There are many types of lenses available in the market. Each type has its advantages and disadvantages associated with them. But it is very necessary to choose the best types of contact lenses that fit your needs. As this is a matter of eyes so we can not take it casually. Instead, each and every detail associated with contact lenses have to be noted and taken good care of.

Here are some types of contact lenses listed with their associated usage and advantages.


  • Rigid Gas Permeable (RGP)

Gas permeable contact lenses are rigid contact lenses that are made up of durable plastic that transmits oxygen. These lenses also are called GP lenses. These lenses float on a layer of tears and cover about 75 percent of the cornea. RGP lenses provide better vision, durability, and deposit resistance. These lenses last longer than other types of lenses and are less expensive.



Certain advantages associated with them are-
  1. Excellent vision
  2. Short adaptation period
  3. Comfortable to wear
  4. Easy to put on and care for
  5. Relatively long life

  • Daily Wear Soft Lenses

Daily wear contacts are intended to be worn for an entire day and are designed to be comfortable for hours on end. Daily wear contacts can be reusable or disposable. They must be removed before sleeping.



Certain advantages associated with them are-
  1. Very short adaptation period
  2. More comfortable and more difficult to dislodge than RGP lenses
  3. Available in tints and bifocals
  4. Available in lenses that do not need to be cleaned
  5. Great for an active lifestyle
  • Extended Wear Contact Lens
Extended wear contacts can be comfortably worn both night and day. Initially extended wear contacts involved the lack of oxygen flow and the discomfort that can come from long-term wear. But modern technologies have made the adjustment with more breathable plastics and technology.

Certain advantages associated with them are-
  1. Can usually be worn for up to seven days without removal.
  2. Some lenses are FDA-approved for up to 30 days
