Will these fit over my prescription glasses?

They are a mid-sized Slim Line fitover, so they suit average-width frames. Very large or thick frames may not fit under the shell.

Are they good for driving?

Yes. The polarized gray lenses cut road and dashboard glare, and the 13% tint handles bright daylight. They are too dark for night driving.

How dark are the lenses?

Visible light transmission is 13%, so they are fairly dark. That suits sun and water glare but not dim or overcast conditions.

Do they block blue light?

Yes. Cocoons rates the lenses to filter 80% of blue light (HEV) in addition to UV400 protection.

What is the warranty?

Cocoons backs the frame with a manufacturer's limited lifetime warranty. Keep your proof of purchase for a claim.

When is the price lowest?

The best new price is $59.99 at eBay as of November 5, 2026, with 3 stores listing it new. Check the price history before buying to see whether that is below the usual range.
