GP (oxygen permeable) contact lenses offer many benefits including crisp vision, high oxygen permeability, myopia control, durability and overall value.
Before you make the decision to wear soft contact lenses, please read this guide to GP contact lenses from the Contact Lens Manufacturers Association. It has been prepared to help you choose the contact lenses that are right for you.
Even if you already wear contact lenses, you may not realize how many different kinds of contacts there are, or how new materials and designs can improve your vision and eye health.
For example, GP bifocal contact lenses are helping people over 40 to avoid bifocal eyeglasses and reading glasses. And many wearers consider GPs an excellent LASIK alternative.
Contact Lens Designs
Many lens designs come in colors that can enhance or change your natural eye color. Special-effect contact lenses are also available for novelty use and are used extensively in theatrical and filmed productions. Prosthetic lenses are colored contact lenses that can cosmetically mask eye disfigurement. Many contact lenses come with an embedded UV inhibitor as well.
About Contact Lenses
Modern contact lenses fall into two categories: soft lenses that are made from water-containing plastics, and GP or "oxygen permeable" rigid contact lenses.
Contact lenses may also be classified by wearing schedule. Daily wear contacts must be removed, cleaned and stored each night, while extended wear contact lenses are made from materials which are safe for sleep. You may also have heard of "continuous wear" contact lenses, a type of extended wear lens that can be worn for up to 30 days.
Various contact lens designs are available for different vision problems. Spherical contact lenses correct nearsightedness or farsightedness and are indicated by a minus or plus in your prescription, respectively. Bifocal contact lenses are similar to multifocal eyeglasses in that they use different optical zones to correct presbyopia (the decreased ability see at both near and far distances). Toric contact lenses correct astigmatism, which can accompany either nearsightedness or farsightedness.
All of the contact lenses mentioned above can be custom fabricated for unusual prescriptions, and many other contact lens designs are available as well, including designs for conditions like keratoconus.
