Vision is a very important sense that would be hard to live without. That is why if there is even the slightest problem with vision, means to correct the problem must be found. There are two kinds of equipment that have been invented for vision correction, that is, contact lenses and eyeglasses. People wear contact lenses when they do not want to wear eyeglasses. When in need of Contact Lenses Gulf Shore Al should be visited.
There is a new method devised which involves surgery. This type of surgery is referred to as LASIK surgery. This surgery is usually done by professional eye surgeons to give one the ability to see without the need for glasses or lens. For those who do not wish to have this surgery, contact lens is an option.
The material that a lens is made from should be one of the major factors to consider when buying the product. The level of vision correction and comfort of the product are usually highly dependent on the material used to make it. In general, lenses can be classified into five types today. The five types include soft, PRIMA, hybrid, silicone hydrogel, and gas permeable contact lenses. All of the five types have different merits and demerits.
The soft-gel lens is made from a gel-like plastic which holds water. The plastic used is referred to as a hydrogel. This lens is thin in size and flexible this makes it to adapt to the shape of the eye surface. Since its production in the 1970s, it has gained a lot of popularity because it is comfortable to wear.
A silicone hydrogel lens is simply an advancement of the soft lens. However, silicone hydrogel lens has more porosity, which allows more oxygen gas from the surrounding to reach the cornea of the eye. This kind of lens was introduced in the year 2002 and it has become the most popular product in the United States. Other countries are also adopting it at a very fast rate.
The abbreviations GP and RGP are usually used to refer to gas permeable lens. These products resemble PRIMA lenses closely and they are rigid as well. Although they are rigid, they still admit oxygen through them. The porosity of the product makes it comfortable and possible to fit them closer to the eye as opposed to other rigid lens products. Introduction of the product happened in 1978.
Unlike other contact lenses, hybrid lens is designed to give the wearer more comfort. The lens is designed to be rigid with a central area which is porous to gas. The material used to make the area around the porous is made of silicone hydrogel or a hydrogel material. They are not popular because fitting them in the eye is not easy and replacing them is very expensive.
Finally, PRIMA lens is a special kind of lens manufactured from rigid plastic materials that is also transparent. The abbreviation PMMA is used to refer to the plastic, which is called polymethyl methacrylate. Although the lens is not porous, which means that it cannot allow oxygen through, it has very good optics. They are hard for new wearers to adapt to them.
