Contact lenses are those thin optical discs that are placed in front of the eye ball so as to correct eye defects or eye sight problems. They are the simplified version of ordinary spectacles and you might not even see them in someone’s eyes if you’ve never heard of them. Generally contact lenses are a good development that has revolutionized the way people deal with eye problems.
There are so many different types of contact lenses available. But the two main sub-categories include soft lenses and rigid gas permeable lenses. The first class of lenses is soft and made of a much more refined optical disc material. These qualities inevitably make them more comfortable but with a smaller lifespan of just a year of usage until they’re disposed of.
On the other hand the rigid gas permeable (RGP) are harder and contain very little water as compared to the soft lenses. The two advantages that these have is that they do not accumulate dirt and they seem to be more powerful by refining image more accurately than soft contacts
Like I mentioned earlier, contacts must be selected on the basis of the specific eye problems that one is having. When you look at astigmatism, a condition where you’re unable to see images both far and distant, you soon realize that it is Toric lenses that are specifically prescribed. You can’t just visit a store and ask for a pair of contacts without some sort of prescription.
Another type of lens chosen with a particular predicament in mind are the Proclear lens. Proclear contacts help to treat and prevent dry eyes. Dry eyes is the unfortunate circumstance when the eye sockets contain very little water because the contacts in use have a very low water retention capacity of its own.
Proclear lenses work in a very unique way by combining natural human cell attributes with lens technology. Proclear lenses are capable of retaining their own moisture without resorting to tear moisture in the eyes. Subsequently these attributes increase the durability of lenses and at the same time reduce further damage to the eyes.
Other types of lenses are the disposable contacts and the extended wear lenses. With the disposable lenses you are at liberty to throw them away after a few days of use. They are generally more comfortable; healthier and more user friendly as you can apply and remove them yourself. On the other hand the extended wear contacts can be worn continuously for 30 days and are harder.
Generally it is advisable to visit an eye specialist if you have problems with eye sight. This is because without a doctor’s diagnosis you might wear the wrong contact lenses and worsen your eye problems.
