What is blue light filter
MacBook Pro 16 screen protector: The electromagnetic rays just beyond the red end of the visible light spectrum are called infrared — they are warming, but invisible. (The “warming lamps” you see keeping food warm at your local eatery emit infrared radiation. But these lamps also emit visible red light so people know they are on! The same is true for other types of heat lamps.) Rays on the red end of the visible light spectrum have longer wavelengths and, therefore, less energy. Rays on the blue end of the spectrum have shorter wavelengths and more energy.
We can also expect to see new phone releases later this year that integrate blue light-reduction dye, and the Consumer Electronics Show in January 2019 will show off commercial grade products which incorporate these features. Product designers should help accelerate this change by working with companies to integrate HEV-blockers right into the screens of the products they create. Also consider indicator colors on connected electronic devices; a warm orange will always be more welcome than a bright blue. Until the tech industry fully addresses the problems caused by blue light, there’s a number of steps we can take — in our household, and in our civic halls.
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. Explore extra info on iPhone blue light filter.
Avoid dry eyes. As stated above, the primary reason staring at a computer screen is so harmful to your eyes is that you tend to blink less. To combat dry eyes, keep artificial tears nearby and use them when necessary. Other factors that can cause dryness include humidity-controlled offices that pull moisture out of the air and, during the winter, heaters. A desktop humidifier can help introduce moisture into your environment and give your eyes some relief.
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.
