Protecting Your Eyes Against Summer's Rays
summer upon us, people are taking out their sunscreen and shades to
help protect against the sun's harmful rays. But are your sunglasses
doing more harm than good?
sunglasses actually may cause more problems if they don't have adequate
ultraviolet (UV) protection. When you wear dark sunglasses, your pupils
enlarge to allow light in, but if your sunglasses don't have proper UVA
protection, you may be letting in the sun's harmful rays instead of
keeping them out, warns the American Academy of Opthalmology.
that exposure to bright sunlight can increase the risk of developing
cataracts and macular degeneration, both leading causes of vision loss
among older adults. The more exposure to bright light, the greater the
chance of developing these eye conditions, said Dr. Martin Mainster,
Here's how to ensure your eyes are protected, the Academy noted:
sunglasses that block ultraviolet rays. Don't be deceived by color or
cost. The ability to block UV light is not dependent on the darkness of
the light or the price tag.
- Ideally, your sunglasses should wrap all the way around to your temples, so the sun's rays can't enter from the side.
addition to your sunglasses, wear a broad-rimmed hat to protect your
eyes. Don't be fooled by a cloudy day. The sun's rays can pass through
the haze and thin clouds.
- Even if you wear contacts with UV protection, remember your sunglasses.
to the damage caused by a lifetime of exposure to bright sun, you need
to protect your eyes from acute damage caused by single outings on very
bright days. Excessive exposure to ultraviolet light reflected off
sand, snow or pavement can damage the cornea, the eye's surface.
Similar to a sunburn on your skin, corneal ultraviolet injuries are
painful, but usually heal quickly.
