The sales of contact lenses are regulated by the Food And Drug Administration and the Federal Trade Commission. Now it s easy to order the perfect contact lenses online at a great discount. Ophthalmologists are eye surgeons who study and treat eye diseases and can also perform the duties of optometrists. Optometrists examine eyes, diagnose and treat vision problems, and prescribe eyeglasses and contact lenses. In most states they can also prescribe medicine. Opticians grind and dispense eyeglasses and in some states dispense contact lenses.

You ll want to take some simple precautions to make any lens purchase safe and effective. And all correcting contact lenses must have a valid prescription from an ophthalmologist or optometrist.

If you plan to wear contact lenses for more than 18 hours for the purpose of changing your eye color then buy colored soft lenses. You can mark rigid lenses in a way to show which lens is for which eye. They don t rip or tear, so they are easy to handle. Soft lenses are much easier to adjust and are much more comfortable than rigid lenses because they conform to the eye and absorb and hold water.

Soft lenses also come as disposables, used once and discarded, or as planned-replacement lenses. Rigid gas permeable contact lenses are durable, resistant to deposit buildup, and generally give a clearer, crisper vision. In some model lenses, each lens corrects for near and distance vision and in others, one lens is for near vision, and the other for distance.

There are several types of lenses in the marketplace today including soft contact lenses, rigid gas permeable lenses, extended wear lenses and disposables. Keep in mind contact lenses are often more complex than appears. The expiration date for your prescription is currently set by your state requiring a one-year or two-year renewal. If your state hasn t set a minimum expiration date, government regulation sets a one-year date unless your eye doctor determines there s a medical reason for an expiration date of less than one year.

Disposable lenses don t come with instructions for cleaning and disinfecting. But those lenses labeled specifically for planned replacement do. Extended wear lenses are usually soft contact lenses made of flexible plastics that allow oxygen to pass through to the cornea.

Check out any rebates that may be available from the seller, from the manufacturer, for first-time contact lens wearers and for individuals who buy lenses and get an eye exam. Beware of attempts to substitute a brand that is different from the one you want when buying contacts. Ask about discount prices at your doctor s office when you have your eye examination, or during a follow-up visit after you get your prescription.

Always buy from a reputable company. You can buy contact lenses without a prescription, but the company would be selling you a prescription device as if it were an over-the-counter device violating FTC regulations - selling you contact lenses without actually having your prescription. And when you receive your order, if you think you ve received an incorrect contact lens, check with your doctor or eye care professional right away don t accept any substitution unless your eye care professional approves it. There are many good contact lens retailers now on the Internet making their lenses available at a discount for both prescription and non-prescription lenses.

If you have an insurance plan, the insurance plan s seller s prices may or may not be better than what you can find elsewhere. This should be just one option when you re shopping for contacts. Check to see if your health insurance plan includes vision coverage. Compare prices and get quotes from two or three online and offline suppliers.

To be sure your eyes remain healthy you shouldn t order lenses with a prescription that s expired or stock up on lenses just before the prescription is about to expire. It s much safer to be re-checked by your eye doctor. Interesting note: when the eyes are open, tears carry adequate oxygen to the cornea to keep it healthy, but during sleep, the eye produces fewer tears, causing the cornea to swell. And the risk of corneal ulcers for people who keep extended-wear lenses in overnight is 10 to 15 times greater than for those who use daily-wear lenses only while they re awake.

A basic rule: never swap your contact lenses with anyone else. And the most serious safety concern with any contact lens is from overnight use. Replace your contacts as recommended by your eye care doctor because they wear out as time goes by.

If you re looking for cheap contact lenses, you may find that cheap materials or other ways of cutting costs will affect the quality you want. Remember to use only contact lenses that are FDA-approved and only if prescribed by a licensed eye care professional. Ordering discount contact lenses online has never been simpler with, and sometimes without, a credit card.
