You must have had such nights where you were casually scrolling through your social media feed and then ended up spending the entire night on your phone. But, guess what? The blue light emitted by your phone screen is most likely the cause of your inability to sleep. So, you may wonder how it affects your sleep cycle and are anti-blue light screen protectors any good?

The wavelength of blue light is short. Short-wavelength colors can strain your eyes and hinder your sleep if you are constantly exposed to them. This is where anti-blue screen protector comes in handy. It can help minimize the amount of blue light emitted by digital screens.

In this article, I will talk about how blue light affects you and your sleep. It is hard to stay away from digital screens these days. Using anti-blue light screen protectors is the best way to protect your eyes. So, I will also tell you why you should use screen protectors from Ocushield.  

What Is Blue Light?

The sunlight we see seems white. But it actually has seven colors which are violet, blue, indigo, green, yellow, orange, and red. Each of these colors has wavelengths and energy. Blue light is one of the colors that have a shorter wavelength that affects our eyes. Check out Healthline’s article for more information.

The longer the wavelength of color is, the less it affects the eyes. So, colors like red and green are less stressful to the eye. Their wavelength is above 550 nanometers. On the other hand, colors like blue and violet have shorter wavelengths. The wavelength of blue lights is between 435 and 500 nanometers. 

In this modern age, we are not just limited to natural blue light. Devices like laptops, computers, smartphones, tablets, LED lights, fluorescent lights, and other digital devices release blue light all the time. 

How Does Blue Light Affect Your Eyes?

All colors affect the eyes, but the colors of short wavelengths are not always good for the eyes. For example, the violet of the sunray known as the UV ray is harmful to our eyes. Similarly, blue light has a short wavelength that can also harm the eyes. 

The retina of the eye is light sensitive, so UV rays and blue lights can cause serious problems. The cornea and the lens behind it can block UV rays from reaching the retina. Unfortunately, they are not very effective in blocking all virtually produced blue lights. 

According to experts, these are some of the eye problems it can cause:

Macular Degeneration

The macular is the part of the retina that helps to see things clearly. With age, the macular degenerates, and our vision becomes blurry. But blue lights can damage the macular faster than expected. Looking at digital screens can result in dry macular. 

Digital Eye Stress

Digital eye stress has become a common problem among people who use mobiles and laptops for long hours a day. When we use these devices, we end up blinking less than normal. Hence, the eyes get strained. Blue light also partially causes stress on your eyes and the optic nerves. The most common symptoms of eye stress are:

  •       Tired eyes
  •       Dry eyes
  •       Itchiness in eyes
  •       Headaches 
  •       Vision problem

How Does Blue Light Affect Sleep?

The sunlight has a lot of blue lights, which is good for our body. The blue light of day time helps us to sleep at night. But, nowadays, we are exposed to more blue light from our digital devices like phones, tablets, and laptops. The continuous contact with blue light causes sleep deprivation.

Blue light suppresses melatonin. Melatonin is a hormone that is released in our brains. It helps us to fall asleep at night. When you expose yourself to a lot of blue light before bedtime, it gives the wrong signal to the brain. The brain thinks it is daytime since blue light naturally comes from daylight.

Many people use their smartphones until late at night. This exposure causes less secretion of melatonin. As a result, people cannot sleep in time, and the circadian rhythm gets affected. This causes some more health issues, like heart disease, mental stress, and infection.  

Living without modern devices is almost impossible these days. Unfortunately, most of these devices emit blue light. As we can’t seem to keep our hands off our phones or laptops, it’s best to limit our exposure. One way to reduce blue light exposure is by using blue-light-blocking glasses or anti-blue light screen protectors on phones and laptops.

For guaranteed protection from blue light, we recommend you to use anti-blue light screen protectors and glasses from Ocusheild.
