Is there anyway to fix my different sized eyes? (photo)

Your right eye appears more bulging with lower eyelid more retracted (vs.left eye more sunken). There are procedures to improve the symmetry. See following video and website link. Skype consult available.

unfortunately most asymmetry around the eyes tends to worsen as we get older. The good news is that you would be a great candidate for Botox to both the left upper and lower lids.  The Botox would elevate the upper lid and lower the lower lid leading to a widening of the eye. An oculoplastic specialist would be best as this is a delicate area that needs very precise injections. Hope this helps and best of luck.

By different size eyes, are you referring to your eyes being positioned differently in the bony orbit, one eye being larger than the other (i.e. axial myopia), or appearing different in size due to eyelid asymmetry?  These questions can be answered with a thorough examination.  In general, changing the position of the upper and/or lower eyelid surgically may improve the asymmetric appearance of the eyes.
