There is an instant & constant need to locate one's reading glasses [spectacles], especially for the elders. I used to have those cheap plastic ones kept at vantage points like the bedside table, Laptop Bag,Car, Bathroom etc. Now when the power of both eyes are different it has become difficult to make so many. There is need to have some sort of BOS [beeper-on-spectacles] which can be activated thru ~ Ring-on-Finger[ROF] or Pendant or anything that can be kept on the body permanently. In fact the keychain may also require one of these beepers. With RF technology becoming cheaper by the day it should be possible....
