Screen protection glasses - filters 40% of blue light - shape #D: round, timeless, bestseller - mixed and universal model - storage pouch included in the box. On average, we spend over 50 hours a week using smartphones, looking at our computer and television screens, or playing video games. However, all these screens from a modern generation with "LED backlighting" emit "blue" light also called HEV (High Visible Energy). All "LED screens" (smartphones, tablets, computer screens, television) emit "blue light", which is particularly harmful to the eyes. By filtering 40% of this blue light, our #Screen collection has lenses that will soften your daily life, protect your eyes, while guaranteeing you an ultra fashionable look. Rubber feel, flexible temples, designer frames: comfort and style guaranteed. Stay connected with peace of mind! This model meets European standards for pre-assembled glasses (NF EN 14139) and international standards for corrective spectacle frames (ISO 12870).
