More research is needed scientifically quantify the benefits of blue light-blocking glasses. Most people have heard of blue light glasses by now, but they’re still a relatively new product. Blue light blocking glasses substantially increase contrast and can make looking at electronic screens much more comfortable, especially over long periods of time. Computer screens and other digital devices give off significant amounts of diffuse blue light, which reduces contrast and contributes to digital eye strain. Because it’s emitted as shorter (smaller) waves, it scatters in all directions and is hard to focus. Blue light filtering lenses help protect against high-intensity blue light, which is potentially hazardous to the eye.īlue light has a shorter wavelength than other visible light colors. Our eyes don’t block blue light very well on their own. Blue LED lighting is incredibly versatile, energy-efficient, and environmentally friendly.īlue light becomes a problem when we get too much of it and are exposed to it at the wrong times, thanks to digital screens and artificial lighting. The sun is the biggest source of blue light, and being exposed to blue light waves improves attention, reaction times, and mood during daylight hours. Wisconsin Vision offers blue light filtering glasses for men, women, and kids, with or without a prescription.īlue light isn’t always a bad thing. It’s not the lens itself that blocks blue light, but a special coating applied during the lens finishing process. Good news: symptoms of eye fatigue from digital displays are easily treatable with blue light lenses.īlue light glasses have lenses that block or filter blue light. However, if you're experiencing any discomfort or eye strain, you should take a break from wearing them.Digital eye fatigue is so common many people don’t realize their headaches, dry eyes or blurred vision might stem from screen time. In fact, it's recommended that you wear them as much as possible to reduce the effects of blue light exposure. It's safe to wear blue light glasses every day. Is it OK to wear blue light glasses everyday? So if you're looking for a way to reduce the effects of blue light exposure, blue light glasses may be the perfect solution. They can help reduce eye strain, headaches, and sleeping difficulty. What are benefits of blue light glasses?īlue light blocking glasses are a great way to protect your eyes from the harmful effects of blue light. Usually, blue light lenses have a slightly yellow tint to counterbalance the blue light, but you are unlikely to notice this. This is done by filtering blue light rays to help prevent them from entering your eye and causing potential damage. How do blue light blocking glasses work?īlue light glasses are specifically designed to reduce the amount of blue light that reaches the eye from computers or somewhere else. However, some experts have suggested that too much exposure to blue light has the potential to damage the light-sensitive cells in the retina. At the moment, the scientific community hasn’t reached a full conclusion on how blue light affects the eyes since more research needs to be done. This means that almost all visible blue light rays can pass through the cornea and lens to the retina. FAQ About Blue Light Glasses How does blue light affect us?īlue light has a short wavelength making it easy for it to penetrate the eyes.
