Question 1

Are cheap sunglasses okay for UV protection?

Accepted Answer

Yes — if they carry a UV400 or 100% UV protection label. UV protection is a coating applied to the lens, not a feature that depends on price. A $15 pair with UV400 rating protects your eyes as effectively as a $300 designer pair with the same rating. Where more expensive sunglasses differ is in optical clarity, polarization, durability, and frame quality — all of which matter for comfort and visual performance, but not for UV safety.

Question 2

Do my kids need sunglasses?

Accepted Answer

Yes — children's eyes are more vulnerable to UV damage than adults'. Their lenses are clearer and transmit more UV radiation to the retina. Since UV damage is cumulative over a lifetime, protecting children's eyes early reduces their long-term risk of cataracts and macular degeneration. Look for UV400-rated lenses in wrap or large-frame styles that stay on during active play.

Question 3

Do contact lenses protect against UV?

Accepted Answer

Most contact lenses do not provide meaningful UV protection. Even UV-blocking contact lenses don't cover the entire eye surface — the white of the eye remains exposed. Sunglasses are necessary regardless of contact lens type.

Question 4

Can I get UV damage on a cloudy day?

Accepted Answer

Yes. Up to 80% of UV rays penetrate cloud cover. UV index can also be surprisingly high in winter and at higher elevations. UV protection should be a year-round habit, not just a summer precaution.

Question 5

What's the difference between polarized and UV-protected lenses?

Accepted Answer

These are two separate features. UV protection blocks harmful ultraviolet radiation — this is the critical safety feature. Polarization reduces glare from reflected horizontal light, improving visual comfort. A lens can have both, one, or neither. Always confirm UV400 rating first; polarization is a comfort upgrade worth having if you spend time driving, near water, or in bright outdoor conditions.

Question 6

How often should I have my eyes examined for UV damage?

Accepted Answer

Adults should have a comprehensive dilated eye exam every one to two years, or more frequently with risk factors. UV-related conditions like early cataracts and macular degeneration can be detected long before you notice vision changes — early detection is the key to protecting your long-term vision.
