Brand new in box! IZIPIZI Screen Glasses In Pantos/Round Shape MoMA All "LED screens" (smartphones, tablets, computer screens, television) emit "blue light", which is particularly harmful to the eyes.SCREEN glasses filter out 40% of the blue light emitted by screens, thus reducing eye fatigue, eye irritation and headaches. This feature is achieved by a treatment that makes the lenses slightly yellow whilst not agumenting the visability of true colours. Rubber touch, flex temples, designer frame: comfort and style guaranteed.Stay connected without any worry!
