Is Blue Light Filter Lens Good for Eyes?

Blue Light Filter Lens The time we spend in front of a mobile or laptop screen has increased tremendously in the past decade. 10 years ago, hardly anyone had a laptop, smartphones were new, and our exposure to screens was restricted to TV. By that time, everyone knew watching TV for more than 2 hours a day was harmful to their eyes. However, we have seen tremendous technological advancements in these 10 years. Now even our free time is spent watching a movie or binge-watching a TV series. 

All in all, an average adult now spends over 6 hours a day in front of a screen. These screens emit blue light, which is harmful to our eyes. People have started taking cognizance of this fact wearing computer glasses. These glasses have blue cut lenses that reduce blue light’s on the eyes. To under how this is achieved, let’s understand some fundamentals about blue light. 

Blue Light: What is it? 

The visible colour light spectrum comprises seven colours: violet, indigo, blue, green, yellow, orange, and red. The visible colour light spectrum contains seven colours: violet, indigo, blue, green, yellow, orange, and red A light’s wavelength and energy fluctuate as it moves from one end of the spectrum to the other end of the spectrum. As a result, red light has the longest wavelengths and the lowest energy of all the colours. Violet is located at the other end of the spectrum, where it has the shortest wavelengths and the greatest amount of energy. Its wavelengths are lengthy and its energy is high because blue is located at the violet end of the spectrum. By coincidence, the same blue light released by our computers, smartphones, and tablets is also emitted by the screens on our devices. As a result, staring at a computer screen for extended periods of time puts strain on our eyes, which can be hazardous in the long run. Consistent exposure to blue light raises the possibility of developing eye-related illnesses.

What can be done about the Blue Light? 

The easy way out is to significantly reduce the numbers of hours you spend in front of a screen. It should not be more than 2 hours a day. However, this is now an impossible task because the world we live in is becoming more digital every day. Even our free time is spent catching up on movies and TV series. This is in addition to the time we spend on our laptops at the office. Therefore, since nothing can be done about reducing our exposure to blue light, we can take other steps to deal with the problem. The most popular way is to wear blue light filter glasses. Also known as computer glasses, they have blue cut lenses that prevent the blue light from reaching your eyes. 

Is a blue light filter lens good for your eyes? 

Blue light filter lenses are good for your eyes, and not only when you are sitting in front a screen. Screens are not the only sources of blue light. The same light is also emitted by the sun, and it can be equally stressful. Blue light filter glasses significantly reduce the impact of blue light on our eyes. This, in return, reduces the digital eye strain and our eyes stay healthy.
