I think glasses should be detectible by sound. If you have very poor vision, then you can't
find your glasses when they fall off... If they were to emit a noise if one presses a button on
their keychain, then that would help out much. This wouldn't be neccesary for most
people.. but you can see
a hearing aid, why can't you hear glass
glow in the dark sunglasses
A different approach to finding lost spectacles. [egnor, Aug 03 2000, last modified Oct 05 2004]
||if i can't find my glasses you can forget about finding my keys.
||I want an arm-mounted thing like the Predator had in the first movie. THAT I'd buy.
||I wear contacts. Try finding a dropped contact without your contact in....And, it's true, finding key chains without the contacts is pretty difficult. If I have them in my pocket at the time I drop my contact that's great. (I only have one good eye) Now, if we can just miniturize the beeping circuit to fit invisibly in a contact lense. ;=)
