Eye Symptoms: A Programmer's Guide to Eye Health

Hello, doctor. Regarding various eye symptoms?

Hello Doctor, I have been working in computer programming for nearly 10 years.
After work, I often play mobile games with friends for long periods, sometimes even over 7 hours in a single day during holidays.
I used to have no issues looking at the screen for 8 hours, but in recent years, I’ve noticed that after 2-3 hours, my vision starts to become blurry, and I need to squint slightly to see clearly.
If I open my eyes fully, not only do I feel the blurriness, but everything also seems overly bright.
Could you explain why this is happening?
In the past two years, I have noticed I have floaters.
Last week, after playing on my phone for 7-8 hours continuously, on Saturday the 22nd, I observed the following: 1.
I could see floaters even with my eyes closed in bright areas.
2.
When my eyes were closed, I saw a yellowish cross-like shape, while most of the other floaters were black.
3.
When I woke up this morning and was lying in bed, I covered my eyes with a blanket and still saw a cyan point in the center that gradually shrank until it disappeared.
After repeating this action 4-5 times, it was gone.
4.
I feel like my line of sight is partially blocked by my eyelids, yet I can still see objects.
5.
Sometimes, I perceive things as if they are in a colored pixelated pattern.
6.
Occasionally, when I look at something, I experience a flash sensation, similar to when you stand up quickly after squatting for a long time.
If I focus on an object for too long, I also feel a similar flash sensation, and sometimes my vision seems to dim gradually, but it appears normal again after I open and close my eyes.
7.
Since last Saturday, even with reduced use of electronic devices, I still feel a sense of heaviness and swelling in my eyes and the back of my head.
8.
When I cover one eye to look at the computer, I notice that the right eye sees things as softer and darker compared to the left eye.
I apologize for listing so many issues.
Based on what I’ve described, what symptoms do you think I might have? I’m unsure how to explain my situation to a doctor at the hospital, as some doctors seem eager to conclude the appointment quickly, which makes me nervous and unsure of what to say.
I truly appreciate you taking the time to read my concerns and provide answers.
Thank you!

More Info

Hello! It sounds like you are experiencing a range of concerning eye symptoms, particularly related to your extensive use of screens due to your programming work and gaming habits. Let's break down your symptoms and discuss potential causes and solutions.

Understanding Your Symptoms
1. Blurred Vision and Sensitivity to Light: The fact that you need to squint to see clearly after a few hours of screen time suggests that your eyes are becoming fatigued. This is common among individuals who spend long hours in front of screens, often referred to as Computer Vision Syndrome (CVS). Symptoms of CVS include blurred vision, dry eyes, and light sensitivity, which can all contribute to discomfort.

2. Floaters and Visual Disturbances: The appearance of floaters (the "flying spots" you see) is generally benign, especially if they have been present for a while. However, the sudden onset of new floaters or changes in your vision, such as seeing flashes of light or a "grid" pattern, can be concerning. These symptoms may indicate changes in the vitreous gel of the eye or even retinal issues, which require immediate attention from an eye care professional.

3. Pressure and Pain: The sensation of pressure or swelling in the eyes, along with headaches, can be attributed to prolonged screen time and poor ergonomics. It’s essential to take regular breaks and ensure that your workstation is set up correctly to minimize strain.

Recommendations for Eye Health
1. Follow the 20-20-20 Rule: Every 20 minutes, take a 20-second break to look at something 20 feet away. This helps reduce eye strain and fatigue.

2. Adjust Your Environment: Ensure that your workspace is well-lit to reduce glare on your screen. Position your monitor at eye level and about an arm's length away to minimize strain.

3. Stay Hydrated and Blink Regularly: When focused on screens, people tend to blink less, leading to dry eyes. Make a conscious effort to blink more often and consider using artificial tears if dryness persists.

4. Limit Screen Time: Try to reduce the amount of time spent on screens, especially during your off-hours. Engage in activities that do not involve screens to give your eyes a break.

5. Regular Eye Exams: Given your symptoms, it’s crucial to schedule an eye exam with an optometrist or ophthalmologist. Be sure to mention all your symptoms, including the floaters, light sensitivity, and any visual disturbances. This will help the doctor understand your situation better and provide appropriate care.

Communicating with Your Doctor
When you visit your doctor, it’s important to be clear and concise about your symptoms. Here’s a suggested approach:
- Start with a Brief Overview: "I've been experiencing blurred vision, light sensitivity, and floaters, especially after long hours of screen use."
- List Specific Symptoms: Mention each symptom you’ve experienced, such as the flashes of light, the sensation of pressure, and any changes in your vision.

- Discuss Your Work Habits: Explain your daily screen time and any recent changes in your routine that may have contributed to your symptoms.

- Express Your Concerns: Let the doctor know that you are worried about potential underlying issues, especially with the new visual disturbances.

Conclusion
Your symptoms are concerning, especially given your extensive screen time and the recent changes in your vision. It’s essential to take these symptoms seriously and seek professional help. By following the recommendations above and communicating effectively with your healthcare provider, you can work towards improving your eye health and alleviating your symptoms. Remember, early intervention is key to preventing potential complications. Take care!
