What an eye exam costs around Mason City

No prices exist in the NPI registry, so treat the list below as a call sheet rather than a quote sheet. Nationally this site puts an eye exam at about $136 without insurance and around $25 with a vision plan.

No national retail optical brand is registered under its own name in this metro, so expect the independent optometry band of $120 to $200 rather than the $50 to $110 retail band. A comprehensive exam is $100 to $250, and adding a contact lens fitting takes the visit to $150 to $370.
