Here's what the science says about blue light and how Felix Gray helps protect you.
How blue light disrupts your sleep
Research from Harvard Medical School shows that blue light exposure in the evening suppresses melatonin, the hormone responsible for regulating sleep. This disruption can delay sleep onset, reduce sleep quality, and make it harder to feel rested the next day.
Felix Gray lenses are designed to filter up to 15x more of the most impactful blue light than other clear lenses, while our amber lenses filter 23x the blue light, helping support natural melatonin production and better sleep patterns.
How blue light contributes to headaches
Studies show that prolonged blue light exposure increases digital eye strain, which can lead to tension headaches and trigger migraines. Overworked eye muscles and increased visual stress are common causes of screen-related pain.
In a study of 2000 customers, 65% of wearers reported a significant reduction in headache or migraine symptoms when wearing Felix Gray lenses during daily screen use.
How Blue Light From Digital Device Can Impact Your Focus
At Felix Gray, we design our blue light glasses for the way you actually live and work — in front of screens. Our lenses filter blue light and reduce digital eye strain, helping to minimise the visual fatigue, headaches, and blurry vision that can pull your attention away from what matters.
By easing the stress on your eyes during long screen sessions, we help make it easier to stay comfortable, clear-headed, and focused throughout the day.
Our lenses help make everyday screen time easier on your body.
