Nash - Black

Felix Gray’s clear lenses use a proprietary formula that filters up to 15 times more of the most impactful blue light than standard clear lenses. This added level of filtration supports the eyes during extended exposure to screens and artificial light, helping to reduce potential visual discomfort. The virtually clear finish makes them suitable for everyday wear without affecting colour perception.

Founded in 2016 by David Roger with co-founder Chris Benedict, Felix Gray set out to pioneer the category of blue light eyewear, grounded in the mission to boost digital wellness, helping people live healthier, more productive lives amid heavy screen use. Roger teamed up with experts to create eyewear that blends function, science, and style. Felix Gray glasses filter blue light and reduce glare without distorting colour or adding a yellow tint. The brand’s lenses are backed by research and designed to support long hours in front of screens. With science-led design and premium materials, Felix Gray helps you protect your eyes, reduce discomfort, and focus better during screen time.

Wear daily during screen exposure or prolonged use of digital devices to help reduce visual discomfort. Clean lenses regularly using a microfibre cloth and lens-safe solution. Avoid abrasive cleaners and rough materials that may damage the coating. Store in a protective case when not in use to prevent scratches or warping. Keep away from direct heat or prolonged sunlight to maintain frame integrity.
