So I constantly lose my glasses but thankfully not my keys because they stay in my wallet which always stay right beside me but I'm one of those people that don't like to keep my glasses on my face all the time only when I need it so I need a GPS locator or just sound alarm device that can nicely attach to my glasses and can be used to make a loud sound or be located via Bluetooth or GPS when I essentially lose it or misplace it as I do fairly frequently.
It's one of those things that slightly annoy me as you can imagine I put it anywhere whereas my wallet is either beside me usually or on me.
TL;DR GPS Bluetooth locator with sound alarm to find my glasses when I eventually lose then through out the week / day
Hmm… irradiate them with plutonium. Then you can use a geiger counter to find them
*warning, may cause eye cancer, but seeing how your eyes are shit you'll have to weigh that risk up haha
