider the Quality of the Lenses

Eye care experts agree that price isn’t a gauge of UV protection. But very inexpensive sunglasses are likely to contain lenses that are stamped out of a mold rather than ground and polished, and that can affect optical quality.

“Consistency is a concern with lower-priced glasses,” says Kehoe, a past president of the American Optometric Association. “You might find one pair that offers great clarity and another that’s the very same brand and model and highly distorted.”

To test optical quality, the FDA suggests focusing on a vertical edge or line. Move your head back and forth, allowing your eyes to sweep across the lens. “If there is any wiggle in the line,” the FDA guidelines say, “then the lenses may have an optical defect and you should choose another pair.”

Bigger is Better

Wraparound sunglasses offer the broadest protection against UV damage because they block more of the light that hits your eyes from the sides.

Sunglasses with large lenses and wide temples provide the next-best protection.

“Large lenses cover a wider area of skin so there’s a decreased window for UV penetration,” says Royal. “Sunglasses that come down to your cheekbones are a good choice.”

Think Jackie O’s iconic oversized glasses rather than John Lennon’s small, round shades.

Fit Matters

Sunglass frames should fit snugly on your nose and ears without pinching or rubbing. To prevent light from hitting your eyes from overhead, choose a pair that fits close to your face around the brow area, but not so close that your eyelashes are hitting the lenses, Royal says.

Whether you opt for high-priced designer sunglasses or a more affordable pair you find at your drugstore, you can easily find sunglasses that are flattering and functional. And protecting your eye health is one sunglass trend that will never go out of style.
