What are blue light glasses, and what do they do?
Well, if you’ve been wondering a similar thing, let us tell you that these glasses are your best bet when it comes to keeping you away from hazardous blue-violet light rays.
These lights are generally emitted from digital sources like television screens and mobile, and even your computer.
Even if you don’t spend your days staring at screens, you’re familiar with at least part of that description. If this is the case, you might think about investing in a set of blue light glasses. These genius glasses claim to provide relief from the symptoms that come with excessive screen time.
How Does Blue Light Affect Your Eyes?
The light spectrum visible to the naked eyes has colors ranging from blue to red! Blue light is at the extreme edge of the spectrum, near UV light, which is invisible. “High-energy visible light” refers to blue light (HEV). It has a shorter wavelength than hues closer to the red end of the spectrum. Thus it reaches our eyes at a greater frequency and with higher energy.
Extensive blue light exposure from our gadgets is currently being investigated to see if it might produce retinal alterations similar to those seen in Age-Related Macular Degeneration caused by light from the sun. Blue light is known to induce sleep cycle abnormalities, headaches, and eye strain in humans.
When Should You Actually Wear Blue Light Glasses?
The fact is that the amount of screen time we spend each day is an issue for which there is no simple answer. Experts suggest that nearly 80% of the UK population considers checking their mobile phone in the first hour that they wake up in the morning.
Screens have become an unavoidable aspect of our life. Screens have evolved into a source of information, entertainment, communication, social interaction, and a job tool. Although limiting your screen time may be beneficial, many people find it challenging to do so.
Now, here are some reasons why you might need blue light glasses:
- Increased Eye Strain:
Suppose your eyes feel dry, weary, or strained after using your device for an extended period of time. In that case, you may be suffering from computer vision syndrome, also known as digital eye strain.
The blue light exposure, frequent flickering, the glare of your LED screens, lowered blink rate, and the need to retain your eye’s concentration for an extended amount of time all contribute to this problem.
- Sudden Headache:
One of the most unpleasant side effects of damaging blue light is headaches. If you’ve spent a lot of time in front of a screen, you may not even recognize that the headache is a symptom.
Long periods of time spent looking at anything can create headaches, and blue light exacerbates the problem. Reading a book can induce eye strain, but reading on a screen with light causes it much more quickly.
- Ease Sleeping:
Blue light might also make it difficult to get a good night’s sleep. What effect does blue light have on your sleep cycle? The sun’s natural blue light tells your body when it’s time to sleep and when it’s time to get up.
Blue light, in particular, instructs your brain to cease generating melatonin, a sleep-inducing hormone. When you use screens close to bedtime, your brain becomes confused. Melatonin synthesis should be switched on now that nightfall has arrived, but displays tell your brain to turn it off.
Now that you have an idea of the different perks that a blue light glass adds to your everyday life, chances are you might want to know the different ways to select them.
Well, it’s simple, given their massive boom, blue light glasses have long been the center of attention by many. This has also given several businesses with scope to come up with fakes.
This makes it very hard for users to spot the right glasses from hundreds of brands. Therefore, in the following section, we have discussed some tips and tricks to get things done.
Tips To Find The Perfect Blue Light Glasses
When it comes to blue light glasses, it’s the color of the lens that actually plays a great role in blocking the harmful rays. To give you an idea, we have listed the different colors of shades and how they can be helpful.
- Clear lenses are known to reduce up to 40% of blue light! They are excellent for reducing digital eye strain and enhancing daily energy and attention.
People who need to see genuine colors on screens and/or wear uniforms while maintaining their circadian cycles may find clear glasses to be of particular use.
- Up to 75% of blue light is blocked by yellow lenses. They essentially accomplish the same thing as clear lenses, but they could be more useful because they block nearly twice as much unwanted light.
Besides, since not every blue light is “bad,” the yellow lenses help your eyes in catching the healthy rays. They do so by retaining some of the rays.
- Blue light is often blocked by orange lenses by 98–99%. Orange lenses were used in the first blue-blocking eyewear ever developed for NASA’s space program. These colored lenses are perhaps the most common ones available, however, they aren’t as useful as many would believe. The blue light spectrum is too blocked by orange lenses during the day and under blocked by green and violet light at night.
Keep in mind that you require varying levels of blue light during the day and essentially no light at night in order to maintain your biological cycles in sync with the sun’s natural rise and set. (It doesn’t matter if you spent $100 or $11 on a set of orange lenses; they are ineffective compared to alternative solutions.)
- Green, blue, and violet light can be completely blocked by red lenses. Each night, as the sun sinks below the horizon, warm hues fill the sky until it is entirely black. Even if you leave the lights on in the hours before night, red lenses provide the same effect by virtually dampening the illumination.
However, not all red lenses are created equal. Since each of these light spectrums has been proved to interfere with sleep, you should try to select lenses that filter as much blue, green, & violet light as you can.
