Correcting Vision Problems
Contact lenses are popular because they can provide a higher level of vision than glasses. However, not all people want to wear glasses every day. If you’ve decided on contacts as your option for improving your vision, then there are a few things you need to know about these amazing lenses. There are generally three types of contact lenses – gas permeable, soft, and rigid gas permeable. Each type has its own pros and cons, but when it comes to choosing the right one for you, it’s important to understand the differences between them and make an informed decision.
Gas permeable lenses (RGP)
has more durability and resistance to deposit build-up, and as a result, they tend to offer a sharper, clearer vision. They’re also easier to clean, although some people with astigmatism may experience problems with the material coming out of the eye when it gets wet. They’re cheaper over the long run because they last much longer than soft lenses, but they aren’t as comfortable as rigid gas permeable lenses. Most people who wear RGP feel that the discomfort level is a lot less than some of the other types.
are made to fit into your eye much more comfortably. Because they are typically made from silicone, soft extended-wear disposable lenses are extremely hygienic and are recommended for those with dry eyes. They don’t stick and cause residue, which can be uncomfortable, in the eyes. When you first put on your contacts, you’ll likely notice that your eyes feel a little sore. This is from the contacts sticking to the front of your eyes for the first few days.
There are four different types
of Vision Correction Contact Lenses currently available on the market. They include topics, spherical, and prisms can. The toric lenses are the most common, as they correct both myopia and hyperopia.
Spherical Contact Lenses
require one day of installation for each set of contacts that you use. To use these lenses, you’ll remove the protective lens from your eye and place them in a storage case. Then you wear the special lenses one day at a time. However, there are a few disadvantages to spherical lenses: if you have astigmatism, you’ll need to take them in for cleaning twice a year.
One of the newest varieties of Vision Correction Contact Lenses
is called bifocal. They correct both myopia and hyperopia, by using two separate powers in each eye. Because bifocals are new technology, they come in more styles and designs than any other type of lens. However, the biggest disadvantage to bifocals is that they cost more than spherical. If you suffer from chronic astigmatism, you should research bifocal contacts as your treatment of choice.
