Emitted by the light from our screens, blue light has the highest energy wavelengths on the visible light spectrum. Similar to how UV-light overexposure harms our skin, blue-light overexposure can lead to eye discomfort and irritation (think: eye strain, dry eyes, eye fatigue, blurred vision, headaches). Blue light also suppresses melatonin secretion - the neurotransmitter that tells our minds and bodies to power off at night - which is why it is harder to fall asleep after spending hours in front of our screens every day.
That’s where we come in! Felix Gray’s clear lenses are intentionally designed to filter blue light - specifically, the highest energy wavelengths in the 400-440 nm range. Still interested in learning more? Head here to read on!
