My Wife has been feeling that her left eye seems little small and eye lids feel heavy. She is putting drops also. What could be the reason? Vision is fine and she is sleeping alright since last 2-3 days also.. What could be the cure? Could it be because of other medicines she is taking to regulate her menstrual cycles and increase blood flow? Could it be because of tiredness? What else? Could it just be in her mind or what? Is it because of dryness? Whats the instant cure and long term cure and reason??? She is very irritated and feeling hassled and thus the query.
