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). Exclusive to Tiger Specs, these Jelli screen glasses are made entirely from polycarbonate plastic providing extra strength while also being incredibly lightweight and durable. They feature a smart grey tortoiseshell patterned frame with a soft touch finish and extra thin large square shaped lenses. These glasses also come supplied with a matching soft pouch.
