So here's a question for you—when was the last time you fell asleep without looking at your phone first? If you're like most people, you probably can't remember, and that little habit might be costing you more than you think. Let's talk about what's actually happening when you scroll through your phone at night. Your screen emits something called blue light, which sits in the 380 to 550 nanometer range of the visible spectrum. That's the same type of light that dominates natural daylight, and your brain can't really tell the difference between sunshine and your smartphone. When your eyes pick up this light, they send a signal to your brain that says "hey, it's daytime, stay alert." Your brain responds by suppressing melatonin, which is the hormone that makes you feel drowsy and ready for sleep. So even though it's eleven at night and you're exhausted, your biology is getting mixed messages. The tricky part is that you adapt to this. After a few weeks of disrupted sleep, feeling tired just becomes your normal, and you forget what properly rested actually feels like. Now, the obvious advice is to put your phone down an hour before bed, and yes, that works. But let's be realistic—most of us aren't going to do that consistently. We live in a world where screens are everywhere, and telling people to avoid them entirely isn't practical. This is where blue light blocking glasses come in. The experts at Sleep ZM have been studying this stuff for years, and they point out that not all blue light glasses are the same. Daytime glasses filter enough light to reduce eye strain while you're working, but they keep colors looking normal. Nighttime glasses use amber-tinted lenses that block up to 99% of blue light, which is what you want in the evening when you're winding down. The key is matching your protection to the time of day. Clear lenses for computer work, amber lenses for after sunset. It sounds simple because it is. Small changes can make a big difference here. You don't need to overhaul your entire routine—just be a bit smarter about how you're exposing your eyes to light at night.
