Blue light glasses is a good option to filter out harmful blue ray. Blue light is one of the visible light of the light spectrum. Blue light has a short frequency, thus creates a higher measure of vitality. Studies propose that, after some time, introduction to the blue finish of the light range could cause genuine long term harm to your eyes. Blue light has a wavelength of between approximately 380nm and 500nm; making it one of the shortest, highest-energy wavelengths.
The eye doesn’t prevent the blue light from entering. UV beams are blocked by the cornea and lens from coming to the rear of the eye (the retina). Blue light goes through these structures and can reach at the retina.
Blue light may increase the danger of macular degeneration and contributes to digital eye strain. Being excessively near your screen is not good. People tends to strain the eye muscles when focusing at near .
Short-wavelength, high energy blue light scatters more easily than other visible light, it is not as easily focused. When you’re looking at computer screens and other digital devices that emit significant amounts of blue light, this unfocused visual reduces contrast and can contribute to digital eye strain.
Research has shown that lenses that block blue light with wavelengths less than 450 nm (blue-violet light) increase contrast significantly. Therefore, computer glasses with yellow-tinted lenses may increase comfort when viewing digital devices for extended periods of time.
Long hour screen time caused lost in rest pattern, since blue light influences the level of melatonin – the rest hormone in our body. It diminished light around evening time, stops the body to create rest hormones like melatonin. Blue light upsets these signs and less melatonin is produced.
There is abundant evidence showing that blue light affects our bodies in creating melatonin. If you use screens long after sunset, these blue light glasses might help to stop you from staying up later than you want.
In short, blue light separating glasses are an incredible method to battle the eye strain and restlessness that accompany unreasonable screen time.

1.What does blue light do to your eyes?
Exposure to the blue light will increase the risk of macular degeneration. Blue light penetrates the entire way into retina and many experiments have shown that too much exposure to blue light will damage the retina’s light sensitive cells.
2. Is blue light from phones harmful?
Yes, blue light from our gadgets are harmful and can lead to macular degeneration.
3. Is it bad to wear blue light glasses all day?
If spending long hours every day in front of screens then blue light glasses can help to avoid eye strain and protect the eyes. Blue light damage is cumulative so if it does not hurt the eyes now but it will later.
4. What are blue light glasses?
These glasses have filters in the lenses that block or absorb blue light, and in some cases UV light, from getting through. In short, when these glasses are worn when looking at a screen, especially after dark, they can help reduce exposure to blue light waves that can keep you awake and also reduce eye strain.
5. Is it necessary to wear blue light blocking glasses?
It really depends on do you want or need to look at your phone after dark and whether having trouble falling asleep after using the either the phone or computer.
