Hello! Thank you for your detailed inquiry regarding your eye health concerns, particularly related to eye fatigue and floaters. It's understandable to feel anxious about your symptoms, especially given your history of myopia and floaters. Let's break down your concerns and explore the potential causes and solutions.

Firstly, it's important to recognize that eye fatigue, also known as asthenopia, is a common issue, especially among individuals who spend extended periods in front of screens. Symptoms of eye fatigue can include discomfort, dryness, blurred vision, and even headaches. The fact that you are experiencing increased fatigue after long hours of computer use is not unusual. The phenomenon of "computer vision syndrome" is well-documented and can lead to various visual disturbances.

Regarding the specific symptoms you've described:
1. Flashes of Light: The white flashes you see in your left eye, especially when lying down, could be related to the vitreous gel in your eye pulling away from the retina, which is common in individuals with myopia. This is often benign, but it's crucial to monitor these symptoms, as they can sometimes indicate more serious conditions, such as retinal tears or detachments.

2. Floaters: The floaters you experience, particularly when looking at bright lights or screens, are also common, especially in those with a history of myopia. Floaters are tiny clumps of gel or cells inside the vitreous that cast shadows on the retina, which you perceive as spots or strands. While they can be annoying, they are usually harmless unless accompanied by sudden changes in vision or an increase in the number of floaters.

3. Eye Fatigue: Your observation that your eyes become fatigued after about 15 minutes of computer use aligns with common experiences among those who engage in prolonged screen time. This can be exacerbated by poor lighting, screen glare, or improper viewing distances.

Regarding your concerns about the necessity of dilation during your eye exams, it's worth noting that while dilation can provide a more comprehensive view of the retina and help detect issues that might not be visible otherwise, many modern diagnostic tools can offer significant insights without the need for dilation. If your eye doctor has performed thorough examinations using advanced equipment and found no issues, it may not be necessary to undergo dilation unless new symptoms arise or if they suspect a condition that requires closer inspection.

However, if you continue to experience discomfort or if your symptoms worsen, it would be prudent to seek a follow-up appointment. You might also consider discussing your symptoms in detail with your eye care provider to ensure that all your concerns are addressed.

In the meantime, here are some strategies to help alleviate eye fatigue:
- Follow the 20-20-20 Rule: Every 20 minutes, take a 20-second break to look at something 20 feet away. This helps relax the eye muscles.

- Adjust Your Workspace: Ensure that your computer screen is at eye level and about an arm's length away. Proper lighting can also reduce glare and strain.

- Stay Hydrated: Drink plenty of water and consider using artificial tears to combat dryness.

- Limit Screen Time: If possible, take regular breaks from screens to give your eyes a chance to rest.

- Consider Blue Light Filters: Using blue light blocking glasses or screen filters can help reduce eye strain from prolonged screen exposure.

In conclusion, while your symptoms may be concerning, they are not uncommon for someone with your background and current lifestyle. Regular check-ups with your eye care provider are essential, especially if you notice any changes in your vision. If your symptoms persist or worsen, don't hesitate to seek further evaluation. Your eye health is paramount, and staying proactive is the best approach. Thank you for reaching out, and I hope this information helps clarify your concerns!
