Hello! Thank you for reaching out with your concerns regarding your eye health. It sounds like you are experiencing a range of visual disturbances, and I appreciate the opportunity to address your questions.

1. Visual Persistence and Blurriness: The phenomenon you describe, where text appears to "run" or blur when looking at your phone or reading, can be indicative of a few potential issues. Visual persistence, or the sensation of seeing an image after it has disappeared, can occur due to various factors, including fatigue, eye strain, or even underlying neurological conditions. Given that you mentioned you have a history of myopia (nearsightedness) and floaters, it’s essential to consider that these visual disturbances might be exacerbated by prolonged screen time or inadequate breaks. If you are experiencing significant visual disturbances, it is advisable to consult an eye care professional for a comprehensive evaluation.

2. Flashing Lights and Afterimages: The flickering sensation you experience upon waking or after resting your eyes can be attributed to several factors. This could be related to the way your eyes adjust to light after being closed or resting. However, if this sensation is accompanied by other symptoms such as headaches or persistent visual disturbances, it may warrant further investigation. Conditions such as migraines can cause visual aura, which may include flickering lights or afterimages. If this is a new symptom or has worsened, it’s crucial to discuss it with your healthcare provider.

3. Visual Acuity and Eye Health: You mentioned that your right eye has a refractive error of only 100 degrees, yet you are experiencing significant blurriness with a visual acuity of 0.2. This discrepancy suggests that there may be more than just refractive error at play. A thin retina can lead to complications, including retinal detachment, which can affect vision. It’s important to follow up with your eye care provider to monitor the health of your retina and to ensure that there are no other underlying issues contributing to your visual symptoms.

4. Impact of Laser Surgery: Laser procedures, such as those used to repair retinal issues, can sometimes lead to temporary or permanent changes in vision. While many patients experience improved vision after such procedures, others may notice changes in clarity or the emergence of new visual symptoms. If you believe your vision has worsened since the laser treatment, it is essential to communicate this to your ophthalmologist. They can assess whether the changes are related to the procedure or if there are other factors at play.

In summary, the symptoms you are experiencing—visual persistence, flickering lights, and significant blurriness—are concerning and should be evaluated by a qualified eye care professional. It’s essential to maintain regular eye exams, especially given your history of myopia and retinal issues. Additionally, practicing good eye hygiene, such as taking regular breaks from screens, ensuring proper lighting while reading, and managing eye strain, can help alleviate some discomfort.

If you have further questions or if your symptoms persist, please do not hesitate to seek medical advice. Your eye health is paramount, and addressing these issues early can lead to better outcomes. Thank you for sharing your concerns, and I wish you the best in your journey toward improved eye health!
