All About Sunglasses

Spring is in the air! That probably means you’re spending more time outdoors. And with luck, much of that time will be under sunny skies. Wearing sunglasses when you’re out on a bright day serves a couple of different purposes–they make you look cool while also protecting your eyes.

Why Should You Wear Sunglasses?

Protect your eyes against sunlight. Ultraviolet light, which is invisible, has many damaging effects. UV-A and UV-B light can hurt the corneas, lenses and retinas of your eyes. Blue visible light can also damage your retinas.

Travel more safely with the best contrast. Different colors of sunglasses can increase contrast. When sunglasses are too dark, contrast is reduced and you might not see a curb, step, or a crack in the sidewalk. This can lead to a fall. Choose a pair of sunglasses that best enhances contrast for you.

Make your eyes more comfortable. Do you squint when light is too bright? Your eyes might be sensitive to sunlight.

Tips for Making the Most Out of Your Sunglasses:

  • Wear sunglasses whenever you are outside, even on cloudy days.
  • You might need more than one pair of sunglasses depending on the time of day or activity.
  • Only buy sunglasses that provide 100% protection from UV rays. Lightly-tinted and even clear lenses can provide just as much UV protection as darker tinted lenses.
  • To guard against blue light, get sunglasses that have yellow in the tint, such as amber, orange, yellow and plum.
  • If you do activities where there is a lot of reflected light, such as boating or skiing, get sunglasses that are polarized.
  • For light-sensitive eyes, look for darker sunglasses, but be sure that they aren’t too dark and reduce contrast too much.
  • To find good contrast, try on many pairs of sunglasses and note the contrast when looking at an edge of a building and the background.
  • Before buying, go outside to natural light–colors are not the same when compared with fluorescent lights.

What Are Some Types of Sunglasses?

Non-fit-over frames are sunglasses that are worn alone. They are often made of plastic and come in many colors.

Fit-overs go over your regular eyeglasses and usually have side and top coverage. They come in lots of shades and in light, medium and dark tints.

Clip-on sunglasses are clipped to the top of existing eyeglasses and come down over the front. They don’t provide protection from light coming in from the sides or top and have more limited tints.

Slip-in sunglasses are slipped inside existing eyeglasses and hook to the top of the frame. They provide side and top protection but also don’t come in many color options.
