To alleviate eye fatigue from prolonged computer use, it's essential to adopt a multi-faceted approach that addresses both immediate relief and long-term prevention strategies. Given your experience of discomfort after 15 to 20 minutes of screen time, along with your history of eye allergies and the entoptic phenomenon, here are several recommendations that may help improve your situation.


Immediate Relief Strategies
1. Follow the 20-20-20 Rule: This is a widely recommended practice to reduce eye strain. Every 20 minutes, take a 20-second break to look at something 20 feet away. This helps relax the eye muscles that are strained from focusing on the screen.

2. Blink Regularly: When staring at screens, people tend to blink less, leading to dry eyes. Make a conscious effort to blink more often to keep your eyes moist. You can also try the "blinking exercise," where you close your eyes for a few seconds and then open them wide.

3. Adjust Screen Settings: Since you mentioned needing to dim the brightness, ensure that your screen brightness is comfortable and matches the ambient light in your workspace. Consider using blue light filters or glasses designed to reduce blue light exposure, which can contribute to eye strain.

4. Use Artificial Tears: If you experience dryness, over-the-counter artificial tears can help lubricate your eyes. Look for preservative-free options for more frequent use.

5. Warm Compresses: Applying a warm compress over your closed eyes can help relieve dryness and fatigue. This can be particularly soothing if you feel your eyes are tired or strained.


Long-Term Prevention Strategies
1. Ergonomic Workspace Setup: Ensure your computer screen is at eye level and about an arm's length away. Your chair should support your back, and your feet should rest flat on the floor. Proper posture can significantly reduce strain on your eyes and neck.

2. Regular Eye Exams: Continue to have regular check-ups with your eye care professional. If your symptoms persist, consider asking about specific tests for dry eye syndrome or other conditions that may not have been previously assessed.

3. Limit Screen Time: If possible, try to limit your screen time or take longer breaks. Engage in activities that do not require screen use, such as reading a physical book or going for a walk.

4. Eye Exercises: Incorporate eye exercises into your routine. Simple exercises like rolling your eyes or focusing on near and far objects can help strengthen your eye muscles and improve flexibility.

5. Diet and Hydration: Maintain a diet rich in omega-3 fatty acids (found in fish), leafy greens, and fruits high in vitamins A, C, and E. Staying hydrated is also crucial for maintaining eye moisture.

6. Consider Supplements: While lutein and zeaxanthin are often recommended for eye health, consult with your healthcare provider before starting any supplements, especially if you have specific eye conditions.


Addressing Light Sensitivity
Your observation about needing to adjust the brightness and your discomfort with bright backgrounds may indicate light sensitivity (photophobia). This can be exacerbated by prolonged screen exposure. If you find that darker themes or lower brightness settings help, continue to use them. Additionally, wearing sunglasses with UV protection when outdoors can help reduce overall light sensitivity.


Conclusion
Eye fatigue from prolonged computer use is a common issue, but with the right strategies, you can significantly alleviate discomfort. Implementing the 20-20-20 rule, adjusting your workspace, and maintaining a healthy lifestyle can all contribute to better eye health. If symptoms persist, further evaluation by an eye care professional is essential to rule out any underlying conditions. Remember, taking proactive steps now can help preserve your vision and comfort in the long run.
