Hello! Thank you for your questions regarding your retinal issues and the symptoms you're experiencing. It's important to address these concerns, especially given your history of myopia and the presence of floaters. Let's break down your questions and provide some insights.

1. Flashes of Light: The flashes of light you are experiencing when looking to the left or right can be indicative of several conditions, including vitreous detachment or retinal issues. In individuals with high myopia, the vitreous gel can detach from the retina, leading to flashes of light, especially during eye movement. This is often referred to as "photopsia." While flashes can sometimes be associated with retinal detachment, they are more commonly linked to vitreous detachment, particularly if there are no accompanying symptoms like a sudden increase in floaters or a shadow in your peripheral vision.

2. Nature of Flashes: The flashes you describe, which occur primarily during eye movement, are characteristic of vitreous traction on the retina. When you turn your head or eyes, the vitreous gel can tug on the retina, causing brief flashes of light. If you are not moving your eyes and still see flashes, it may warrant further investigation. However, if the flashes are only present during movement, it is likely related to the vitreous.

3. Severity of Symptoms: The fact that you are experiencing flashes in low-light conditions and not in bright light is not uncommon. However, it is crucial to monitor these symptoms closely. If the flashes become more frequent, or if you notice a sudden increase in floaters or any shadow in your vision, it is essential to seek immediate medical attention, as these could be signs of retinal detachment.

4. Care and Management: To help manage your symptoms and potentially prevent worsening, consider the following tips:
- Regular Eye Exams: Given your high myopia and current symptoms, regular check-ups with an eye care professional are essential. They can monitor any changes in your retina and vitreous.

- Eye Rest: Ensure you give your eyes adequate rest, especially if you spend long hours on screens. The 20-20-20 rule is helpful: every 20 minutes, look at something 20 feet away for 20 seconds.

- Healthy Lifestyle: Maintain a balanced diet rich in antioxidants (like vitamins A, C, and E) and omega-3 fatty acids, which are beneficial for eye health. Staying hydrated is also crucial.

- Protective Eyewear: When outdoors, wear sunglasses that block UV rays to protect your eyes from potential damage.

- Limit Eye Strain: If you are experiencing discomfort or fatigue, consider reducing screen time and ensuring proper lighting when reading or working.

In conclusion, while your symptoms may not currently indicate a severe issue, it is vital to remain vigilant. Keep track of any changes in your vision and consult with an eye care professional if you notice any new symptoms or if your current symptoms worsen. Early detection and management are key to preserving your vision, especially with your history of myopia. Take care of your eyes, and don't hesitate to reach out to a healthcare provider for personalized advice and treatment options.
