- Hi guys, I'm Doctor Mei Fleming
and welcome to an episode of ask an Eye Doc
where I answer your questions on social media.
Rosaline asks, "Do high end sunglasses protect your eyes
"any better than gas station sunglasses."
You buy glasses at a gas station?
These were really cheap,
are they really protecting my eyes?
A lot of high end glasses have polarization
which is a filter that filters out reflective light.
Also another feature is anti-reflective coating.
Have you ever noticed your wearing glasses
and you just feel like all this glare is coming
into your eyes.
That's what anti-reflective coating decreases.
Another feature of high end glasses
are mirror coatings which actually decrease
the amount of light that enters your eye.
When shopping for sunglasses
look for full UV coverage.
You're looking for a sticker that says UV 400
which covers both UVA and UVB lights which are
harmful for the eyes.
Be careful,
some glasses have stickers on them but don't actually
cover the full range.
That was a great question.
If you have nay more keep them coming at #AskAnEyeDoc.
