National Sunglasses Day – 3 Tips for choosing the right sunglasses

UV radiation from both natural sunlight & artificial UV rays, like tanning beds, can damage the eye, affecting the cornea and lens.
Long-term exposure to UV radiation can lead to cataracts & skin cancer around the eyelids.
Always avoid looking directly at the sun as it can permanently scar the retina, the area at the back of the eye responsible for vision.
  • A wide-brimmed hat can block about half of the UV rays as it can limit rays that hit the eyes from above and also around sunglasses. What to look for in sunglasses

1. Choose quality sunglasses

Check for labels, hang tag or sticker which should state the amount of protection. Sunglasses should block out 99 to 100 percent of both UVA and UVB radiation and screen out 75 to 90 percent of visible light. Some of the higher-priced options with polycarbonate lenses claim to block 100 percent of the UV rays.

2. Inspect your sunglasses

Check to make sure your sunglass lenses are perfectly matched in color and free of scratches and distortion. Price does not necessarily correspond to protection. Just take the time to carefully inspect the lenses before you buy.

3. Wear gray-colored lenses

Gray-colored lenses reduce light intensity without altering the color of objects, providing the most natural color vision.
  • As to style think about the sides of your eyes, and consider sunglasses with wide or wraparound arms.
  • Children are at higher risk from harmful effects of UV rays because their eyes do not have the same ability as adults to protect from UV radiation. Kids also aspend more time playing outdoors.
  • UV radiation damage is cumulative over a lifetime, so you should begin protecting your child’s eyes now.
