Nit: An optometrist is usually fine if all you need is a refraction.
It's when you're dealing with something that requires medical intervention (glaucoma, pars planitis, etc.) that you need to shell out for an ophthalmologist. An optometrist can still catch that stuff, but will need to refer you for treatment.
