Hello! Thank you for sharing your concerns regarding your vision and eye health. Based on your description, it seems you are experiencing several visual phenomena, including flickering lights, the perception of shimmering points in the sky, and issues with focusing. Let’s break down these symptoms and explore their potential causes and implications for your eye health.

Firstly, the flickering lights and shimmering points you see when looking at the sky or bright surfaces can be related to a few factors. One common explanation is related to the way our eyes and brain process light. When you look at a bright, uniform surface like the sky, your retina may pick up on slight variations in light intensity, leading to the perception of flickering or shimmering. This phenomenon can be more pronounced in individuals with high myopia (nearsightedness), like yourself, as the structural changes in the eye can affect how light is focused.

Additionally, the presence of floaters (or "flying spots") is a common occurrence, especially in individuals with high myopia. Floaters are tiny clumps of gel or cells inside the vitreous humor of the eye that cast shadows on the retina, which can be perceived as spots or lines. The fact that you see a consistent white line in your left eye could indicate a specific floater that is more prominent in your field of vision. While floaters are generally harmless, any sudden increase in their number or changes in your vision should prompt a visit to an eye care professional.

Regarding your difficulty focusing, this could be attributed to several factors. It’s possible that your eyes are experiencing fatigue, especially if you are spending long periods reading or using screens. Eye strain can lead to symptoms such as blurred vision, difficulty focusing, and a feeling of heaviness in the eyes. It’s important to take regular breaks using the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. This can help alleviate some of the strain on your eyes.

The fact that you notice these symptoms more during the day and less at night could be related to lighting conditions. Bright light can sometimes exacerbate visual disturbances, while dimmer light may reduce the contrast and make these symptoms less noticeable. However, if you find that your symptoms persist or worsen, it is crucial to seek further evaluation from an eye care specialist.

In terms of your concern about potential underlying issues, it’s reassuring that you have undergone multiple eye examinations, including retinal assessments, which have not indicated any serious problems. However, if you continue to feel uneasy about your symptoms, consider seeking a second opinion from a different eye care provider. They may offer additional insights or testing that could help clarify your situation.

Lastly, regarding your question about eye size and the feeling of one eye being weaker, this could be a result of muscle fatigue or imbalance, especially if you are straining one eye more than the other. If you notice significant differences in vision or eye appearance, it’s essential to discuss this with your eye doctor.

In summary, while some of the visual phenomena you are experiencing can be common and benign, it’s important to remain vigilant about any changes in your vision. Regular eye exams and open communication with your eye care provider are key to maintaining your eye health. If your symptoms continue to cause concern, don’t hesitate to seek further evaluation. Your vision is important, and addressing these issues can help ensure your eyes remain healthy. Thank you for your questions, and I hope this information helps clarify your concerns!
