What is a Flexible Spending Account?
A Flexible Spending Account (FSA) is a fund which allows you to pay for eligible medical expenses with pre-tax money. This might be a fund that is set up by your employer and allows you to set aside money on a regularly basis which you can use towards health insurance co-pays, bandages, contact lenses and contact lens solutions etc.

How to use your Flexible Spending Account to buy contact lenses

You can purchase products using your Flexible Spending Account (FSA) funds—just use your FSA card as you would any other credit card. If you don’t have an FSA card, you can purchase products using a regular credit card and submit the invoice for reimbursement.
How to Buy Online
Before you are ready to buy online, ensure you have an up-to-date prescription. The prescription should have details of your doctor’s name and phone number.

Compare different retailers for the best price but don’t purchase solely on price. Take into consideration the following before making your decision:

1. Does the company have phone support? If you have a problem you may wish to talk to someone verbally.
2. Does the company have a returns policy?
3. How long before the order is shipped?
4. Do they have a secure website for purchasing with your credit card?
5. Check the shipping charges. Some online retailers may offer free shipping on large orders, others may not. Factor this cost into the total charge when making your decision.
