Pinhole glasses! MAY help some people with poor eyesight. What are they and do they work?

Описание: As a self-confessed gadget nut, I'm always looking for new (to me at least) gadgets especially items that may help with my poor eyesight and so, when I came across these 'pinhole' glasses recently that claimed to be able to help some people with sight issues and possibly even help improve their sight, I was intrigued and, when I discovered just how CHEAP they were, I got a few pairs (I would have been happy with just one pair but Amazon were selling multiple pairs so cheap that I thought I might as well get a few (if they worked - great! I could keep a pair at home, work, when travelling, etc., If they didn't work, they were so cheap I would just give them away!).

If I am honest, I was VERY sceptical that something so basic (a pair of plastic glasses with loads of small pin-holes instead of lenses) and cheap (I got four pairs for less than a tenner) would do ANYTHING at all (and I knew they wouldn't be able to help with my left eye as I've been pretty much blind in that one all my life) but, to my surprise, the improvement I noticed in my right eye when I put them on was actually very noticeable.

Granted, they are not as convenient as 'normal glasses', you look daft wearing them (and OBVIOUSLY you shouldn't wear them when driving or operating equipment, etc.,) and they only really work if you're focusing on specific text/images and I'm sure they won't work for everyone (my wife also has sight issues and wears bifocal glasses and they didn't work at all for her) but, for the price, I reckon it's worth a try!
