If youíre reading this, you may already know all about the pair of blue light blocking and how they work. Pair of blue light blocking glasses, more popularly known as blue light protection, prevent blue light from entering your eye. They usually do this by reflecting any blue light that falls onto the glasses. Other types of blue light protection glasses do not use reflective coatings. Instead, they filter out the blue light by not letting it pass through the glasses.††
Blue light is light with the highest frequency in the visible light section of the electromagnetic spectrum. Blue light is present almost everywhere. It is present in sunlight, emitted from LEDs, CFLs and all kinds of screens, including television, laptops, smartphones, desktops, and tablets.
Interestingly enough, and blue light from the sun plays a crucial role in regulating our sleep cycles. This means that not all blue light is harmful. If this is the case, then why are blue light blocking glasses recommended by opticians and optometrists everywhere? And why should you get them for yourself? These are some questions we try to answer in this blog.
Blue light causes retinal degradation. Does it?
One of the first things your optician would have told you about blue light blocking glasses is how these protect your retina from any damage. It is said that unlike ultraviolet light, blue light can easily pass through the lens of the eye. And after passing through the lens, blue light reaches the retina where it can damage the cells of retinal pigment epithelium because these absorb blue light. Although research has shown that prolonged exposure to high-intensity blue light can cause retinal damage, the intensity emitted from screens is nowhere near the intensity used in studies. So, blue light causes little damage to the retina. The chances of age-related macular degeneration due to blue light are very little when compared to other factors like smoking.
Blue light disrupts your sleep!
The amount of blue light youíre exposed to can disrupt your sleep cycle to a great extent. This is because blue light falling on the retina stimulates the pineal gland in your brain to produce a hormone called melatonin. Melatonin, more commonly known as the sleep hormone, stimulates your body, not allowing you to sleep and consequently disrupting your circadian rhythm. In other words, blue light can stimulate your body to stay awake and degrade the quality of your sleep. This is a major reason why blue light blocking glasses are a must if you are working on a computer screen all day long.
Can blue light blocking glasses reduce Digital Eye Strain?
Digital Eye Strain, or Computer Vision Syndrome (CVS), refers to headaches, nausea, and eye strain caused due to long screen times. And the effect blue light blocking glasses have on relieving the symptoms of CVS varies from person to person.
Will blue light blocking glasses work for me?
This question does not have a straightforward answer. The effectiveness of blue light blocking glasses depends on various things. Some people experience great relief in headaches and eye strain after wearing eyeglasses, while others, not so much. How blue light protection glasses work for you depends on the time you spend in front of a screen.
Although if you want a pair of blue light blocking glasses to work effectively for you, you should follow the 20-20-20 rule, use blue light filters for your computer and smartphone screens.
All in all, if you want a quality sleep every night and also relieve yourself of symptoms of digital eye strain, you should get a pair of blue light glasses from Specscart. With a wide choice of glasses frames, Specscart makes buying glasses easier and better.
