FDA Approved Contact Lenses Supplier

Unfortunately not all online retailers are compliant with FDA regulations, in fact most aren't even registered even though they claim to be. To ensure your chosen online retailer is compliant you can speak direct to the FDA to insure this is the case - http://www.fda.gov/  

If you are not sure, ask for the retail store for their 510K number, once received then you can check with the FDA to confirm they are registered.  A 510K number is registered with the FDA and insures that the retailer has to have this number, if the FDA state the online store or retailer is not known to them, Do not purchase. Inform the FDA as this is an illegal offence.

There are a few do's and don't's when buying or wearing contact lenses, either from online stores or from shops, malls or flea markets. 

1. If you don't have a prescription for your lenses the seller is breaking US laws in supplying you.

2. Orders outside of the US are not subject to having a prescription, this will vary from country to country.

3. Don't share your contact lenses with anyone, they might have an eye infection.

4. If you eyes become sore, red or agitated, take the lenses out with clean hands and seek medical advice.

As with all contact lenses, decorative lenses or cosmetic lenses always insure you visit your professional eye care optician at least annually.

FTC Regulation

What does it mean for you? The Federal Trade Commission (FTC) act came in force in 2004. Along with giving the consumer more rights the act extended to lens prescribers and sellers, and required the Federal Trade Commission (FTC) to develop and enforce implementing the rules. 

Under the Rule issued by the FTC, contact lens prescribers - defined as anyone permitted under state law to issue prescriptions for contact lenses, which include ophthalmologists, optometrists, and licensed opticians who are permitted under state law to fit contact lenses (sometimes called dispensing opticians) must give a copy of the contact lens prescription to the patient at the end of the contact lens fitting, even if the patient doesn't ask for it. Prescribers must also provide or verify the contact lens prescription to anyone who designated to act on behalf of the patient, including contact lens sellers. Prescribers are also barred from requiring patients to buy contact lenses, pay additional fees, sign waivers or releases in exchange for a copy of their prescription, or disclaim liability or responsibility for the accuracy of an eye examination.


The Fairness to Contact Lens Consumers Act (FCLCA) became law on February 4, 2004. The Act mandates that eye care practitioners, including optometrists, release contact lens prescriptions to their patients. It also requires contact lens sellers to verify the validity of contact lens prescriptions before releasing contact lenses to consumers.

RX System For US Customers ONLY

The Rx Verification process is mandatory in the United States in order to place orders for contacts with or without a prescription. When a customer reaches the final stages of the checkout process, the customer will be asked to either select his or her doctor or to enter the doctor’s information. Once all information is received, the Rx Verification system will then pick up the order and request an approval by phone from the doctor to approve the customer’s prescription. The doctor has 8 hours to approve or deny a customer’s prescription. If a doctor does not approve or deny a prescription within the 8 hour time frame, the customer’s prescription will be approved with a receipt of approval sent virtually to the contact lens supplier that will that release the order from shipping. All orders are filled within 24-hours unless denied by a customer’s optician.   

The RX System has been developed to insure our customers receive the correct information. The Fairness to Contact Lens Consumer Law (FCLCA)  became law as of February 4, 2004, all of what of FourEyez communications to eye care providers regarding prescription verification are regulated in detail.
