Photokeratitis is a type of “corneal sunburn” that results from exposure to extremely bright sunlight reflected off water, sand or snow. For example, “Snow blindness” is a form of photokeratitis caused by UV rays reflecting off ice and snow. Like a sunburn, photokeratitis is often not noticed until the damage is already done so precaution is your best cure.
 

You can protect your child’s eyes by ensuring they wear sunglasses when outdoors — even in cloudy weather (UV rays pass through clouds).
 

Intensity of UV Light Depends on Latitude & Altitude

The amount of UV light that reaches earth depends on the latitude and elevation. More UV rays reach the earth near the equator and at higher altitudes. When the sun is directly overhead in the middle of the day, you are being bombarded with the maximum UV radiation. Of course, this doesn’t mean your child can’t be outdoors in the middle of the day but make sure they are wearing sunglasses and sunscreen.

Pingueculas

A Pinguecula (pronounced pin- GWEK-yoo-la) is a small, yellowish bump or patch in the conjuctiva, near the cornea. Think of it like a callus on your skin but on your eye. It’s not yet entirely known what causes a pinguecula, but many think the cause may be frequent exposure to sunlight, dust or wind. These abnormal growths are usually non-cancerous and can often be treated with eye drops.
 

Guidelines for Buying Sunglasses

So hopefully you have a better appreciation for why your children need quality, comfortably fitting sunglasses. Here are a few tips on what to look for when purchasing sunglasses.
 

• UV rays – Sunglasses should block 99% to 100% of both types of ultraviolet rays: UV-A and UV-B.
• Fashion matters – Kids love to tease each other and sunglasses will be an easy target. Make sure you pick up something “cool”.
• Lens material – Lenses should be impact resistant and the frames should be bendable, unbreakable and/or have snap-on temples. Trivex is an impact resistant material and the best choice for active children.
• Have your child try on the sunglasses before purchasing. Make sure the lenses shield the eyes from most angles (above, below and either side) and block the light entering around the frame.
• Proper fit around the nose –  Young children’s noses are not fully developed which makes a comfortable fit on the nose tough. Many manufacturers are aware of this issue and make their bridges to fit small noses but be sure to check, otherwise your child will be looking over the top of their lenses all day long!
• Warranty – Non-prescription sunglasses will have a two year manufacturer defect warranty. If you are purchasing prescription sunglasses, please check out our “Kid’s Promise Warranty” now.
