By Michael Young


Among the five senses, the sense of sight is very important.it can be hard to live without this sense thus it is important to correct any problem related to sight no matter how small it may be. The main equipment devised for correction of vision include glasses and contact lenses. One may opt to wear a contact lens if they do not wish to wear glasses. When in search of Contact Lenses Gulf Shore Al should be given priority.

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 production of soft lens is done using water-containing, gel-like plastic. This material is called hydrogel. The lens can conform to the surface of the eye well because it is thin and flexible. Introduction of the lens first occurred in the 1970s. Its level of comfort made it to be adopted by many people.

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.

Gas permeable lens can also be abbreviated as an RGP or GP lens. They resemble the PRIMA lenses and they are stiff. Despite their stiffness these products are permeable allowing oxygen to pass. These products were first produced in 1978 and they are popular than other stiff lenses because they can be fit close to the eye.

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.

The PRIMA lens is made from a hard transparent plastic material. This plastic material is known as a polymethyl methacrylate commonly shortened to PMMA. These lenses have very good optics but it can take a person several weeks to adapt to wearing them. This is because they are not permeable which means oxygen does not get to the eye thus they are not easy to get used to.
