Vision Insurance in Nevada is relatively similar between plans and even between insurance companies. At a minimum, it should cover at least one annual visit to your optometrist. The plan may cover new frames and lenses every year or every other year, based on the plan choice. The less frequently you go to the optometrist and buy new lenses, the lower the plan cost.
VSP vision insurance has a large network of providers here in Nevada. In addition, VSP has a national doctor list, meaning your coverage follows you outside of the state.
