Do you feel that your head hurts more than usual? Is it difficult for you to fall asleep? Then, chances are that your smartphone might be the problem. Scientists have revealed that blue light omitted by electronic devices such as your smartphone or tablet is contributing to the problem. The good news is that it is possible to block out this blue light in order for you to easily rest. Whether you use an Android device or an iPhone, it produces blue light which is harmful. But, before you find out how you can eliminate blue light, it is crucial that you understand just what blue light exactly is.
What Is Blue Light?
Believe it or not, blue light can be found just about everywhere in today’s digital world. However, it is important that you understand that how your phone screen time affects your eyes. Sunlight consists of blue, green, yellow, orange, and red light rays and different shades of these colors depending on the wavelength and energy of the individual rays. When these are combined, they create sunlight or while light. There is no need to get into the complex physics of it all. However, the wavelength of light rays and their energy have an inverse relationship. Hence, light rays which have a long wavelength tend to contain much less energy and vice-versa.
The red rays have much longer wavelengths and provide less energy. On the other hand, the blue rays have more energy and a shorter wavelength. The infrared rays are the electromagnetic rays that are ahead of the red end in the light spectrum. They are invisible, yet warming. For instance, the warming lamps which you might find at a local eatery ooze infrared radiation. However, they also emit visible red light which allows people to know that it is on. Blue light rays are on the other side of the visible light spectrum. They have the highest energy and the shortest wavelength. Blue light rays are often called violet light or blue-violet light. Hence, invisible electromagnetic rays that are beyond the light spectrum are known as UV (ultraviolet) radiation. Although sunlight is our main source of exposure to blue light, there are many indoor sources which are man-made that also produce blue light such as smartphones, flat-screen televisions, and LED lighting. But, a significant amount of blue light is emitted by smartphones and other electronic devices.
Even though the amount of HEV light that is emitted by these devices is just a fraction of what the sun emits, we tend to spend a lot of time in close proximity to such devices or even using these devices. Thus, eye doctors and many other healthcare professionals around the world are worried about the long-term impact of blue light on health. This has led to the emergence of blue light filters which help conveniently reduce blue light exposure.
What Is A Blue Light Filter?
A blue light filter is used to reduce the blue light exposure of smartphones and other devices. It is used as protective eyewear. Since we tend to spend a lot of our time using electronic devices that expose us to blue light, it is crucial that we take precautions. Blue light from electronic devices is harmful. Many eye care firms are working together for enhancement in technology and are educating the public on possible solutions to this problem. This is why it is a good idea to use a blue light filter such as the PERFECTSIGHT iphone blue light filter to help ensure that you are not fully exposed to blue light.
The more time we spend looking at our electronic devices, the more eye discomfort we will experience. It can also lead to many long-term health problems. Blue light might impact your vision and cause premature aging to your eyes. Digital eye strain is commonly associated with overexposure to blue light. Moreover, macular degeneration is another risk which is associated with too much exposure to blue light. Continuous exposure to the HEV light will over time cause real damage to your retinal cells. Thus, if the retinal cells are damaged, it would cause permanent vision loss. Although there is no defined amount for blue light exposure that causes macular degeneration, the more blue light you are exposed to the more at risk you are. Other symptoms caused by blue light radiation include fatigue, blurred vision, headaches, and sleeping disorders.
What Does a Blue Light Filter Do?
If you want to ensure that you are not overexposed to blue light, it is crucial that you use a blue light filter. The blue light filter works by providing little magnification which reduces eye strain. This helps reduce excess blue light when you use your smartphone, or any other digital device. The blue light filter offers a mild yellow appearance to the lenses. The commonly used blue light filters or lenses have an orange, copper, or brown look.
When you use the blue light filter, you will notice some clarity and magnification immediately. However, to truly observe the benefits of a blue light filter, you need to it for at least two weeks. The blue light filter is easy to use and is beneficial to your health. Once you have used it for some time, you will notice that your eyes are not nearly as tired as they used to be. Moreover, you will be better able to see things from a distance. You might be considering using glasses which have a blue light filter, but there is no need to do so because the blue light filter for electronic devices such as your smartphone is an improvement. Since blue light has shorter wavelengths, you do not notice its side effects until they truly kick in. Digital eye strain and blue light fatigue has become extremely common and the best way to counter it is by using blue light filter as it helps block out excessive light.
