Decent glasses is designed for shortsighted groups.At nights,it is a waste of time and also inconvenient for people to grope for the glasses.This design attaches the illuminant to the frame of the glasses and hence people can
find it when they take it off.The material of glasses frame is temperature sensing so that when people put in on at night,
the chip inside the frame will cut off the light and turn the glasses into the normal one to wear.
