For years, we’ve referred to them casually as “shades.” For sure, that nickname reflects the laid-back, cool vibe that goes along with sunglasses. And for many, they mean fashion, not health.
Think again. We talked with Stephen Cohen, a VSP doctor from Scottsdale, Arizona, to find out the facts.
“Sunglasses used to be more about looking stylish than about taking care of your vision, but not anymore,” says Dr. Cohen. “Today, there’s increasing evidence that ultraviolet rays in sunlight can significantly increase your risk of developing cataracts and macular degeneration.” Both conditions usually affect older people, and it’s no wonder since years and years of sun exposure leave their mark over time.
The doctor adds, “Because both conditions can threaten healthy vision, I recommend wearing sunglasses on sunny days year-round. Plus, you’ll experience better night vision when you wear sunglasses on sunny days.”
There are a few key things to look for when picking the right pair of shades for you. Says Dr. Cohen: “When buying sunglasses, make sure they carry a consumer-protection label stating they’re 99-100% UV-absorbent, or provide UV absorption up to 400 nanometers (nm).
“Once you’ve eliminated the threat from UV light, you can focus on other issues, such as reducing glare and choosing a tint that will allow you to control the degree of brightness reaching your eyes.”
