It's important to understand the terminology:

• Disposable lenses = replaced every two weeks, or sooner
• Frequent replacement lenses = replaced monthly or quarterly
• Traditional or reusable lenses = replaced every six months or longer

The term "disposable" often collectively refers to both disposable and frequent replacement lenses.

How Different Are Disposables from Regular Lenses?

Even before the advent of disposable lenses, it was well known that frequent lens replacement was a healthy thing to do. Problem was, contacts were too expensive to discard very often ? so various cleaning solutions and devices were used to prolong the life of the lens.
Then contact lens manufacturers developed new manufacturing methods to produce high-quality lenses in greater volume, at lower cost. These advances led to lower lens prices, making it affordable to replace lenses more often. Some of today's disposable lenses are made of the same materials as traditional lenses; other disposables are made from new materials developed especially for disposability.

Colored contact lenses can add some interest to your vision correction. In fact, some people wear them as an accessory
even people who don't need contacts to see better! If you do need contacts to correct your vision, the ability to buy colored ones can make being nearsighted a bit more fun. Here's some tips on how to choose colored contacts.

Contacts have come a long way from the hard contact lenses that first appeared after World War II. In recent times, there has been many advances in comfort and quality. From the soft contacts with the added comfort to disposable contacts with the added convenience, contacts have been a reliable method of vision correction for over 50 years.

One of the more fun advancements in contact lenses has been the colored contact lens. With colored contacts you can completely change the color of your eyes, or simply add a tint to the color you already have. You can have a collection of colors so that you can have blue eyes when it suits you and green eyes on the other days. You can even change your eyes to a striking violet color!

There are 4 different types of colored contacts and these contacts are available for wearers who need no eye correction and also for those that have astigmatism as well as those that need bifocals. They also come in disposable wear as well.
Visibility tint contacts are more for convenience than for changing eye color. These contacts are lightly tinted and are mainly s that you can see them easily. Anyone that has ever dropped a contact, will agree that trying to find them is almost impossible, but visibility tints make this much easier. This tinting does not really change the color of your eye.
