A general answer to the question “What are blue light blocking glasses?” is that they are protective eyewear that helps minimize the adverse effects of blue lights. But in order to better understand what the product really is, let us take a look at some of the facts about it.
Do your eyes feel fatigued after staring at a screen all day? Well, there is a reason for that.
The human eyes are not that suited for blocking blue light rays. Our eyes have evolved according to the environment and although there is a blue light in our main source of light, i.e. sunlight, it is nowhere near as much as we’re exposed to these days.
Due to the advent of digital screens, blue lights have proliferated to the point that they have started affecting our eyes. The thing is, our eyes are better suited to blocking UV rays since we’ve been exposed to UV rays since the dawn of time.
If you’re wondering, perpetual exposure to sunlight had something to do with it.
Let us first look into how blue light affects our lives.
How Blue Light Affects Our Sleep
Exposure to blue light through natural sources such as sunlight has positive effects. The thing is, blue light itself is not bad for us. Blue light boosts our energy levels throughout the day and keep us alert and regulates our mood.
However, in a completely natural environment, there wouldn’t be any sources of blue light after the sunset, which helps our internal systems to get ready for bed. Exposure to blue light affects our melatonin levels, which is a hormone that controls our sleep cycle.
On average, the sleeping time has decreased over the last two decades. It is no coincidence that the phenomenon coincided with the widespread adoption of digital screens in our life. Staring at a screen increases our alertness and inhibits our ability to sleep.
How Blue Light Affects Our Eyes
According to some studies, chronic exposure to blue light represents an increased risk of developing age-related macular degeneration. Unfortunately, experts still have yet to research the impact of blue light from LED, as LED lighting is still a relatively new technology.
However, there is no doubt as to the deleterious effects of blue light have on our eye health. Since we are the first generation with digital screens literally everywhere, even in our pockets, the end result of such blue light exposure is yet to be seen.
Aside from the long-term effects of blue light exposure, there are some short-term effects as well. Using most of our waking hours in front of a screen can cause eye fatigues and lead to chronic headaches.
In order to counteract the immediate and adverse effects, some recommend people to wear blue light blocking glasses or computer glasses.
Let’s take a look at what blue light blocking glasses are and why they are important for our eye health and general wellbeing.
What are Blue Light Blocking Glasses: A Detailed Look
Blue light blocking glasses evolved from the blue light screen filters. They are also known as computer glasses. These glasses are used specifically when sitting in front of a computer screen. They help minimize exposure to blue lights, which have become ubiquitous in modern societies.
These glasses are specially designed to reduce glare from a screen and maximize your ability to see through the lenses clearly. They make it easier to look at a screen for an extended period of time without straining your eyes.
The following are the two main features of blue light blocking glasses:
These special anti-reflective coatings significantly reduce the glare of screen and other sources of light. One important thing to put in mind is that an anti-glare coating tends to wear faster than the lenses since the coating technology is still improving. So you should replace your lenses even if your eyesight hasn’t changed.
Special Color Tint:
Computer glasses also have an unmistakable tint—mostly yellow. The tinted lenses are designed to increase the contacts from the screen and filter out the harsh blue light coming from the screen. This makes it easy for the eyes to do what they do, allows muscles in the eyes to relax, and minimizes the potential for eye strain.
Now we should be able to give a better answer to our initial question, “What are blue light blocking glasses?” They are specially designed glasses that will not only mitigate the potential for long-term eye harm but will also give you the required respite from screen-induced headaches.
They are products wherein manufacturers have incorporated special features that are capable of reducing exposure to blue light. They can be worn with or without any prescriptions.
