Reminds me of a friend I had in HS who got an ad for "X-ray glasses" out of the back of one of those cheapie Marvel or Dell comic books. I think they cost $5-6 !! .... and the ad had a drawing of a guy looking through girl's dresses etc. So he orders them ! We told him it was a scam (rip off then); there's NO way they could sell x-ray glasses (safety problem) and esp for $5 !! But he wouldn't listen !
So about a week later they come in the mail (no UPS or Fed Ex then). They are a set of frames with cardboard in place of the glass. The middle of the cardboard "lenses" has a small hole in each and wedged between the layers of cardboard are some fine feathers! YES feathers ! So when you look through them the feathers kind of give you double vision ! So you look at your arm and you see your arm and a slightly smaller arm inside that one (X-ray !) We razzed him for months over those !! What a maroon !!!
Glasses and lenses are the biggest rip off !! My wife worked for an optometrist in CA and they'd buy frames for <$5 a pair and sell for $100-200 !! Even the high $300+ frames cost them < $20 !! WHat a SCAM ! Buy a set on line for $15-20 !! And all that BS with coatings and crap... it's like running Rain-X over your car windshield. Takes <1 minute, 2-3¢ in cost, and they charge you an extra $20-25 !! What a load of sh ... caca!!
Get your Rx and buy on line. My son did and he got 2 pair for about $20 each. Works fine for him ! A regular eye service would have cost him 5-6 X that ! . . (and he got coatings etc too, but they charge an extra $1 for them, not $20 !)
