Your vision plan should cover an annual comprehensive eye exam, frames or contacts, and lens enhancements. Other things to consider are how often you want new glasses and your overall frame allowance. Some plans may highlight low rates, but provide an overall low frame allowance, or don’t provide a lot of savings on lens enhancements (where costs can really add up). Plus, you’ll want to make sure the doctor network includes convenient locations. Read the plan details to ensure you’re getting the right plan for your needs.
