Blue light blocking glasses: Without getting into complicated physics, there is an inverse relationship between the wavelength of light rays and the amount of energy they contain. Light rays that have relatively long wavelengths contain less energy, and those with short wavelengths have more energy.
Fortunately, many device companies are aware of the health risks from blue light, and are implementing solutions. Bill James’ works at Healthe, Healthe, which develops a dye that mitigates blue light and can be layered on glass or clear adhesive. They’re partnering with glass companies that produce the majority of glass for automotive applications, meaning we should see commercial applications of blue-light filtering technology in our own devices in the near future. (You can also buy blue-filter covers for your laptop, mobile phone and VR goggles at the Healthe webstore.)
Blue light is a range of the visible light spectrum, defined as having a wavelength between 400-495 nm. This short wavelength means that blue light is a type of HEV (high-energy visible light), defined as having a wavelength between 400 and 450 nm. Because the blue/violet band of the visible spectrum has a particularly high frequency. Blue light isn’t some special form of light that only comes from computers and LED lights – it’s actually all around us. In fact, sunlight is the main source of blue light. When you walk outside during the daytime, you’re exposed to blue light. Discover extra details on Blue light filter iPad.
Reduce glare. Glass screens can produce glare that can aggravate the eye. If you don’t have control over the lighting in your environment, try using a matte screen filter. Follow the 20-20-20 Rule. Every 20 minutes, give your eyes a break by looking at an object 20 feet away for 20 seconds. This allows your eyes to relax. Limit devices before bed. Research shows that the blue light from your phone and other screens may affect the body’s natural wake and sleep cycle. During the day, blue light wakes us up and stimulates us. It does the same thing at night, which makes it harder to get to sleep. Limit screen time one to two hours before bedtime. Use nighttime settings on devices and computers that minimize blue light exposure.
If you have cataracts and are about to have cataract surgery, ask your surgeon what type of intraocular lens (IOL) will be used to replace your cloudy natural lens, and how much blue light protection the IOL provides. After cataract surgery you might benefit from eyeglasses that have lenses with a special blue light filter — especially if you spend long hours in front of a computer screen or using other digital devices. So, is all blue light bad for you? Why not block all blue light, all the time? Bad idea. It’s well documented that some blue light exposure is essential for good health. Research has shown that high-energy visible light boosts alertness, helps memory and cognitive function and elevates mood. In fact, something called light therapy is used to treat seasonal affective disorder (SAD) — a type of depression that’s related to changes in seasons, with symptoms usually beginning in the fall and continuing through winter.
What PERFECTSIGHT eye care screen protectors and eyeglasses do? PERFESIGHT eye care protectors (HD Clear Medical Edition or Matte Anti Glare Medical Edition) could blocks more than 55% of the blue light into eyes especially in about 450nm wavelength and reduce the damage of blue light to the eyes, really to be best blue light filter for deigital device. PERFESIGHT blue light blocking glasses could filter about 70% of the blue light from your phone,tablet, computer’ screen. Eye Care screen protectors tested by specially AMERICAN SOLAR LIGHT.
