Can one purchase a spray to apply to eyeglasses to provide anti reflection?
I have Rx inserts behing sunglasses and Im pretty sure there is an issue
with light bouncing around off the Rx lenses.  So I though I could spray
something on them to help the reflection issue.  (this was an option that I
did not get when I ordered the lenses).  It would be ok to have to reapply
and cleaning .

any thoughts?  thanks!
