About Blue Light Filter Glasses

15th of January, 2021 — The pandemic of COVID-19 has benefited the blue light glasses business.

People in lockdown are purchasing more blue light glasses as they spend more time looking at laptops and other digital screens, despite the absence of clear proof that the glasses relieve eyestrain or protect against the impacts of blue light.

According to the optical maker, sales of the blue-light-blocking gadget Blokz have climbed by 60% annually for the past two years, with about 2 million pairs sold in 2020 alone. The global market for blue light eyewear is expected to expand from $19 million in 2020 to $28 million by 2024.

What is blue light?

There is a lot of blue light around. It may be found in the sun's beams and is released by fluorescent lights and electronic device screens.

All hues of light may be found in the sun, including red, orange, green, and blue. Each hue emits a different amount of energy. The wavelengths of red light, for example, are longer and have less energy. Blue light, on the other hand, has shorter wavelengths and a higher energy level.

Why should you use blue light glasses?

Work and social life are increasingly centered on staring at a screen for several hours each day. Consider wearing blue light protection to counteract the effects of too much blue light exposure. Here are five reasons why these glasses may be beneficial to you

1. Reducing Headaches

• Light, particularly blue light, can aggravate headache discomfort and induce migraines. Blue light blocking glasses may help to minimize migraine episodes as well as headaches and suffering.

2. For Better Sleep

• Similarly to taking a stroll outside in the sunlight, spending time in front of a screen before bed might help you feel alert. Short wavelengths delay the production of melatonin, a sleep-inducing hormone that begins to circulate in your body a few hours before bedtime. Using a tablet or other screen before bed might cause this release to be delayed, making it more difficult to fall asleep quickly. If you can't switch off your smartphone an hour or two before bedtime, as recommended by sleep experts, blue light spectacles might help you sleep better.

3. Eye illnesses are less likely to occur

• Your cornea and lens do an excellent job of preventing UV rays from reaching your retina. They cannot, however, block blue light. Macular degeneration is a primary cause of blindness, and damage to the retina might raise your chance of having it. Blue light can enter your retina, causing symptoms similar to macular degeneration and perhaps increasing your risk of cataracts. Wearing protective gear can help you avoid this.

4. Less strain on the eyes

• You may feel anxious from staring at a screen all day, or you may develop eye and muscular strain. Ergonomic changes can help alleviate the muscular problems that come from sitting at a computer all day and staring at a screen. Eye strain can be reduced by wearing blue light blocking glasses. Blue light can make it difficult to concentrate on a screen, causing your eyes to strain. Blue light glasses improve contrast on your screen, making it simpler to focus and reducing eye strain as a result.
