Why You Feel Fatigued After Long Screen Time

In today’s digital world, it’s common to spend hours each day in front of computers, phones, and tablets. While these devices keep us connected and productive, they can also leave you feeling physically and mentally drained. If you’ve ever experienced tired eyes, headaches, or general fatigue after prolonged screen use, you’re not alone. Understanding how screen time impacts your eyes can help you take steps to protect your vision, improve comfort, and maintain long-term eye health.
 

The Link Between Screen Time and Eye Strain

Every time you look at a digital screen, your eyes must constantly refocus and adjust to varying distances, brightness, and contrast levels. Unlike printed material, screens emit light and often display text with less contrast, making it harder for your eyes to maintain sharp focus. Over time, this leads to eye strain, blurred vision, dryness, and headaches.

Your blink rate also decreases by nearly 60% when using a digital device, which can cause dryness and discomfort. These subtle but cumulative effects often result in what many describe as “eye fatigue” after a long workday.
 

Understanding Computer Vision Syndrome (CVS)

Computer vision syndrome, also called digital eye strain, refers to a group of vision-related problems that stem from prolonged screen use. Common symptoms include:

• Eyestrain or discomfort

• Blurred or double vision

• Headaches

• Neck and shoulder pain

• Difficulty refocusing after looking away

While anyone can develop CVS, individuals who already wear glasses or contact lenses - or have uncorrected vision issues - are more likely to experience severe symptoms.
 

The Role of Binocular Vision Dysfunction (BVD)

In some cases, fatigue after screen use may be related to binocular vision dysfunction (BVD). This occurs when your eyes struggle to work together as a team. Even a small misalignment can cause your brain to work overtime to merge two images into one clear picture. The result is eyestrain, dizziness, headaches, and fatigue, especially after extended screen use. Our Cave Creek optometrist can detect subtle eye misalignments and recommend solutions such as specialized lenses or vision therapy to relieve symptoms and restore comfort.
