I usually buy glasses for less than $20 as long as they fit well, are
comfortable, and, looking through them, they seem to be not grossly
distorting or anything like that. I had a good pair of sunglasses
once and they didn't seem to function any better than the cheap ones,
and they succumbed to my abuse just as quickly - abuse in the form of
mistreatment and mis-placement, if you know what I mean.


I use the $20 jobs that fit over my prescription glasses. They do the job and I
don't have to pay $450 for a pair of prescription sunglasses.

Wearing a cap with a black underside to the bill helps tremendously.


When I buy new eyeglasses, I have the optical shop send the frames away
(titanium) and have a pair of sunglasses custom made for a perfect fit.
Costs me $90 - 100. each time.
