It happens to everyone: you’re driving on a sunny day, and as you turn at just the right angle, the sun’s glare suddenly blinds you. Glare can be a mere nuisance—or, worse, a cause of accidents. Fortunately, there are effective ways to reduce it.
"The most effective way to reduce sun glare is to wear glasses with polarized lenses," says CEENTA optometrist Michael Spicola, OD. Glare is typically horizontally polarized, meaning that light travels in horizontal waves rather than scattering in every direction. When polarized film is applied to lenses, it absorbs horizontal light waves and allows other waves to pass through—significantly reducing glare.
Antireflective coatings are also good for reducing reflected light and thus cutting down on glare. They are predominantly used on clear lenses, but are often incorporated into high-quality sunglass lenses as well.
"Simply putting down the visor in your car can help reduce glare," Dr. Spicola said.
The sun’s rays are also a factor in cataract development, since cataracts grow in part from exposure to ultraviolet radiation. "Not only does wearing sunglasses while you drive cut down on glare, but they can also delay cataracts. Most lenses – both sunglass and regular – and some contact lenses are UV-protected. Even some windshields have UV protection," Dr. Spicola said. However, they won’t protect your eyes from glare.

CEENTA cataract surgeon Vipul Shah, MD, appeared on WSOC's The Daily Two to discuss cataract development and sun protection.
Many people think the most important time to wear sunglasses is the middle of the day, when the sun is at its highest. But just as important is early morning and late afternoon, when the sun is potentially most damaging to your eyes.
Keep your eyes clear.
