These stylish polycarbonate framed fitover glasses provide complete rejection of the light known to cause suppression of melatonin. They can be used just as well without wearing them over prescription glasses. They provide high contrast and intensify backgrounds allowing the wearer to see objects more clearly. They are suitable for use inside or outside including working at a computer, watching television and are also helpful for reading. They are sized to fit over the prescription glasses worn by most adults. These particular glasses are for adults with relatively smaller head sizes. The polycarbonate lenses are treated with a hard coat to help prevent scratching. The frames have a matte finish, with silvering on the front and side temples.

NOTE:Care should be taken after retiring at night not to expose your eyes to ordinary light which contains blue light. Because of this, if some light is needed, we highly recommend using LowBlueLights LED night lights.
