A refraction is a measurement of the lens power necessary to prescribe glasses or other corrective lenses. Many medical plans, including Medicare and Medicare supplements/replacement plans, do not cover refractions. If your insurance company does not pay for this service, you are responsible for this charge of $76. It is ultimately your decision whether or not you need a refraction so if you know you don’t have coverage for one unless you really need a new prescription, just let our technicians know at the beginning of the visit that you don’t want a refraction done.
