My eye is severely bigger than the other? (Photo)

You have eye asymmetry which is likely due to the following: 1) left upper eyelid ptosis (droopy eyelid);  2) left eye more sunken (or right eye more bulging).  You need to see an oculoplastic specialist for evaluation.  See video and link below.

Hello 

There are many things that can cause the uneven or asymmetric
appearance you are seeing.  First it is important to determine if the bony
structure around the eye or the
tissue behind the eye has been changing.  This could cause one eye to look
sunken or the other to look prominent.  You have have some asymmetry in the soft tissue or the eyelid itself and this can cause one to look
asymmetric.





The first step is to seek an opinion from an oculoplastic
surgeon as to the cause of they asymmetry and make sure it is not behind the
eye.  But yes there are many options depending upon the cause

There can be many causes for one eye bigger than the other.  You may have ptosis (drooping) of the smaller eye, which is what it appears you have.  It is possible your right eyelids are retracted and/or your right eyes is proptosis (bulging) outward stretching the right eyelids apart making the eye seem bigger.  If you are having any eye socket pain or having double vision then I would see an oculoplastic surgeon.  If your eyes and sockets check out okay then a ptosis surgery to lift your left upper eyelid more open would improve symmetry.  This can be done in the office setting.  Sometimes when there is marked asymmetry it is possible that lifting one eyelid will cause the other side to droop because of something called Herring's law of equal innervation that your surgeon should test for and discuss.  Best regards.
