Hello! Thank you for sharing your concerns regarding the visual disturbances you're experiencing, particularly the flashing lights and the perception of movement on white surfaces. Based on the symptoms you've described, it’s understandable that you feel anxious, especially since these disturbances can significantly affect your daily life.

The phenomenon of seeing flashes of light or experiencing visual disturbances, such as the perception of movement or halos around lights, can be attributed to several potential causes. Here are some common explanations:
1. Vitreous Detachment: As we age, the vitreous gel inside the eye can begin to shrink and pull away from the retina. This process can lead to flashes of light, especially in peripheral vision. If the vitreous pulls too hard, it can sometimes cause retinal tears, which is a more serious condition.

2. Migraine Aura: Some individuals experience visual disturbances as part of a migraine aura, even without a headache. These can include flashing lights, zigzag patterns, or temporary blind spots. The symptoms can last from a few minutes to an hour.

3. Retinal Issues: Although your eye pressure is normal, it’s still essential to rule out any retinal problems. Conditions such as retinal tears or detachments can cause similar symptoms, and these require immediate medical attention.

4. Ocular Migraines: These are characterized by temporary visual disturbances, including flashes of light or blind spots, which can occur without a headache. They are generally harmless but can be alarming.

5. Dry Eyes: As your doctor mentioned, dry eyes can lead to visual disturbances. When the eyes are not adequately lubricated, it can cause blurriness or a sensation of something moving in your vision.

6. Visual Snow Syndrome: This is a rare condition where individuals see visual "snow" or static, which can be accompanied by other visual disturbances, including light sensitivity and afterimages.

7. Psychological Factors: Stress and anxiety can also manifest as visual disturbances. If you are under significant stress, it might be worth exploring relaxation techniques or speaking with a mental health professional.

Given that your symptoms have persisted and have not improved, it is crucial to seek further evaluation from an eye care professional. A comprehensive eye examination, including a dilated fundus exam, can help assess the health of your retina and rule out any serious conditions. If necessary, your doctor may refer you to a specialist, such as a retinal surgeon, for further evaluation.

In the meantime, here are some recommendations to help manage your symptoms:
- Stay Hydrated: Ensure you are drinking enough water, as dehydration can contribute to dry eyes.

- Use Artificial Tears: Over-the-counter lubricating eye drops can help alleviate dryness and discomfort.

- Limit Screen Time: If you spend a lot of time on screens, take regular breaks to reduce eye strain.

- Manage Stress: Engage in relaxation techniques such as deep breathing, meditation, or yoga to help reduce anxiety.

In conclusion, while your symptoms may not indicate a severe issue, it is essential to continue monitoring them and seek further evaluation if they persist or worsen. Your eye health is paramount, and addressing these concerns with a qualified professional will provide you with the best course of action. Please take care, and I hope you find relief from your symptoms soon!
