I don't know the answer to that question, but I can hypothesize. The eyelid speculum changes the eyelids in some individuals. This speculum is used during surgery to keep the eyelids open. You probably still are healing from the speculum. Is the eyelid somewhat droopy? If so, then this is probably the answer. I wouldn't worry too much about the discomfort unless there's extreme redness, fever, or swelling of the eyelid.

The eyelid is a little droopy but it isn't red or swollen so I guess it's ok. Very, very sensitive to bright lights too. :(
