Sonar (Black)

These specialist blue light glasses have blue filter lenses which reduce, by 40%, the amount of blue light reaching the eyes from all types of digital 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. These screen glasses feature a lightweight matt black semi-rimless frame so are super comfortable and come supplied with a matching soft pouch. Available in a range of reading strengths as well as with clear lenses/without correction (+0.00).
