Many people use their FSA funds for CraftOptics! Plans do vary, but if you have a Visa card associated with your FSA, you can typically use it as we are a merchant with an inventory information approval system (IIAS), which indicates FSA-eligible items (all our vision products) and then permits only those items to be charged to the card.
Some vision plans also offer reimbursement for all or a portion of CraftOptics purchases. We do not process insurance plans but we do provide detailed receipts for documentation and reimbursement. Check with your plan for details.
