Fixing an eye that looks smaller depends on the cause. Non-surgical options include Botox or fillers to balance muscles and volume around the eyes. For bigger differences, surgery like blepharoplasty can correct drooping eyelids or remove extra skin. If the asymmetry is due to a condition like ptosis or thyroid eye disease, treating that condition with medication or therapies may help. Consult an eye doctor or an oculoplastic surgeon for a tailored treatment plan.
