Different Types Of Contact Lenses

Different Types Of Contact Lenses

By Dr Wei


A couple of years ago, I went to get fitted for contact lenses. It was the first time I ever attempted to use lenses and was a bit nervous. The millions of choices for different types of contact lenses did nothing to alleviate my stress levels.. The eye doctor claimed I could possibly opt for hard lenses or soft lenses. If I wanted, I could even transform my eye color to green or grey.

With so many choices, buying contact lenses can be very confusing. This article should help you navigate through some of the terms commonly used.

The original lens was called Gas permeable contact lenses. These give numerous benefits to the wearer and are also known as hard lenses.

Hard lenses are made in a way that allows more oxygen to reach the eye. This has an important role in preventing eye diseases and eye problems. If you are a contact lens wearer who is prone to eye infections, hard lenses might help solve your problem.

Some people say that hard contact lenses will save you money in the end. They cost much more to buy than one pair of soft lenses but, considering that they hold their shape and do not tear, a Gas Permeable lens is most likely to hold up and be worn for many years. Their sturdiness is one more factor that they are called hard lenses.

On the negative side of things, lots of people discover Gas Permeable lenses are extremely uncomfortable. There is obviously a reason that they are called "hard lenses"! It could take the wearer a long time to get used to the feeling of these contacts. Once you do get used to them, people find that if they do not put on the lens everyday then their eyes, which took as long to change, come to be unadjusted and start hurting again!

If you do not wear you lenses all day, for most of the day, you might want to reconsider buying a pair. They truly call for dedication and commitment. No lazy Saturday's with these lenses- you need to wear them every day!

Though hard lenses last longer than soft lenses, the replacement cost of hard lenses is much higher. Since you shouldn't have to replace them that often, you could say it pays off and this is a non issue.

Speaking of a change in prescription, one of the reasons your optometrist may suggest you get hard lenses is if you have eyes that change numbers all the time. It is thought that GP lenses slow down the changes in your eyes and can prevent your eyes from getting worse.

There is a whole other option for contact lenses- the world of disposable lenses. Today, one can buy lenses and throw them out every day! This is the most hygienic option because it keeps gunk from building up on your lenses as you start with a new, factory sealed pair every day.

A huge advantage of daily lenses, or ones that you sleep with, is that you touch them a lot less. This prevents build up and dirt which may lead to an eye infection.

All in all, like with anything you are going to purchase, there are many factors to take into consideration. Speak to your eye doctor to find out what his opinion is.
