Blue-Light Blocking Glasses for Sleep
Protect your circadian rhythm from screen exposure with the right eyewear.
Blue light from screens suppresses melatonin production by up to 50%. Wearing blue-light blocking glasses 2-3 hours before bed can restore natural sleep onset and improve sleep quality.
How Blue Light Affects Sleep
Blue light (450-495nm wavelength) signals your brain that it's daytime, suppressing melatonin and delaying your circadian rhythm. This makes falling asleep harder and reduces sleep quality.
What the Research Says
Studies show wearing amber-tinted blue-light blocking glasses for 2 hours before bed increased melatonin by 58% and improved sleep quality ratings significantly.
Choosing the Right Glasses
Look for amber or orange-tinted lenses that block 90%+ of blue light. Clear 'blue-light' lenses block minimal blue light and are mostly marketing. Comfort and fit matter for nightly use.
