A round frame softens an angular face and adds a little academic charm to a video call. Our round blue light glasses pair that shape with lenses that filter some of the blue light from phones, tablets and computers. Choose clear, non-prescription lenses if you just want the filter, or a reading strength from +1.0 to +3.5 if small text is also a struggle. Frames come in tortoiseshell, black, blue, grey, pink and multi-colour, in glossy plastic or matt, soft matte and rubber-textured finishes, and in narrow, average and full widths. They make a smart second pair for the office or the sofa. Each one is designed in the UK, with a one-year warranty and 60-day returns on every order. read less
