Does LCD Phone Screen Hurt Your Eyes?

With the increasing usage of smartphones in our daily lives, the amount of time we spend staring at a screen has also increased. This has led to concerns about the effects of mobile phone LCD phone screens on our eyes. In this article, we will discuss the impact of LCD phone screens on our vision and whether it's true that they can harm our eyes.

What is an LCD Phone Screen?

An LCD ( Display) Phone Screen is a display screen made of two glass plates with liquid crystals in between them. When an electrical charge is applied to the crystals, they change their position and allow the color to show through. Most modern smartphones use LCD screens.

Do LCD Phone Screens Emit Harmful Blue Light?

One of the most significant concerns about LCD phone screens is the amount of blue light they emit. Blue light is a type of high-energy visible light that can cause damage to the retinas in our eyes. However, the amount of blue light emitted by an LCD phone screen is not harmful enough to cause permanent damage to our eyes. People who are exposed to blue light at night might have disrupted sleep patterns, but this is not an issue for daytime exposure to blue light.

How Does Staring at an mobile phone LCD Screen Affect Your Eyes?

While LCD screens do not emit harmful blue light, they do emit bright light that can cause eye strain and fatigue. These symptoms occur because staring at the screen for extended periods causes our eyes to work harder to focus. When we stare at a screen, our eyes do not blink as often as they usually do, which can cause dryness and irritation. People who spend a lot of time in front of screens might also experience headaches.

How to Reduce Eye Strain When Using LCD Screens?

Fortunately, there are many ways to reduce eye strain from LCD screens. Firstly, make sure that your screen is at the right angle and distance from your eyes. The screen should be about arm's length away, and the top of the screen should be at or slightly below eye level. Secondly, adjust the brightness of the screen so that it's comfortable for your eyes. It should be neither too bright nor too dim. Thirdly, take breaks often. Every 20 minutes, look away from the screen and focus on an object in the distance for 20 seconds. Also, try to blink more often to prevent dry eyes. Lastly, consider using blue light filters. Many phones have a blue light filter inbuilt or you can download an app that reduces the amount of blue light emitted by your phone screen.

Conclusion

While LCD phone screens do not emit harmful levels of blue light, staring at the screen for extended periods can cause eye strain and other symptoms. Fortunately, there are many ways to reduce these symptoms and make your experience with your phone more comfortable. Remember to adjust your screen’s angle and brightness, take breaks often, blink more often and use blue light filters. By following these simple tips, you can protect your eyes while using your smartphone.
