Gas permeable (GP) contact lenses

0 24 January 2015

Two Main Types of Contact Lenses:

Contact lenses are tiny discs of plastic placed on the surface of the eye, as a substitute for wearing glasses. Contact lenses are made of different types of plastics, but they fall into two main categories:

  • Soft contact lenses are gel-like and conform to the shape of your eye. They are very comfortable and are hardly noticeable once the lenses are placed on the eye. The replacement schedule ranges from daily to monthly disposable, and some are designed for extended wear overnight.
  • Gas permeable (GP) contact lenses are more rigid and smaller in diameter. Compared to soft lenses, GP lenses are more durable, allow more oxygen to enter your eyes, and can correct certain vision problems. However, they may be less comfortable initially and take a longer time to get used to.

 

Advantages of Contact Lenses:

  • They move with your eye, allowing a natural field of vision.
  • There are no frames or reflections to block your view.
  • They don’t fog up.
  • They do not get in the way of your activities.
  • You can wear sunglasses over them.
