Blue light gets a bad reputation, but it isn’t the main cause of eye strain— our screen habits are. When we stare at our devices, we blink significantly less, leading to dryness and fatigue. And while blue light from screens won't cause permanent damage, it does disrupt your sleep by suppressing melatonin and interrupting your circadian rhythm.
Rather than relying on blue light glasses, we recommend implementing the 20-20-20 rule: every 20 minutes, look 20 feet away for 20 seconds to give your focusing muscles a break.
