Hi all,
I've recently annoyingly discovered that my glasses produce a slightly clearer image if I look through the very bottom of the lenses. To do this, however, I need to tilt my head back slightly and look downwards slightly - if I keep at this I'll either fall & have an accident or put my neck out!
With all the debate about lense quality in binoculars, has there ever been any investigation into the quality of lenses available for glasses and for that matter the coatings too.
Many glasses these days come with some form of anti-glare coating and I think you can get hold of "flattened" lenses, which might be the problem with my glasses.
Any thoughts on this subject - or can you point in the direction of an old thread if need be?
Hi Eric,
May we assume your glasses are not bi- or tri- focal? IMO the use of eyeglasses throws a random element into the mix. Not only are the factors you mentioned at work, but also magnification differences, off-axis effects, etc. In another thread I've asked why binoculars aren't made so that personal prescription lenses can be inserted at the ocular — but basically that's put off as whacko.

When I got my latest pair of spectacles I had the choice of basic lenses or upgrades from Nikon or Zeiss. Glass of the highes quality can be had in specs these days becuase the big names in optics are very strong in the medical imaging and lens fields.
