The short answer is anti blue light screen protectors were made to protect your eyes and your device. If you own a mobile device, installing a screen protector is one of the first things you should do as it only helps to increase the longevity of your device. I mean why not? You probably spent upwards of $500 on a mobile device and protecting something of value should be second nature. It’s a low cost (considering the price of your gadget) and hassle-free way to help ensure that your device stays as pristine as the day you bought it.
Now ask yourself: how much time do you spend in front of a screen? We live in a digital world where screen time dominates our waking time. The average American is spending more than 10 hours a day in front of a screen, including TVs, PC monitors, and mobile devices. LED technology has made our screens more energy efficient, but they have also increased our exposure to blue light. Prolonged exposure to blue light radiation can cause significant long and short-term damage to your health.
Would you rather protect your phone or your health? The answer to that need not be so polarizing any more. Installing an anti blue light screen protector on your most used devices does both.
What Is Blue Light?
Blue light is everywhere. From taking a walk in a park to flipping a wall switch or turning on your laptop or your phone, you are already being exposed to blue light.
Our sun puts out both visible and invisible radiation. The visible part is light while infrared and ultraviolet are the invisible ones. We all know that UV rays are detrimental to our health. They can cause sunburn and even cancer. It has something to do with their wavelengths and the energy they possess. To simplify the science, the shorter the wavelength, the higher the energy it puts out.
Now you may be thinking, if it’s in nature itself, then blue light shouldn't be bad. Well, blue light isn’t all bad. What we want to focus on here is how LED technology uses visible light and how long we are exposed to it. To reduce costs, LED screens use cool white light as the base to project images. This is different from how natural light is composed.
The amount of blue light in LED screens is significantly higher than that from natural sunlight. This is the same for LED lighting and fluorescent bulbs.
How Does Blue Light Affect Us?
As mentioned before, exposure to blue light isn’t all bad. In fact, we need this in our daily lives. Our eyes are not good at blocking blue light. While the anterior structures of our eyes block UV rays from reaching our retina, almost all blue light passes through the cornea and lens. What time of the day we are exposed to it, how intense it is, and for how long we are exposed to it affect us in different ways.
Let’s look at some benefits and harmful effects of blue light.
Blue light is good for:
- Regulating our circadian rhythm. Blue light is important in maintaining and regulating our natural sleep and waking patterns.
- Boosting our alertness, and helping memory and cognitive functions. Blue light stimulates the brain more than any other light. With moderate exposure, studies have shown that it increases memory and brain response.
- Elevating moods. It is also used in therapy to treat seasonal affective disorder - a type of depression related to change in seasons.
Too much blue light is harmful because it:
- Disrupts our circadian rhythm. Exposure to blue light at night suppresses the secretion of melatonin 2 times more than any other light. It tricks our brain into thinking that it’s still daytime. This potentially leads to insomnia and daytime fatigue. Moreover, lack of sleep increases our risk of depression, diabetes and cardiovascular problems.
- Causes digital eye strain syndrome. Blue light has a high energy value and is susceptible to flickering and glare. Overexposure to blue light can cause eye strain; blurry vision; and head, neck, and back pains.
- May cause permanent eye damage. Because blue light penetrates all the way to the retina, it can cause damage to these light-sensitive cells. There is growing concern in the long-term effects of exposure to blue light in increasing the chance of macular degeneration.
How Can I Protect Myself From Blue Light?
There are many options available to protect yourself from blue light. Our devices have night more, night shift, or night light which are all digital blue light filters. How these work is they alter the light projected by the LEDs. This results in an overall orange screen and may not be as visually appealing when using your device.
Another way is through the use of blue light filter glasses. These glasses have a clear physical filter that absorbs the transmission of blue light without sacrificing color. They are available without a prescription. If you do have prescription glasses, then you will have to have the lenses replaced with a blue light coated one which can be more costly. Also, if you don’t like wearing glasses, then this option isn’t for you.
The Anti Blue Light Screen Protector
This screen protector offers protection for your eyes and your device. Anti blue light screen protectors are made with tempered glass which has a 9H hardness rating. It protects your device’s screen from scratches as well as impact. With a thickness of about 0.33mm, it makes for seamless operation of your device without losing any responsiveness. These screen protectors also have an oleophobic coating that resists fingerprint marks and smudges, making them easy to clean and maintain. They are widely available for just about any model of device and are precision cut, making for a perfect fit with total screen coverage. They also have a clear anti blue light coating sandwiched in the material. It blocks blue light radiation while maintaining your screen’s clarity, color contrast and vibrancy. They’re relatively easy to install and once you do, you can enjoy your view worry free. No need to recall where you misplaced them. And if you break them, they’re easily replaceable. It’s really the most effective way to ensure you and your loved one’s eyes are protected.
