FRETREE Bluelight Blocker Glasses How Does Blue Light Affect Sleep? After sundown, the lack of light signals our bodies to start producing melatonin, the hormone responsible for making us fall asleep. But today, we're exposed to light all day and into the night. Blue light waves can be especially problematic because they keep us alert. What Are Blue Light Blocking Glasses? Blue light blocking glasses have filters in lenses that block or absorb blue light, and in some cases UV light, from getting through. If you use them while looking at a screen, especially after dark, they can help reduce exposure to blue light waves. Should I Get Blue Light Blocking Glasses? The idea is that this helps break your focus from your screen, allowing your eye muscles to relax and stave off eye strain.
