Answer 1

Last paragraph of the wiki entry "These claims have been analyzed, but no scientific evidence has been found to support them, and they are no longer allowed to be made in the United States under the terms of a legal settlement with the Federal Trade Commission". Says it all really!

Answer 2

These have been sold, on and off, for years. If they really worked, mainstream opticians would be selling them.

Answer 3

Pinholing just cuts out deviant light. You can see better with them on, but they look hideous and Rx glasses work so much better. They do not provide any sort of therapy whatsoever.

Answer 4

Yes, he said, wearily...

"Pinhole glasses can help a wide range of eye problems:

Myopia (short sightedness)

Hyperopia (long sightedness)

Presbyopia (age-related reduced range of focus)

Astigmatism

Cataracts

Eye strain (from computer screens) "

(from your eBay site)

With cataracts!?

You don't need to look any further...

If anyone can say that, they are utterly ignorant or fraudulent.
