Photochromic lenses are very convenient, but they do have a drawback: Ultraviolet (UV) rays are required to activate the tint. Because most car windshields block a significant amount of UV, photochromic lenses usually don’t darken very well inside a car.

For the ultimate prescription eyewear suitable for all lighting conditions, some opticians recommend eyeglasses with photochromic lenses and a frame with integrated magnetic clip-on sunglasses.

The photochromic lenses provide automatic sun-sensitive light adjustments for greater comfort outdoors. And the clip-on sunglasses can be conveniently stored in your vehicle for those bright, sunny days when you need darker lenses.

UV and glare protection

As with non-prescription sunglasses, your primary concern when buying prescription sunglasses is that the lenses block 100 percent of the sun’s harmful UV rays. UV protection is unrelated to the color and density of the tint in sunglass lenses, so you can choose any lens color and darkness you like, as long as your optician verifies that the lenses provide 100 percent UV protection.

For added glare protection from light bouncing back from reflective surfaces (like water, snow, sand and concrete pavement), prescription polarized sunglasses are also available.

Cost of prescription sunglasses: Maybe less than you think!

Very important: Always make sure you discuss and make decisions about your eye care based upon a formal appointment with your optician.
