Why Do My Eyes Hurt When Using My Computer But Not My Phone or TV?

Have you ever experienced eye pain or discomfort when using your computer, but not when you use your phone or television? There could be several reasons for this phenomenon, ranging from simple viewing habits to more serious optical issues.

Understanding Common Causes

One of the common reasons for eye discomfort when using a computer is Computer Vision Syndrome (CVS), also known as Digital Eye Strain. This syndrome can cause a range of symptoms such as eye fatigue, dryness, and actual pain. These symptoms can be exacerbated by factors such as prolonged use and staring at screens without enough breaks. Another possible reason is a refractive error that may not be corrected with your current glasses or contact lenses, especially if you have a prescription for intermediate distance.

Impact of Screen Quality and Viewing Distance

Recent experience has also shown that the quality of the screen itself can significantly affect eye health. Cheap and typically low-quality panels can emit excessive radiation, leading to a tingling sensation in the eyes. This is particularly noticeable with two monitors I used, which were brand-name but cheap. Contrary to popular belief, dry eyes are not the primary cause of eye strain in this context. For instance, my office laptop and high-quality phone did not cause these issues, suggesting that it's more about the quality of the display than the content viewed.

Blue Light Exposure and Solution

Studies have shown that blue light, which has a shorter wavelength and penetrates deeper into the eyes, can cause retina damage over time. Blue light from computer screens can lead to increased eye strain and discomfort, particularly for those who spend long hours staring at their monitors. It is important to note that computer screens generally emit more blue light than mobile phones or televisions, making them a more significant contributor to eye strain.

To mitigate the effects of blue light, a company in India has developed Advanced Light Control Screens (ALCS). These screens are designed to block harmful blue light while providing a smoother viewing experience with protective features. While these screens may be expensive on platforms like Amazon, they can be found at a more affordable price on their official website, This cost-effective solution is particularly useful for those who spend extensive time in front of their computer screens.

Adjusting Screen Brightness for Comfort

Another simple adjustment you can make to reduce eye strain is to adjust your screen brightness according to your surroundings. Studies show that large differences in brightness can cause eye strain. For example, if you are in a bright environment, your screen should have a higher brightness setting, whereas in a darker room, it should have a lower setting.

Changing the brightness can be confusing for many people, especially those who are less tech-savvy. Here’s a guide on how to adjust your brightness settings:

On Windows laptops and Macs, look for a key that resembles a sun or brightness the FN key along with the brightness key can also help.

While tech-savvy individuals may already know how to adjust these settings, for others, it's a good idea to bookmark or save this guide for future reference.

Conclusion

Eye strain and discomfort when using a computer can be addressed through a combination of screen quality, viewing habits, and simple adjustments like brightness settings. By choosing high-quality screens and making necessary adjustments, you can significantly reduce the risk of eye strain and associated discomfort.
