What are my options to cosmetically fix strabismus at 24yr?

Mostly surgery. Your eyes are out of position and i assume you are having single vision. This means one of the eyes sees less well and therefore can drift out of alignment. If the angle of misalignment is small, a prism can be introduced into your eyeglasses to given an apparent straightening. But if more major, then eye muscle surgery must be done. Not a big deal. See your ophthalmologist.
