That’s why you need a blue light screen protector to filter out the blue light from your phone that is bad for your health. Read on to learn more about why you need one.
How is Blue Light Bad for You?
Blue light is one of the light rays that make up visible light from either the sun or digital screens. In the visible electromagnetic spectrum, blue light has the highest energy and shortest wavelength out of all the other light rays. This is the reason it’s able to penetrate past the cornea of your eye to the retina.
The sun emits blue light which plays a crucial role in your biological functions. It boosts your cognitive functions such as memory, alertness, reaction times, and moods. It also regulates your body clock so that you feel sleepy at certain times and you’re alert at other times. The same, however, cannot be said of artificial blue light from your smartphone.
Blue light from your smartphone is bad for you because you are exposed to it throughout the day and even late into the night. Many people have been caught under the spell of checking their phones every few minutes to see if they have any new notifications even if they didn’t hear anything. It’s the first thing they reach out to once they wake up and the last thing before they sleep. Not to mention, they are held so close to the face that eyes receive the full glare of blue light.
The negative consequences that follow overexposure to blue light from smartphones are:
Eye Conditions
Since the cornea cannot block blue light from entering the eye, it penetrates through and causes eye conditions such as digital eye strain. Digital eye strain is a common problem that affects almost everyone who spends too much time on their phones or other digital gadgets like computers. It causes you to have dry, sore, and red eyes, headaches, and blurry vision. You might also like New Apple iPad Air 4th Generation
Excess blue light exposure can also lead to the development of age-related macular degeneration (AMD). This is a disease where you experience blurry vision because the cells of the retina are damaged. It typically develops later in life but blue light can cause its early onset. Blue light does this by triggering the increased production of free radicals which causes the oxidative damage of cells in the retina.
Poor Sleep
When the sun sets, the absence of blue light triggers the release of melatonin from the brain which makes you feel drowsy. This is why you feel sleepy when it’s dark. In the morning, blue light from the sun penetrates your eye and the release of melatonin is stopped; this wakes you up.
When you use your smartphone at night, you expose your body to blue light which is only meant to happen during the day. As a result, your brain keeps you awake and when you finally put your phone away, your body takes a long time to wind down for you to sleep. You, therefore, end up suffering from insomnia. Even if you in; you will keep being startled awake because your circadian rhythm is all messed up.
Health Issues
You need enough quality sleep for you to be healthy so when you are kept awake by blue light from your phone, things can go very wrong. Some of the conditions you may develop include heart diseases, obesity, depression, diabetes, mood disorders, and certain types of cancer.
