Several of my office colleagues wear blue light blocking glasses to their workplace, and I have always wondered why. My curiosity led me to a world of fantastic facts related to the blue light, how it can affect our health, and why it is essential to wear the glasses to block the light. Therefore, here I am, writing this blog to share some important facts with you. I have covered the topic right from scratch to help people out there who don’t really have any idea about the blue light, just like me in the past.
What is the hype about the blue light?
The visible light falls within the wavelength of 400 to 760nm. On the other hand, high energy visible light falls within the range of 400 to 500 nm. This high energy visible light is what we know as the blue light because the blue light consists of a high spectrum range.
We are being exposed to artificial blue light through a variety of sources in our daily lives. Some of the most common sources include mobile phones, televisions, and other digital display screens. This blue light tends to disrupt the circadian rhythm of an individual and also causes other health problems. Thus, it is crucial for everyone who has to work in front of laptops, to wear blue light filter glasses while staring at the screen.
How Do Blue Light Blocking Glasses Actually Work?
Blue light blocking glasses have a special filter in their lenses that absorb or block a certain percentage of blue light from your artificial source. Therefore, using these glasses can reduce the amount of blue light you will be exposed to. As a result, you can steer clear of eye irritation or other health issues.
Some of the blue light filter glasses can also help you take care of the eye strain. Eye strains usually occur due to constant working in front of laptops and mobile phones. Do you work night shifts? In that case, staring at the screen of your laptop can make you feel way too sleepy or cause a headache. In such situations, you can try out the special glasses that block the blue light for you.
Blue light blocking glasses have orange-colored lenses: why?
Most of these special glasses consist of orange or yellow colored lenses. These glasses have a slight tint on their lenses because of the purpose that they serve. The slight hue filters out the HEV light frequencies. Thus, if a higher percentage of blue light is being emitted, the lenses will appear a little bit more orange.
I would recommend everyone looks for a pair of glasses that have a clear lens. It is because our body needs a certain amount of blue light to remain awake. Clearer lenses will balance our exposure to blue light easily. You can work and sleep comfortably and stay away from being a victim to eye problems. If you have any other queries related to blue light or glasses, you can talk to an ophthalmologist.
