With the large-scale automation that's now possible, cheap contact lenses can made with consistent high quality despite their low price. The plastic that's used for the lenses is very advanced, but it's easily formed. And although the precision achieved is remarkable, lens machinery can turn out thousands of cheap contact lenses as easily as it can one.

When you're dealing with your health, it doesn't make sense to take chances with it by using substandard products. And with cheap contact lenses, you don't have to. A contact lens is considered a medical product much like a plastic heart valve. And the contact lens makers produce and sell the same quality lens to everyone.

The mass production of contacts is one reason for the low price of cheap contact lenses. And another reason is the standard sizes used for soft contacts. RGP lenses are less flexible and must be custom fitted. But soft contacts mold to the wearer's eye which smooths out any minor shape variations. So once the prescription is known and a size is selected, there's usually not a problem with the fit.

The Internet has not only made vast amounts of information available to everyone, but it's also made it very efficient to do business. And buying cheap contact lenses online is one result. Without the usual overhead of a local store, online stores are able to offer you lower prices. And when a company like 1800Contacts buys in such large volume, it gets the best price from the lens maker and can pass the savings on to you.
