Question: Whats that box of sand that my optometrist uses to work with my eyeglasses!?
Answers:
It is heated sand, just like you said!. It gets the frame warm so the optician can adjust it without it breaking!.Www@Answer-Health@Com
It isn't sand actually, it is very small glass beads!.
It just warms up the plastic parts of a frame to make them more pliable!.
Most places use a hot air blower instead of the beads now!.Www@Answer-Health@Com
