The beach, the backyard pool and even the ski slopes are very inviting but eye damage can be just around the corner. The most immediate danger is photokeratitis, a painful type of corneal sunburn linked to the bright sunlight reflected off water, sand and snow. Reflected sunlight can double the exposure of harmful UV rays. Long-term exposure to UV light can lead to cataracts, skin cancer around the eyelids and even damage to the retina.
Ultraviolet damage is cumulative. Exposure to UV light, wind, and dryness can cause pingueculas. These are abnormal, but usually non-cancerous, growths on the white part of the eye near the nose. They can start in the teen years or early adulthood and can grow onto the front part of the cornea, possibly requiring surgical removal. Protection from UV exposure and wind starting early in life can help reduce the incidence of these growths. It is estimated that 80% of lifetime absorption to UV light occurs before the age of 18. Unfortunately, a recent survey found that a high percentage of parents are unaware of the potential for damage and rarely protect their children’s eyes.
Sunglasses with UV protection can help boost the eyes’ ability to filter out the damaging rays. However, sunglasses that do not block UV rays should be avoided. Sunglasses shade the eyes from the bright sun and cause the pupils to dilate somewhat. If the UV rays are not blocked by the lenses, more UV enters the eyes that if no lenses are worn.
Guidelines for selecting sunglasses for your child:
- Sunglasses should block 99% to 100% of both types of ultraviolet rays: UV-A and UV-B. Be wary of labels that claim a product blocks harmful UV without specifying exactly what amount of UV rays they block.
- Select sunglasses that suit children’s active lifestyles. Lenses should be impact resistant and the frames should be bendable, unbreakable and/or have snap-on temples. Polycarbonate is the most impact resistant material available and the best choice for active children. Children’s sunglasses should never be made of glass.
- Check the lenses carefully for scratches, bubbles and distortions. Here’s an easy test for non-prescription lenses: hold the glasses away from your eyes and look through the lenses at a good horizontal or vertical line, such as a window frame. If the line appears wavy instead of straight, the glasses may actually make it more difficult to see (although some distortion may be seen with prescription lenses for corrective purposes).
- Have your child try on the sunglasses before making a purchase. The lenses should be large enough to shield the eyes from most angles (above, below and either side) and to block light that enters in around the frames. The sunglasses should also fit snugly against the bridge of the child’s nose in order to reduce the amount of sunlight that enters the eyes.
- Check the sunglasses periodically to make sure they fit well and are not damaged. Children often don’t complain about their vision even when there is a problem. A regular check of their glasses is a good idea.
- Fashion should be the last thing you think about when buying sunglasses. Look at the amount of UV protection, lens quality, and durability to assure that you buy
the right sunglasses for your child.
If you have questions or concerns, always consult your eye doctor.
