Sunglasses are a major fashion accessory, and also a great way to protect your eyes.
Unfortunately, even expensive designer sunglasses don’t guarantee proper protection.
Whether you want new aviators or need prescription sunglasses, here are guidelines for sunglasses that are good for both your eyes and your look.
The sun: We assume that sunglasses protect our eyes from sun damage, but this isn’t always true. The darkness or color of a lens doesn’t indicate how well your shades block out UV and blue light: lenses have to be tested against UV protection standards. In the US, lenses should block out 99% of UV-B, and let in UV-A at 30% the rate of visual light.
Ourselves: Sunglasses block visual light, so they could critically impair our driving. Sunglasses should never be worn while driving at night, and should be approved for daytime driving.
Other risks: Neither standard nor prescription sunglasses are intended for protecting against artificial light sources (such as sun lamps) or for industrial safety.
Want to look good, but also see clearly? The wiggly line test helps check for lens issues.
The wiggly line test: Look at a vertical edge or line. Move your head back and forth, allowing your eye to sweep across the lens as you look at the line. If the line wiggles, the lens may have a defect and you should look for another pair.
When you wear glasses every day, you want them to suit your personal style. Fortunately, there are many designer frames for both men and women, in all sorts of modern and retro fashions. Before settling on one of the latest eyewear trends, check with your eye doctor to ensure that your prescription glasses are right for you.
