Among the many kinds of contact lenses you can buy are: novelty, colored, crazy, Halloween, special effects, theatrical, costume, scary, glow in the dark, wild eyes, mirrored, black, white, and red. Before you buy contact lenses from anyone other than your eye care professional, it pays to be a wise consumer. Contact lens sales are regulated by the FDA (Food And Drug Administration) and the FTC (Federal Trade Commission.)

There are 75 million contact lens wearers worldwide and 31 million in the U.S. alone. If you’ve always wanted to change your eye color, color contact lenses can provide baby blues, gorgeous greens, heavenly hazels — even various patterns and designs.

Bifocal correction is possible with both soft and rigid lenses. Keep in mind contact lenses are often more complex than appears to be. Disposable lenses don’t come with instructions for cleaning and disinfecting, while those labeled specifically for planned replacement do.

Extra-thin soft lenses are on the market for very sensitive people. Soft lenses are easier to adjust and are much more comfortable than rigid lenses, because they conform to the eye and absorb and hold water. Contacts provide for excellent peripheral vision for sports, driving, safety, and performing.

Although easier to handle and less likely to tear, rigid gas permeable lenses are not as comfortable initially as soft contacts and it may take a few weeks to get used to wearing the RGPs, compared to just a few days for soft contacts. There are two general categories of contact lenses - soft and rigid gas permeable. 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 less than one year.

With planned-replacement lenses, the doctor works out a replacement schedule tailored to the needs of each patient. While the ability to hold water increases the oxygen permeability of soft lenses, it increases their fragility quotient as well.

Beware of attempts to substitute a brand different from the one you want when buying contacts. Buy your contact lenses from a supplier you’re familiar with and know is reliable or has name familiarity Check to see if you have a health insurance plan that includes vision coverage.

Always buy from a reputable company; you can buy contact lenses without a prescription, but the company is selling you a prescription device as if it were an over-the-counter device violating FTC regulations by selling you contact lenses without having your prescription. There are many good contact lens retailers now on the Internet making their lenses available at a good discount for prescription and non-prescription lenses. 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.

When you place your contact lens order, request the manufacturer’s written patient information for your contact lenses; it’ll give you important risk and benefit information as well as instructions for use. Get a feel for how the retailer handles customer service calls; in case you have a problem after your order arrives. Wherever you buy, shop for quality and value and don’t forget you want to do what’s best for your eye health.

One sight-threatening concern is the infection Acanthamoeba keratitis, which is caused by improper lens care; this difficult-to-treat parasitic infection’s symptoms are similar to those of corneal ulcers. Be aware that extended-wear (overnight) contact lenses - rigid or soft - increase the risk of corneal ulcers, which are infection-caused eruptions on the cornea that can lead to blindness; symptoms include vision changes, eye redness, eye discomfort or pain, and excessive tearing. Getting a proper fit is essential; contact lenses that are poorly fitted can lead to eyesores, eye inflammation, and eye abrasions.

Under the binding down of a rigid contact lens during sleep, the flow of tears and oxygen to the cornea is reduced; lack of oxygen leaves the eye vulnerable to infection. Soft extended-wear lenses bind down on the closed eye, but they are porous and allow some tears through during sleep; because they have so little form, their binding has very little effect on the shape of the eye. Microorganisms may be present in distilled water, so always use commercial sterile saline solutions, if you plan to use enzyme tablets in water for disinfection.

Ordering contact lenses online has never been simpler with, and sometimes without, a credit card. 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’ll want for your precious eyes. It’s becoming easier and easier all the time to shop online and often the shipping is free.

With a contact lens prescription in hand, it’s possible to buy your contact lenses from stores, the Internet, over the phone, or by mail. There are 75 million contact lens wearers worldwide and 31 million in the U.S. alone. All correcting contact lenses must have a valid prescription from an ophthalmologist or optometrist.

The choice of which lens is right for you should be based only on an examination by your doctor or eye care professional, not over the phone. Contact lens sales are regulated by the FDA (Food and Drug Administration) and the FTC (Federal Trade Commission.)

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 less than one year. Extended wear lenses are usually soft contact lenses; made of flexible plastics that allow oxygen to pass through to the cornea. People who have good distance vision but need help for reading can get a monovision reading lens for one eye.

In some models, each lens corrects for near and distance vision and in others, one lens is for near vision, and the other is for distance. Soft lenses also come as disposable products, that is, used once and discarded, or as planned-replacement lenses. While the ability to hold water increases the oxygen permeability of soft lenses, it increases their fragility quotient as well.

Rigid gas permeable contact lenses are more durable, resistant to deposit buildup, and generally give a clearer, crisper vision. Although easier to handle and less likely to tear, rigid gas permeable lenses are not as comfortable initially as soft contacts and it may take a few weeks to get used to wearing the RGPs, compared to just a few days for soft contacts. If you plan to wear lenses for more than 18 hours for the purpose of eye color change, then buy colored soft lenses.

Bifocal correction is possible with both soft and rigid lenses. Rigid gas permeable lenses tend to be less expensive over the life of the lens since they last longer than soft lenses.

Rebates 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. When you place your contact lens order, request the manufacturer’s written patient information for your contact lenses; it’ll give you important risk and benefit information as well as instructions for use. 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.

Check out how long the online supplier has been in business before you buy. Ask about prices at your doctor’s office when you have your eye examination, or during a follow-up visit after you get your prescription. Focus on value, not just the price; most people looking for the best price are really looking for the best value.

You can buy contact lenses from an eye doctor, on the Internet, from an optical store or a warehouse club. Buy your contact lenses from a supplier you’re familiar with and know is reliable or has name familiarity. When you place your order make sure your lenses are available and not out of stock, because you’ll need them now.

Don’t wear lenses any longer than they’re prescribed for, nor when sleeping unless you are otherwise directed. Basic rule: never swap your contact lenses with anyone else. 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.

One sight-threatening concern is the infection Acanthamoeba keratitis, which is caused by improper lens care; this difficult-to-treat parasitic infection’s symptoms are similar to those of corneal ulcers. Be aware that extended-wear (overnight) contact lenses - rigid or soft - increase the risk of corneal ulcers, which are infection-caused eruptions on the cornea that can lead to blindness; symptoms include vision changes, eye redness, eye discomfort or pain, and excessive tearing. The use of homemade saline made by using salt tablets mixed in water is one of the biggest contributors to Acanthamoeba keratitis in contact lens wearers: the FDA no longer condones the use of salt tablets.

If you lead an active lifestyle, contact lenses can provide you with close to natural vision. Make sure to visit a reputable eye doctor for a complete eye examination once a year, or more frequently if needed. If you prefer the way you look without glasses or find glasses to be cumbersome and awkward, contacts can provide the ease, convenience and comfort you need.
