Can you get a headache from being on the computer too long?

Yes.

Eye strain, headaches, blurry vision, and difficulty sleeping are all common symptoms of computer vision syndrome (CVS). This is a condition that affects people who spend a lot of time using computers, smartphones, or other electronic devices. CVS is caused by the way that we use our eyes when we look at a computer screen. When we focus on a computer screen, our eyes are constantly moving in small, rapid movements called saccades. These saccades help us to scan the screen and to read text. However, when we stare at a computer screen for too long, these saccades become less frequent, and our eyes start to dry out. This can lead to eye strain, headaches, and other symptoms.

There are a number of things that you can do to reduce your risk of CVS:

- Blink regularly.

- Take breaks from looking at your computer screen every 20 minutes.

- Use a humidifier to add moisture to the air.

- Use artificial tears to keep your eyes moist.

- Adjust the brightness and contrast of your computer screen.

- Use a standing desk or a sit-stand desk so that you can change your position throughout the day.

If you experience any of the symptoms of CVS, it is important to see an eye doctor. Your eye doctor can diagnose the condition and recommend appropriate treatment.
