EyeMed maintains a nationwide network of participating providers who have agreed to accept EyeMed's allowances for exam and lens services. You can maximize your vision benefits when you visit one of EyeMed's participating providers. Certain services, such as medically necessary contact lenses, are paid in full. An allowance is available for elective contacts and discounts are available for many other vision services. You may also choose a provider outside the network and be reimbursed for part of the cost. Note that there are limits on how often you can receive benefits.
