By Michael Young


Life would be very hard without the ability to see. That is why there are many solutions and treatment options geared towards correction of even the slightest vision problems. Contact lenses and eyeglasses are the two major devices that can be worn to correct vision. Contact lenses are worn in particular by people who do not wish to wear eyeglasses. When one needs Contact Lenses Gulf Shore Al offers the perfect location to visit.

Surgery has also come up as an option for vision correction. The surgery used to correct vision is called LASIK surgery. One may be able to regain full vision without any defects after the surgery is complete. High trained eye surgeons are responsible for conducting the procedure. One can always wear contact lens if they do not prefer surgery.

When choosing lenses, it is important to consider the material they are made from. The material the product is made from usually determines if it is capable of correcting the problem that the wearer has. Basically, there are five types of lenses on the market today. These are soft, silicone hydrogel, gas permeable, PRIMA, and hybrid contact lenses. All the five products are suitable for people with different eye problems.

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 an advanced form of soft lens. The main difference is that the former has more porosity, which admits a higher amount of oxygen to the cornea. Introduction of this lens to the mainstream occurred in 2002 and they have continued to become more popular. They are the most popular lens in the US, and many other countries are adopting them fast.

Gas permeable lens is also known by the abbreviations RGP or simply GP lens. These products are rigid and have a close resemblance to PRIMA lenses. However, despite being rigid, they are porous and allow oxygen to pass through. The porosity of these products allows them to be fit closer to the eye compared to other rigid lenses. They were introduced in the year 1978.

Hybrid contact lens puts more focus on comfort of the wearer. The lens is made of two zones, the inner central zone and the outer zone. The inner zone is made using a rigid material that is permeable to gas. On the other hand, the outer zone is made using silicone hydrogel material. These products cost more to replace and they also present difficulties fitting in the eye, which makes many people not to prefer them.

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.
