Yes, however it is to your advantage to use a participating provider. First, you can take advantage of additional discounts our panelists provide. Second, if you have a problem, the UFT Welfare Fund will help resolve any issues. With a non-participating provider, you are required to pay the full cost of the service and then, within 90 days, submit an itemized paid receipt and a copy of the prescription along with a validated optical certificate to the Fund for payment. You will be reimbursed $125 or the actual charge, whichever is less.
