These specialist blue light glasses have blue filter lenses which reduce the amount of blue light reaching the eyes from screens such as computers, smartphones, tablets and gaming devices. The blue filter lenses may reduce the problems of eye strain and headaches associated with working in front of screens for long periods as well as aid sleep, so are also ideal for screen reading in the evening. They are available in a range of reading strengths, as well as clear lens/without correction (+0.00). These screen glasses feature a classic frame shape in an attractive deep blue colour with a matt soft-touch finish and large lenses. These glasses feature dual rivet detailing at the frame edge and along the temples, have spring hinges for fit and comfort and come supplied with a matching drawstring pouch.
