It is best to see an eye doctor for correct diagnosis and treatment soon

Strabismus is something that should be evaluated promptly. Permanent, irreversible, vision loss (amblyopia) can result if not addressed at a young age (up to 7 or 8 years old). Treatments can include glasses, prisms, and surgery. Amblyopia can be treated with drops or by patching the "good" (better seeing) eye.
