Does it seem like everyone is talking about blue light these days? There’s a reason for it. If you’re reading this on one of your screens (smartphone, laptop, tablet), you’re exposing your eyes to blue light now, though that might be a bit simplified. As we spend more time staring at monitors, iPads, and smartphones, we increase the amount of blue light we’re exposed to — and that’s where blue light filtering glasses will help. What is blue light anyway? For starters, blue light doesn’t actually appear blue to the naked eye. Blue light is the portion of the visible light spectrum with the shortest wavelengths (400 to 500 nanometers or nm) and with the highest energy, hence it is often referred to as high-energy visible (HEV) light. Blue light exposure may increase the risk of macular degeneration and does contribute to digital eye strain. What does blue light do to your eyes? Blue light is everywhere, and it can throw off our natural body clocks. We get constant exposure to blue light from ambient sunlight, computer screens, tablets and mobile phones. If a person is exposed to blue light for long periods of time during the night, blue light makes it more difficult for us to fall asleep at night and wake up in the morning. How do blue light eyeglasses work? Blue light lenses filter out blue light by blocking the transmission of a specific segment or range of wavelengths. The lenses are designed to help reduce the occurrence of digital eye strain and avoid circadian rhythm cycle disruption, affecting sleep and overall well-being. The blue light lenses are usually a pale yellow tint (if you can see any color at all) and block harmful blue light, while modulating the wavelength impacting circadian rhythm. If you haven't worn blue light blocking glasses before, you may need an adjustable period of 2-3days.During this adjusting period you may experience discomfort.Just keep it, and you will find how you love it when you facing digital screen for a long time.No eye fatigue, no headache.
