Felix Gray’s amber lenses filter up to 23 times more of the most impactful blue light emitted by screens, helping to reduce disruption to your body’s natural sleep signals. The advanced formulation supports melatonin production, with clinical evidence showing it can increase natural melatonin secretion by up to two times. By limiting exposure to stimulating light in the evening, these lenses help prepare the body for restful sleep.

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.

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.
