My one eye is drooping for some reason. Any suggestions? (photos)

Droopiness of the eyelid could be caused by a variety of factors. Our studies have demonstrated that wearing contact lenses may cause eyelid ptosis. Regardless, it could be corrected unless it is part of a generalized muscle disease, which it is extremely rare. While your picture are not optimal for the assessment, you most likely have eyelid ptosis on both sides and it is not noticeable on the right side because of 2 reasons. One reason is that you most likely are recruiting your forehead muscle to lift the right eyelid which also raises your right eyebrow. The second reason is that your right eye (the globe) is sightly more forward on the right compared to the left. This type of asymmetry is extremely common. You need to consult a plastic surgeon who is familiar with these matters and eyelid ptosis correction. 

Thank you for your question and photo.  You have eyelid ptosis or drooping on the left.  This is usually caused by loosening of one of the eyelid muscles.  TIghteing of that muscle under local anesthesia is effective for addressing this problem.  Best wishes.

You have a ptosis of the left upper eyelid.  See an oculoplastic surgeon who can evaluate your eyelid muscles and decide what would be best to elevate the low lid.
