Seeing flashes of light?

Hello, doctor.
About six months ago, I noticed that I have floaters in both eyes.
My prescription is -4.50 in the left eye with -2.25 astigmatism, and -4.50 in the right eye with -0.75 astigmatism.
The floaters appear as transparent dots, black spots (sometimes they appear bright), transparent worm-like shapes, and clumps of transparent material.
Since developing floaters, I have been very anxious, fearing that something is wrong with my eyes.
The doctor I consulted did not specifically explain whether my floaters are benign; he only mentioned that individuals with high myopia should have their retinas checked approximately once a year, or return for an examination if there is a significant increase in floaters.
Recently, over the past 5 to 6 days, I have noticed that when I look at a wall or paper, if I cover my right eye and only use my left eye, I see little flashes of light on the wall after opening my left eye.
Additionally, when I look down from above or from left to right, I see flashes of light that follow my gaze, which disappear in about a second; my right eye does not have this issue.
Yesterday morning, due to my concern about whether the floaters were worsening, I went to see a doctor near my school.
The doctor examined my retina and found no issues.
He mentioned that if there were retinal tears, I would likely see a streak of light and advised me to return promptly if I notice an increase in floaters but the flashes disappear.
Although I have seen a doctor, I still have some concerns and would like to ask a few questions:
1.
I seem to recall experiencing similar flashes in the past, and when I consulted a doctor then, I was told I was overly sensitive.
I later relaxed and stopped paying attention to it, but I have noticed this situation again recently.
Am I being overly sensitive regarding my current situation?
2.
I have dry eye syndrome; could the above situation be related to my dry eyes?
3.
If there are issues such as retinal tears or detachment, would I definitely notice them? What symptoms should I look out for? Since developing floaters, I often worry about this issue and fear that I might not notice any problems.

4.
If I later find that the flashes have disappeared but the floaters have not increased, do I still need to get checked?
Thank you for your answers.

Hello, Student Chen:
1.
You may be overthinking it; if the examination shows no issues, there's no need to worry too much.
2.
It should be fine.
3.
You may experience visual field defects, more severe floaters, or even blurred vision; generally, you should be able to feel these symptoms.
When performing a self-check, please cover one eye while examining the other to avoid affecting your observation.
4.
If the flashes have stopped but the floaters have not increased, there is even less reason to be anxious.
However, it is still recommended that you have regular check-ups.
Taiwan E-Hospital Puzi Hospital Ophthalmology: Monday to Friday, 8:00 AM to 12:00 PM; Wednesday afternoon, 1:00 PM to 4:30 PM.
Online responses should only be used as a reference; if necessary, you should seek medical attention at a healthcare facility.
I hope to have the opportunity to serve you.

More Info

When it comes to eye health, particularly regarding symptoms like floaters and flashes, it's understandable to feel anxious, especially if you have a history of eye issues. Let's break down your concerns based on the information you've provided.

1. Sensitivity to Symptoms: It's not uncommon for individuals with a history of eye problems, such as floaters, to become more attuned to changes in their vision. The flashes you're experiencing, especially after covering one eye, could be related to the way your brain processes visual information when there's a change in light or focus. Your doctor’s assessment that you might be overly sensitive is a valid point. Many people with similar conditions often report heightened awareness of their symptoms, which can lead to increased anxiety.

2. Dry Eye Syndrome: Dry eyes can indeed contribute to visual disturbances. If your eyes are not adequately lubricated, it can lead to sensations of discomfort, which might be interpreted as flashes or other visual anomalies. However, while dry eyes can cause discomfort and visual disturbances, they are less likely to cause the specific flashes you describe, which are more commonly associated with vitreous changes or retinal issues.

3. Retinal Concerns: If there were a retinal tear or detachment, symptoms typically include sudden flashes of light, a significant increase in floaters, or a shadow or curtain effect over your vision. However, not everyone experiences these symptoms in the same way. Some individuals may not notice a tear until it has progressed significantly. Regular check-ups, especially given your high myopia, are crucial. Your doctor’s advice to monitor for an increase in floaters or changes in your vision is sound. If you notice any significant changes, such as a sudden increase in floaters or a change in the quality of your vision, you should seek immediate medical attention.

4. Follow-Up After Changes: If you notice that the flashes have stopped but your floaters remain stable, it may not be necessary to return for an immediate check-up, especially if your previous examinations have shown no issues. However, if you experience any new symptoms or if your floaters increase significantly, it would be prudent to consult your eye care professional again.

In summary, while it’s natural to feel anxious about your eye health, especially with a history of floaters and myopia, it’s important to rely on the assessments of your eye care professionals. They have the tools and expertise to monitor your condition effectively. Regular eye exams are essential, particularly for individuals with high myopia, as they can help catch any potential issues early.
To maintain your eye health, consider the following tips:
- Stay Hydrated: Proper hydration can help with dry eyes.

- Use Artificial Tears: If you have dry eye symptoms, using preservative-free artificial tears can provide relief.

- Limit Screen Time: Take regular breaks when using screens to reduce eye strain.

- Protect Your Eyes: Wear sunglasses to protect against UV light and reduce glare.

- Healthy Diet: A diet rich in omega-3 fatty acids, leafy greens, and colorful fruits and vegetables can support eye health.

Lastly, if your anxiety about your eye health continues to affect your quality of life, consider discussing this with your healthcare provider. They may suggest strategies to help manage your anxiety regarding your symptoms. Remember, being proactive about your eye health is key, and you’re doing the right thing by seeking information and clarification.
