Is there a surgery to help my big eye/little eye situation? (Photo)

Thanks for sending a photos with your questions. There is asymmetry between your two eyelids and it would be necessary to take a detailed history and assessment of your eyes before determining both a diagnosis and treatment plan. Although there is a suggestion of a droopy eyelid, termed ‘ptosis’ it would be prudent to have a consultation to discuss this in person. My suggestion is that you do research and schedule a consultation with an oculo-facial plastic surgeon experienced in both blepharoplast and ptosis surgery.

You appear to have left upper eyelid ptosis (drooping), but the photos do not let me assess this for certain.  Without an exam, it will not be possible to fully evaluate you and give you recommendations.   Be sure to discuss your goals and concerns with your board certified plastic surgeon and consider the pros and the cons. Be certain your surgeon is properly certified.  I've attached a link where you can start your search. 

There are several reasons for eye asymmetry and several treatment options. See following video. A consultation is needed to properly evaluate your eyes and determine the cause(s) of eye asymmetry. Skype consult available.

Thank you for your question and photos!
The short answer is yes, this can definitely be improved.
The longer answer is, I would recommend an in-person evaluation with an oculoplastic surgeon to sort out whether a simple ptosis repair or a more involved orbital surgery would be best to improve your symmetry. Ptosis repair would simply raise your left upper eyelid, while an orbital decompression would be used to make your right eye less prominent. Every person's situation is different, but there is definitely a good solution for you.
Best of luck!!
