Review on 👓 CHEERS DEVICES 5 Pack Reading Glasses: Blue Light Blocking Eyeglasses for Men & Women, Effective Computer Readers with Anti Glare Technology by Aaron Martz

The glasses themselves were fine but be aware the box has 'blue light' and a special card - NO instructions and NO warnings. We thought we should use blue light and shine it through the glasses to demonstrate that they block blue light, so we put them on the table and shined the light through the lenses onto a piece of paper for a few seconds. It definitely blocked most of the light. Then we tried the same thing with the current glasses to see if there was a difference - there was a difference - but it also created a dark spot on the prescription glasses the size of an eraser. It's like he burned the lenses and turned the paper dark brown - again in just a few seconds. By letting the glasses cool down and running the lenses under cold water for a few minutes I was able to make the stain go away, but imagine what would happen if someone did this experiment with glasses! I'm pretty sure it would be very harmful to your eyes. The aim of showing that they work was good, but instructions and warnings must be included!
