Staring at a computer screen for extended periods of time can cause eye strain and discomfort, but it is unlikely to cause permanent vision loss or blindness.
Prolonged use of computers, smartphones, and other digital devices can lead to a condition called computer vision syndrome (CVS), which causes symptoms such as eye strain, headaches, blurred vision, and dry eyes. These symptoms can be uncomfortable, but they are usually temporary and resolve once you take a break from the screen.
To reduce the risk of CVS, it’s important to follow good visual hygiene practices, such as:
- Taking frequent breaks: Take a break every 20-30 minutes to give your eyes a rest.
- Blinking regularly: Blinking helps to moisten the eyes and reduce dryness.
- Adjusting the screen: Make sure the screen is positioned so that it’s at a comfortable viewing distance and angle, and adjust the brightness and contrast to a level that’s comfortable for you.
- Using artificial tears: If your eyes feel dry, you can use over-the-counter artificial tears to help moisturize them.
- Practicing good posture: Maintain good posture while using the computer to reduce neck and back strain.
By following these tips, you can reduce the risk of eye strain and discomfort from prolonged screen use. However, if you experience persistent eye problems or vision changes, it’s important to talk to an eye doctor for a proper evaluation.
