With screen time at an all-time high, blue light-blocking glasses have become a popular accessory. But do they work? Not exactly in the way you might think. Blue light isn’t the main cause of digital eye strain—that’s more about prolonged focus and insufficient blinking. However, reducing blue light exposure in the evening may help regulate your sleep cycle by supporting melatonin production.
Instead of relying solely on glasses, follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. Combine this with screen breaks and good lighting to truly protect your eyes and improve comfort.
Blue light glasses can support better sleep by reducing evening exposure, but they’re not a cure-all for digital eye strain. The discomfort from screens is more about prolonged focus and inadequate blinking. Pair blue light glasses with the 20-20-20 rule and regular screen breaks for optimal eye comfort and overall well-being.
