Hi all:

I'm not sure if this group is the right place to ask about it. If I'm
posting on the wrong group, please accept my apology and would
appreciate it if you can guide me to the right group for the question.

My question is: I have a pair of sun-glasses with high-index lenses.
Everything's fine except that when the sun is shining on my face at a
high angle from the front, I can see my the reflection of my eyes and
face on the lenses. I've heard that high-index lens can do well with AR
coating. I'm wondering if sunglasses with high-index lens need AR
coating (some say it doesn't). Since it's expensive to get the coating,
I'd like to know if I do go get the coating, will the
seeing-my-face-in-my-glasses problem go away?

If the lenses were polarized polycarbonate lenses, will that problem be
there?

Thanks in advance for your response.

Charles
