Felix Gray Blue Light blocking glasses are in a class all their own. Handcrafted Italian acetate frames with proprietary lenses provide the perfect balance between fashion and function making these a necessity within the computer screen, or gaming heavy lifestyle that a lot of us have. By filtering Blue Light and eliminating glare as much as possible, you are relieving an enormous amount of eye strain as you go about your day. Blue Light is emitted by all computer screens, and studies show it is linked to eye strain, sleep cycle disruption, and potentially macular degeneration. Glare creates unnecessary feedback that impacts vision and creates stress on your eyes. Felix Gray's filtering technology is embedded directly within the lenses, so 50% of all Blue Light and almost 90% of the highest range are filtered out. Premium anti-glare and UV protection are also applied, with no blue-reflective coating and an unnoticeable tint on the lenses themselves.
