ZZ Top knows what’s up. And thankfully, it is pretty easy to find a pair of sunglasses that looks good and protects your eyes — no matter what your budget is.

To help make the experience of buying a pair of sunglasses a little less confusing, here’s the truth about some of the most common myths about sunglasses:

3 Myths About Cheap Sunglasses 

Myth #1: Sunglasses with 100% UV protection are expensive

False: You do not have to pay a premium for proper UV protection. While more expensive sunglasses may offer more stylish frames, higher quality lenses, sharper images and less glare, it is very easy to find inexpensive glasses that offer 100% UV protection.

Myth #2: Lenses with darker tints are more protective than lenses with a lighter tint

False: The tint of the lens has nothing to do with the UV protection of the glasses. A clear lens with no tint and 100% UV protection is better for your eyes than dark, heavily tinted sunglasses without UV protection. In fact, dark lenses without adequate UV protection are actually worse for your eyes than not wearing glasses at all, because the dark tint causes your pupils to become dilated, thus exposing your eyes to more harmful UV light.

Myth #3: Photochromic lenses don’t block out UV rays as well as regular sunglasses

False: As long as they offer 100% UV protection, photochromic (such as Transitions-brand lenses) lenses provide the same level of UV protection as regular sunglasses.
