I agree. Not a bad idea at all. Where are all sceptics? I wonder.

The same idea can alsobe applied to key rings, electrical switches and so on.

Its a good commercial idea dude. Go ahead.

You want cheap and best frames from Asia?

Want me to get them developed for you?

Contact me.

Without doubt the frames need some energy to glow. There are two possible principles it could be based on.

1) phosphorescence

2) energy source (battery/accumulator)

In case 1) the glow would expire after some time (minutes) while in case 2) it would be cumbersome and need recharging or battery change.

It should be possible to utilize materials that fluoresce under ultra-violet light. A small ultra-violet flashlight shined in the dark would be able to reveal articles in a dark room.

There was another post earlier that referred to "beta lights". These use a radioactive isotope to flouresce another compound. The old radium dial watches used the same idea but was abandoned (or banned??? in 1968) due to workers deaths. Apparently if you breath a bunch of radioactive dust with a 1600 year half-life it isn't so good for you as it tends to accumulate in your bones

However, the amount of radiation emitted by the paint on the dials is considered small enough to be safe. So.... would this type of paint a solution to this problem? Obviously you wouldn't want to use radium but another isotope with a short half-life to minimize the risk, maybe promethium (half-life 2.6 years)???

Or maybe this would make the glasses to costly for the general user.

A shorter half-life does not make a radioactive material any less unhealthy. It would only make it become safer sooner.

Sand, the UV flashlight idea is no good. To find his glasses he would first have to find the flashlight!

I was aware of the problem, but the flashlight could be kept in a known and easily available place whereas the other objects might be less easily kept track of.

In the Czech Republic we have an idiom that could be translated as "to shoot a sparrow with a cannon" which means doing an easy thing by means of something very complex.

Why use "glowglasses" and UV flashlight when i can use ordinary glasses and ordinary flashlight?

Because an ordinary flashlight will illuminate an entire area filled with all sorts of objects while a UV flashlight in the dark will brilliantly pick out any objects that will only respond to UV light.
