What can be done about my left eye? (Photos)

The photos demonstrate left upper eyelid ptosis.  A thoughtfully performed ptosis repair and blepharoplasty should be able to make the left side look much more like the right side.  The assessment you need for this cannot be accomplished by Skype consultation.  A detailed in person assessment is essential.  I recommend using the American Society for Ophthalmic Plastic and Reconstructive Surgery website and its directory to help you find a well qualified surgeon close to home.

It appears you have left upper eyelid ptosis along with enophthalmos (sunken eye). There are solutions for both but ptosis is easier to address. See following link. See an oculoplastic specialist for evaluation.

You have left eye ptosis which could be corrected with ptosis repair. This is a procedure that will elevate the eyelid so that it appears more open, improve vision, and create a more desirable symmetrical appearance. Good luck!

You have a ptosis of the left upper lid.  There may be other things going on with the size of the eye or the socket but can't tell from a picture.  See an oculoplastic surgeon.  They can evaluate the eye and the eyelid muscles to determine if the lid can be elevated to improve symmetry.
