The symptoms seem to suggest that there's a transmigration of the free body of the eye, which can lead to blindness, depending on where the vision is dimmed or distorted, and it's important to get a doctor's attention immediately if you have a problem with your vision.
Doctor, there's been some symptoms in my recent eye, and I'm afraid I'm going to be blind because there's some other symptoms in my vision, so can you tell me what's wrong with my eye?
