Currently, Americans in all 50 states can buy contacts both from ECPs and other sources such as optical chains, warehouse clubs and online stores. This privilege originates from a 2004 legislation that patients are entitled to obtain a copy of contacts prescription from ECPs without extra cost, which was only available in certain states before that time. This law profoundly separated fitting and lenses buying. You will never be forced to buy contacts from ECPs after been fitted. Today, contacts prescriptions are just like ones of other medical products like medicines that may provide more information than eyeglasses prescriptions. With a prescription, customers can buy disposable lenses regularly.
