What is A Blue Light Filter?
Have you heard of a blue light filter? If not, you’re not alone. Blue light filter glasses, blue light filter for pc, and blue light filter for iPhone are new technologies on the market. The name says it all–these tools filter out blue light from your screens. By why would you want to filter out blue light and what is a blue light filter anyway? This article will go in depth into the phenomena as well as recommend a variety of blue light filters to help you determine whether a blue light filter is what you need to stay healthy this year.
A blue light filter is relatively straightforward. It’s usually a piece of plastic that is manufactured to keep blue light from being able to travel through the plastic. Sometimes the plastic has a special coating or specific tint or color to it that keeps the blue light from coming through. Products usually come in two main forms. There are films and sheets that you can put over your iPhone or computer screen to keep blue light from coming out, and you can also put on blue light glasses to filter out the light.
Why Have a Blue Light Filter
The need for a blue light filter has been growing alongside the explosion of digital screens that now make up the bulk of American life. As more and more people began using smart phones and computers for many hours a day, there have been more reports of issues with vision. Eye strain, eye twitching, and general visual fatigue increases the more time you spend staring at a screen.
In fact, there is now a diagnosable disorder called computer vision syndrome. Computer vision syndrome is a diagnosis that includes eye strain, eye pain, and other issues. It can strike both adults and children. If kids are spending hours on the computer at school or after school, they can also get diagnosed with computer vision syndrome.
Eye strain and pain due to computer use is a serious issue. Research has shown that anywhere from fifty to ninety percent of people who work at the computer screen end up with serious issues.
What Causes Computer Vision Syndrome
Carpal tunnel syndrome is a disease that has a lot of similarities to computer vision syndrome. Basically, both of the diseases are caused by repetitive motions. Just like your hands follow the same path over and over, and this causes issues in your wrists, when you’re staring at a computer screen, your eyes follow the same paths over and over. And this causes serious strain and pain in your eyes.
When you’re looking at a computer, you also need to focus and refocus constantly as you look at different tabs on your computer screen. This also causes eye strain. And every time you look at something other than the screen and then return to the computer, your eyes have to refocus.

But there’s another reason why staring at a computer screen can be so difficult for your eyes, and it’s because of the way light and your computer screens work. Computer screens emit light that causes the eye to have to work even harder to focus. Computer screens can add flicker, glare, and contrast, which can dramatically change the way you interpret visuals on the digital screens.
These issues can affect kids and adults equally, but as you age, your eyes can have even more trouble staring at screens for hours on end. This is because your ability to focus both near and far can be impacted by age, and the lenses in your eyes can become less flexible than they were previously. Because of this, your eyes can experience many difficult symptoms as you age that make it more challenging to stare at screens for hours on end.
Symptoms of Computer Vision Syndrome
The symptoms of computer vision syndrome can depend on the difficulty you’re having with your eyes. Blurred vision is one issue that arises and is the sensation of your visual field being blurry. It indicates that your eyes are having difficulty focusing. Double vision is another issue, where instead of seeing one unified image, you experience seeing the image in front of your face playing out double. Dry, red eyes are another symptom of computer vision syndrome. Dry red eyes can indicate that you are experiencing extreme fatigue in your eyes.
Another surprising symptom of computer vision syndrome are headaches, neck, and back pain. This is because your optic nerve is connected to many other nerves in your brain and neck. So when your optic nerve is under stress, you can experience pain and tension throughout your head, brain, and neck.

