Eye Flashes: Causes and Solutions for Myopia Patients - Ophthalmology

More Info

---

Your symptoms of experiencing flashes of light and seeing small black spots, especially in bright environments, can be concerning, especially given your history of myopia and recent laser treatment. Let's break down the potential causes and solutions for your situation.


Possible Causes
1. Vitreous Detachment: With myopia, especially at higher degrees like yours, the vitreous gel inside the eye can become more prone to detachment from the retina. This can lead to symptoms such as floaters (the black spots you see) and flashes of light. These flashes occur when the vitreous pulls on the retina, creating a sensation of light.

2. Retinal Issues: Although less common, flashes and floaters can also indicate more serious conditions like retinal tears or detachments. Given your history of laser treatment, it’s essential to monitor any new symptoms closely.

3. Eye Fatigue: Prolonged screen time or reading can lead to eye strain, which may cause temporary visual disturbances, including flashes or spots. This is often referred to as digital eye strain or computer vision syndrome. Symptoms can include dryness, discomfort, and visual disturbances.

4. Migraine Auras: Even if you do not have a history of migraines, some individuals experience visual disturbances known as auras, which can include flashes of light. These can occur independently of a headache.

5. Dry Eyes: If your eyes are not adequately lubricated, you may experience visual disturbances. This can be exacerbated by prolonged screen time, leading to a sensation of flashes or spots.


Recommendations
1. Eye Examination: It’s crucial to have a comprehensive eye examination, especially since you have a history of myopia and recent laser treatment. An eye care professional can perform a dilated fundus exam to check for any retinal issues.

2. Monitor Symptoms: Keep a log of when these symptoms occur, their duration, and any associated activities (like screen time or reading). This information can be helpful for your eye care provider.

3. Rest Your Eyes: Implement the 20-20-20 rule: every 20 minutes, take a 20-second break to look at something 20 feet away. This can help reduce eye strain.

4. Proper Lighting: Ensure that your workspace is well-lit to reduce glare and strain on your eyes. Avoid working in dim lighting, especially when using screens.

5. Stay Hydrated: Drink plenty of water and consider using artificial tears if you experience dryness. This can help maintain eye moisture and comfort.

6. Limit Screen Time: If possible, reduce the amount of time spent on screens, especially if you notice that symptoms worsen after prolonged use.

7. Follow-Up: If your symptoms persist or worsen, or if you experience new symptoms such as a sudden increase in floaters, flashes, or changes in vision, seek immediate medical attention.


Conclusion
While your symptoms may be related to eye fatigue or vitreous changes, it is essential to rule out any serious conditions, especially given your myopia and previous laser treatment. Regular eye exams and being mindful of your visual habits can significantly contribute to maintaining your eye health. If you have any further concerns or if your symptoms change, do not hesitate to consult with your eye care provider.
