My Eyes Are Completely Different Size, Shape, Vision? (photo)

I agree that you definitely need an in-person evaluation to determine how to improve the symmetry of your eyelids. In terms of your pupil, a custom made contact lens can definitely help. The lens can be colored to match the shape of the pupil in the other eye and should also help reduce the amount of red eye in photos.

Based on this photo, it is not entirely clear whether it is simply a droopy eyelid [ptosis] which is causing you to have a "smaller left eye", or whether it is possibly the position of the eyeball and the underlying bony eye socket which could be contributing to this asymmetry.

An in-person examination by an oculoplastics surgeon  is very important in your case. The position of the eyeball and the eyelid function can be assessed properly. A CT scan of the face/orbit may be required to rule out underlying bony asymmetry depending on the examination.

You can find an Oculoplastics specialist near you by going to the link I have provided below.

Also, since you have very dark irides, your pupil abnormality is not obvious. Though pupil surgery can be performed, it is likely not worth the risk for you.

Mahalo for your pictures.  There's not much that can be done about the pupil and cat's eye reflex in photos, but the lid margin can be adjusted quite effectively with or without an external incision.  Talk to your surgeon about these options.