Why a Blue Light Filter
Because of all of the vision issues that can arise when you stare at computer screens for too long, there are many researchers and manufacturers who are developing solutions. Of course, many people are required because of their jobs to stare at computer screens throughout the day, so it’s important that we develop strategies to reduce the strain on our eyes and improve our overall eye health.
This is where a blue light filter comes in. There are a variety of factors that can increase the chance of developing computer vision syndrome due to overuse of digital screens. But one of the primary issues is the blue light that is emitted by the screens. Exposure to blue light, for one thing, can make it more difficult for you to fall asleep at night. Insomnia is actually a huge issue facing adults in the United States, with 27% of people having trouble falling asleep or staying asleep most nights. And 68% of people had trouble falling asleep at least once a week.
Scientific evidence is demonstrating that the blue light emitted by the digital screens can be a big reason why it’s difficult to fall asleep at night. Furthermore, when blue light is bright, it can cause more glare and flicker to show up on your computer screen. And as discussed earlier, this is one of the biggest contributors to computer vision syndrome and general eye strain.
For all of these reasons, using a blue light filter on your computer or cell phone screen is a great way to reduce tension and stress on your eyes. Blue light filter helps filter out blue light. There are also blue light filter glasses, blue light filter for iPhones, and blue light filters for PC.
Understanding Blue Light
To truly understand why a blue light filter could be helpful to you and how to utilize it, it’s a good idea to develop a firm understanding of how light works with your eyes in general.
Even though most light appears simply white, truly visible light includes the full range of colors in the rainbow. Sunlight, for example, contains red, orange, yellow, green, and blue light rays—and all of the colors that come in between those colors.
These light colors appear on a spectrum, with wavelengths that range from 700 nm to 380 nm. The longer the wavelength, the less energy that is contained in the light ray, and the shorter the wavelength, the more energy the light ray contains.
So where does blue and even violet light fall on this spectrum? Perhaps unsurprisingly, the wavelengths blue and violet light are shorter than the other light rays, which means that they contain more energy than the other rays.
It’s important to remember that blue light is found throughout your life. Sunlight is a primary source of blue light, and when you are outside you are being exposed to blue light. But doctors have been noticing that because of the amount of blue light that is emitted from our computer and other digital screens, it’s having an effect on our eyes and vision.
One of the reasons for this is because the eye is not very good at blocking blue light from reaching the retina. Almost all blue light that comes in contact with the eye ends up reaching the retina. There is a limit to the amount of blue light exposure to maintain healthy vision. One reason is because laboratory tests have proven that when you are exposed to more blue light you can end up damaging the light-sensitive cells in the retina. And this damage is precisely what causes macular degeneration.
And because the blue light is such a high energy light ray, it also scatters more easily when it comes in contact with the eye. This means that the eye has to work harder to focus when it is perceiving a large amount of blue light. This extra energy that your eye has to use to focus is what leads to digital eye strain and potentially even computer vision syndrome.
Finally, if you are someone at risk for cataracts, or you have recently gotten surgery for cataracts, you will want to reduce your exposure to blue light significantly. Special eyewear is developed to protect your eyes and reduce the chances of damage to the retina and overall vision loss. When you get cataract surgery, your practitioner will replace your lens, which has become cloudy, with an intraocular lens. Some of these lenses automatically include blue light filters to ensure you have great eye health for years to come. If not, you’ll want to make sure you have great blue light filter glasses to prevent any further damage to your vision.

Why Filter Out Blue Light: The Bottom Line

Of course, we are naturally exposed to blue light by the sun, and there are certainly healthy amounts of blue light that we can expose our eyes to. But because of the high energy involved in blue light, when we stare at computer or other digital screens for hours per day, there’s a higher chance that we are going to have over exposure to blue light.
This overexposure is thought to contribute to many difficult eye conditions, including eye strain, eye pain, and perhaps most damaging–trouble getting a good night’s sleep.

A Great Blue Light Filter
To determine which of the blue light filter products will be most beneficial to you, you should consider what your primary goals are. The first decision you have to make is whether to put the filter over your own eyes, using blue light filter glasses, or to put the filter over your digital screen, using a blue light filter for pc or blue light filter for your iPhone.
To make this choice, consider your personality and routine. Would you like to have complete control over how much blue light you are exposed to on any given day? If so, then you should consider purchasing the eyeglasses that are used to prevent blue light. That way you can always be in control over the amount of blue light you are exposing yourself to, no matter what you are looking at.
On the other hand, if you tend to be distracted by wearing eyeglasses or you tend to lose eyeglasses because you have to constantly take them on and off, you might be better off selecting a blue light filter that can go directly onto your smartphone or computer screen.
