It’s not a widely known fact that contact lenses are not all the same. Some of them may be more suitable for your eyes compared to others. It depends on your preferences and your particular vision needs and problems. Your doctor may suggest the type of lenses you should wear but it is you who has to select the specific ones that best suit you.
Contact lenses can be classified into the materials they are made of: two basic categories of materials are: hard lens-which are kind of rigid, and soft lens. The rigid lenses are further classified into two more sub categories, which consist of: 1) Gas tight conventional rigid-these don’t allow gaseous free flow, 2) Gas permeable rigid-these allow natural gaseous flow through the material.
Rigid gas permeable (RGP) contacts are composed of semi-flexible plastic material that might initially take some time for the eye to adapt to, but your eyes will eventually get used to them. These lenses can provide sharper vision in many cases. They are also more durable and more expensive, as compared to the soft lenses. Extended wear lenses allow the user to wear them overnight and are also available in RGP form.
Almost all soft lenses are classified under Gas permeable and depend on water content (usually 80% water) and moisture content. These lenses are usually favored more because they are usually more comfortable to wear. There are also extended wear soft lenses that are for people who prefer to wear them over night.
Most people like disposable contact lenses since they can be thrown away after wearing them a while and then you simply get fresh new ones from almost any discount contact lenses supplier.
As in cases for astigmatism, Toric contact lens are available and they provide a slightly curved surface causing better vision for the patient. Toric lens will stay in place while moving around on your eye yet still allow for steady vision. There are many other lenses of this kind but Toric generally works the best in most cases.
Bifocal lenses are also available in both soft and RPG. They, just as the name suggests, have two areas in the lens, one for near vision and the other for far vision. They require a certain period of time for the human eye to adapt to them.
For those who just want to wear contact lenses for a different eye color or for the classy “cat-eye” look, they might want to get the special effect lens or the novelty contact lenses that are for non-prescription purposes.
Many chose to use colored contact lenses when they want their outfit to be completely color coordinated. You can also get colored contact lenses if you are not happy with the color of your eyes or if you just want a change in your looks since these colored contact lens can alter the natural color of your eyes. For a slightly different look, it is suggested that you get an enhancement tint. The lenses with enhancement tint have slightly darker color than you natural eye color. Although these lenses are transparent, the color is there to just give emphasis to the natural eye color.
Switching over to colored contacts is a lot of fun for many individuals. Even if you have a natural eye colored like blue, you can wear green contact lenses just to bring a difference to your facial appearance. And these days the cosmetic contact lenses are available at a very cheap price from any number of contact lenses online providers.
