Disposable Contact Lenses – A Quiet Revolution In Eye Care

Did you know that contact lenses have been there for over a 100 years? Since then, there have been several advancements leading to the fact that today almost anyone can wear contact lenses. That's why today, there are many and more advanced contact lens options for you than ever before.

The first step to take if you want to buy contact lenses is to see an eye care professional or ECP. After evaluation of your vision, he can help you determine the most suitable contact lens for your eyes.

One of the most popular options in contact lenses is disposable contact lenses. Introduced in 1987, these lenses are worn only for a specific period of time after which they are disposed off and replaced with a fresh pair. Due their many health and comfort benefits, daily wear contact lenses are now recommended by even ECPs.

Commonly available, these daily disposable contact lenses come in high quality and are reliable and cheaply priced. You can find them in a wide range of types, colors, and styles. However, you must seek the advice of your ECP to understand these lenses and be better informed on how to use and take care of them.

What Are Disposable Contact Lenses?

Before you start shopping around for daily wear contact lenses, you need to understand the terminology involved. Here are the three main types of frequent replacement contact lenses:

1. Disposable lenses - they need to be replaced daily, weekly or every two weeks 2. Frequent replacement lenses - they need to be replaced monthly or every three months 3. Traditional or reusable lenses - they need to be replaced once in every six months or yearly

Materials Used For Contact Lens

Contact lenses can be classified into three types depending on their material such as:

Hard lenses - made using PMMA or Plexiglas or Lucite. These lenses have become very rare now. Soft lenses - made from water-based gel-like plastics. These daily wear contact lenses are the most popular type. GP lenses or RGP or "oxygen permeable" lenses - made from hard, waterless plastic they are used by people suffering from presbyopia and high astigmatism.

Since the introduction of the Acuvue Contact Lenses or the daily wear contact lenses in 1971 to now, the lenses were made from "hydrogel" plastics but now a new silicone hydrogel is used to make these contact lenses and it allows higher amount of oxygen to pass through via the lens to your eyes keeping them hydrated.

Difference between Disposables and Regular Lenses

Any lens wearer knows that replacement of lens frequently is a healthy habit. But since contact lenses were expensive, changing them very often burnt a hole in the pockets. And cleaning solutions helped to increase the life span of these lenses.

However, with large quantities of high quality contact lenses at a low cost being manufactured, lenses have now become more affordable and slowly being replaced with daily wear contact lenses.
