Blue light filter: Visible light is much more complex than you might think. Stepping outdoors into sunlight; flipping on a wall switch indoors; turning on your computer, phone or other digital device — all of these things result in your eyes being exposed to a variety of visible (and sometimes invisible) light rays that can have a range of effects.

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 even more details on What is blue light filter.

Eye tip: This one should come as no surprise – the food we put in our bodies plays a vital role in our health. You want to be sure you’re eating foods with plenty of nutrients including omega-3 fatty acids, Zinc, Vitamins A, C, & E. Here are some of the foods that contain these vision-enhancing nutrients: Omega-3 Fatty Acids, which can help to reduce the symptoms of dry eye, can be found in several natural food sources including salmon, mackerel, tuna, walnuts, chia seeds and tofu.

The amount of HEV light these devices emit is only a fraction of that emitted by the sun. But the amount of time people spend using these devices and the proximity of these screens to the user’s face have many eye doctors and other health care professionals concerned about possible long-term effects of blue light on eye health. The short-wavelength, high-energy light rays on the blue end of the visible light spectrum scatter more easily than other visible light rays when they strike air and water molecules in the atmosphere. The higher degree of scattering of these rays is what makes a cloudless sky look blue.
