- I wonder if anyone has had any luck with those 'lazer' glasses
- with all the little pinholes cut in blackout lenses? From the
- little I know about optics it would seem to make sense. Basically
- I think what happens is the pinholes make any image focus regardless
- of what your lenses are doing so it allows the muscles to find
- thier 'home' (i.e. relaxed) position. What happens after a while is
- your brain 'remembers' which way to go to correct the image by
- reinforcing a correctly focused image at the 'home' position instead
- of glasses which reinforce a correctly focused image at in incorrect
- position.

- Not exactly. Pinhole glasses work on the same principles as the
- pinhole camera. Most people don't use pinhole glasses for the same
- reason most people don't use pinhole cameras: They don't work as well,
- tending to restrict contrast, brightness and field of view.
-
- The principle is exactly the same as with lenses, however. Pinhole
- glasses reduce the effort to read just as glass lenses do, so they are
- no better for your eyes than conventional glasses, just less effective.
