How Does Blue Light Affect Our Sleep
There are a lot of factors in our busy lives that can affect our sleep. Obvious things like stress over a presentation or an exam, worrying about money, babies crying or cats throwing up hairballs can cause sleeplessness or interrupt a good nights rest. What we may not realize is that exposure to blue light can be a sneaky cause as well. Blue light suppresses the bodys secretion of melatonin, a hormone that regulates sleep and wakefulness. Though blue light is present in the suns rays during the day, it is less pronounced around dusk, which is why sunsets tend to appear red. The lack of blue light in the evening allows the body to produce melatonin freely, signaling that it is time to prepare for sleep. Exposure to blue light from electronic devices or artificial lighting after the sun has gone down can disrupt our circadian rhythm, making it harder to fall asleep or get a good nights rest.

What Is Blue Light And Do You Need To Block It
Imagine light passing through a prism, which fans it out into the colors of the rainbow. Each color you see is part of the visible light spectrum, which is defined by wavelengths. Shorter wavelengths generally become more harmful as they decrease, which is why many people want to block too much blue and violet light from reaching their eyes. However, its not a good idea to banish blue light completely. Its found in every light source, including sunlight, and is known to boost your attention and mood. Long-term effects on eye health are unclear, but some studies have shown that rat retina cells die when exposed to extreme levels of blue light.
Blue light plays a major part in controlling your sleep cycle. Too much of iteven everyday levels, if you spend a lot of time in front of a screenhas proven problematic. Daylight, which contains blue light, helps tell your internal clock when its time to start the day or hit the hay. Stare at a blue-light-emitting device for too long at night, and your body might think its still daytime. Blue light, especially, has been found to suppress melatonin for about twice as long as green light. That could mean the difference between falling asleep in 30 minutes and one hour. During the day, such exposure to blue light can help keep you alert, but in the evening hours it can be potentially problematic .

What Does Blue Light Do To Your Eyes
Blue light has a short wavelength, which makes it very easy for it to penetrate the eyes. This means that almost all visible blue light rays can pass through the cornea and lens to the retina . While there is little research to support this, some experts have suggested that too much exposure to blue light has the potential to damage the light-sensitive cells in the retina. One animal study also found that blue light damage may cause phototoxic retinal damage.1
However, while it is true that digital screens do emit some blue light, research has found that the level of blue light exposure from screens is significantly lower than that from natural daylight and neither levels approach eye safety limits.2 This means that the potential blue light damage caused from digital screens is likely to be very little, if any at all.

How Do You Protect Your Eyes From Blue Light
Reducing the use of devices and lighting that emit harmful blue light rays is the most effective approach. However, many people rely on their electronic tools for work, resulting in many hours of exposure every day. Plus, it’s hard to avoid indoor LED and fluorescent lighting that contributes to blue light emissions.
Taking some preventive measures can help limit potential blue light damage. Apply the 20/20/20 rule look away from your screen every 20 minutes at a focal point 20 feet away for 20 seconds. Scheduled breaks and regular eye exams may also have limited benefits. However, the most effective way to protect your eyes, your vision, and your health from harmful blue light is with blue light filters, like those found in our blue light glasses.

Light Exposure And Sleep Quality
Light is one of the most important external factors that helps control our sleep-wake cycle.
Before the advent of electricity, humans slept and woke according to the timing of the sunrise and sunset. Sunlight is composed of a wide range of light wavelengths, including the entire visible spectrum from red to violet as well as ultraviolet and infrared wavelengths. However, blue light in the range of 446 to 477 nm has the most significant impact on the sleep-wake cycle.
When it comes to natural light from the sun, blue light is very helpful. Exposure to a healthy amount of blue light in the daytime promotes alertness and helps you sleep better at night. However, too much blue light exposure later in the evening makes it harder to fall asleep and may also contribute to poor sleep quality and morning grogginess.
Popular electronic devices such as smartphones, tablets, gaming devices, and televisions emit blue light. Blue light blocking glasses are intended to act as a barrier between you and these artificial blue light sources to prevent your late night screen time from disturbing your sleep.
