If you have an FSA or HSA debit card, you can enter that card's information at check-out, just like you would a normal credit card. If you do not have an FSA or HSA debit card, you will have to make your purchase using another credit card and seek reimbursement directly from your FSA or HSA provider. Most FSA or HSA providers will require you to submit a reimbursement form along with an itemized receipt. We will email this receipt to you along with your purchase confirmation. At this time, Cirrus Eyewear is not able to bill your insurance directly for your purchase.
