MacBook Pro 16 screen protector: Most people are aware that sunlight contains visible light rays and also invisible ultraviolet rays that can tan or burn the skin. But what many don’t know is that the visible light emitted by the sun comprises a range of different-colored light rays that contain different amounts of energy.
Artificial blue light, the kind associated with LED and screen-based OLED illumination, operates on a different level of the spectrum, in the 380–500 nanometer range. The 415–455 nanometer range is the most harmful — what’s called high-energy visible light, or HEV — and it’s where digital blue light from laptops, tablets and mobile phones operate. Sunglasses are designed to block light in this range — as are welding helmets! But the tech industry has been slow to adjust. “Apple for sure doesn’t build to that standard,” Bill pointed out.
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 a few extra details at Blue light filter.

Many people are affected by computer vision syndrome, which is eyestrain from fixing your gaze at the network for a long time. It can also result in pains in the shoulders, neck, back, and neck. Keep your computer monitor at least 4 – 8 inches below the eye level. Take a break and look away from the computer screen every 15 minutes.
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.
