I have a swelled upper eye lid on just one of my eyes that closes off part of my eye, causes the eye to be watery and causes minor pain in the eye itself. But my biggest question is whether that could be the cause of my sudden terrible vision? I could only read the top line of an eye chart with covering each of my eyes. The top line only! Both eyes were terrible. The urgent care doctor today said to put hot cloth on the eye, apply hydrocortisone cream to the external eye lid, and put antibiotic drops in the eye for a possible eye infection. Plus she said to see an eye doctor for my terrible vision within the next 3 days! Is it urgent to get my eyes checked right away which could be difficult to get an appointment that fast? The eye lid suddenly got bad today along with my poor vision just today. What could account for my sudden poor vision?
