What is Blue Light and why we need to protect yourselves from it?

Blue light is not a bad thing. Did you know that you can find it everywhere, even in sunlight! According to researchers, the blue wavelengths, just before Ultraviolet Light (UV) during daylight hours, have umpteen benefits like help you stay upbeat, boost reaction time and improve attention.

But now you are constantly exposed to the light coming off our electronic devices, most of it is blue light. Exposing yourself to too much blue light, especially at night, suppresses the secretion of a hormone called melatonin which is the central regulator of the circadian rhythm, which controls your daily sleep-wake cycle.

This interferes with your natural tendency to fall asleep at night and makes it almost twice as hard to do so. Hence, it is important to limit your screen time to allow you to have better sleep cycles.

For many working professionals, it is difficult to limit the time you spend in front of screens hence it becomes essential for you to protect yourself as not only does a lack of sleep affects productivity, its long-term effects are much more severe.

You can find filters in the lenses of blue light blocking glasses which help to absorb or block blue light from getting through. This is helpful if you are looking at an electronic screen, especially at night, blue light blocking glasses will protect your eyes and help you sleep better. During the day, they will also reduce the amount of blue light you are exposed to, hence reducing eye strain.

Using blue light blocking glasses is not only useful for professionals who spend their day in front of laptops or computers, but also for children. Everyone experiences different levels of exposure to blue light, but a risk common to all is excessive exposure to blue light. So even children, who are in their formative years, can benefit from the use of blue light blocking glasses.

They do not affect general vision

High quality blue light protecting glasses not only offer solid protection against the ill effects of blue light but do not hamper your everyday tasks.

This does not affect the quality of the visual which you are seeing be it on television or your laptop, allowing you to perceive true colour tones.

How to pick an effective Blue Light Blocking Glass

There are many eyeglasses online which say they protect against blue light, but most fail in reality. A few things to look for when picking blue light protecting glasses include:

1. Make sure they are scientifically certified. This is an indication that the eyeglasses have undergone laboratory testing.
2. Avoid getting glasses with clear lenses, amber lenses do a better job in effectively blocking out blue light and letting through shorter, less harmful wavelengths of light compared to clear glasses.
3. Anti-glare and Anti-reflective: This type of glasses come with features which lessen the strain on eyes that comes from spending time in front of screens. Anti-glare and anti-reflective glasses filter the blue light wavelengths and cut down overexertion and strain which occurs in light rich environments.

Some final points to keep in mind include making sure they are comfortable and come with a generous warranty. As you wear them for a major chunk of your day, it is important that they are comfortable to wear. Also, since they will be in constant use, they run a high risk of falling down, being stepped on or other scratches and cracks. Investing in blue light protecting glasses is an investment worth making. A high-quality pair of blue light glasses will go a long way in reducing your daily blue light consumption, thereby helping you sleep better and protect your overall health.
