Amazing eyecare tempered glass screen protectors: On the other end of the visible light spectrum, blue light rays with the shortest wavelengths (and highest energy) are sometimes called blue-violet or violet light. This is why the invisible electromagnetic rays just beyond the visible light spectrum are called ultraviolet (UV) radiation.

High energy light is crucial to everyday life. We get high energy visible light from the sun, and it helps us regulate our sleeping patterns. During the daytime, the light that comes into our eyes releases enzymes in the morning, bringing melatonin levels down and helping us wake up. A consistent cycle of rest and wake, regulated by melatonin, comprises our circadian rhythm. This cycle can easily be disrupted. Fly to another country, or stay up too late, and the rhythm can change. Shift into blue light use, and disruption can easily occur. Artificial blue light before bed reduces the amount of melatonin being released in the body. Too little melatonin, too late, can prevent sleep and lead to exhaustion.

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. See additional 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.

The light sources for this therapy emit bright white light that contains a significant amount of HEV blue light rays. Also, blue light is very important in regulating circadian rhythm — the body’s natural wakefulness and sleep cycle. Exposure to blue light during daytime hours helps maintain a healthful circadian rhythm. But too much blue light late at night (reading a novel on a tablet computer or e-reader at bedtime, for example) can disrupt this cycle, potentially causing sleepless nights and daytime fatigue. If you are using your phone constantly — especially if you use it primarily for texting, e-mailing and web browsing — a convenient way to reduce your blue light exposure is to use a blue light filter. Digital electronic devices emit blue light that can cause eye strain and may lead to eye problems over time. These filters are available for smartphones, tablets, and computer screens and prevent significant amounts of blue light emitted from these devices from reaching your eyes without affecting the visibility of the display. Some are made with thin tempered glass that also protects your device’s screen from scratches.

Tempered glass screen prtector (aslo called Toughened glass screen protector) is a type of safety glass screen cover processed by controlled thermal or chemical treatments to increase its strength compared with normal glass screen protector. Tempering craft puts the outer surfaces into compression and the inner surfaces into tension.Tempered glass screen prtector is 5 to 10 times more stronger than normal glass screen protector. Tempered glass screen protector is usually made of multi-layered structure, 3-5 layer is most frequently on market.(PERFECTSIGHT best eye care tempered glass screen protectors for iPhone, iPad, MacBook even is up to 11 layer).
