  • Soft contacts – made of pliable hydrophilic or water loving plastics called hydrogels. They absorb water to keep the lenses soft and supple
  • Rigid gas permeable contacts – also called GP lenses are made of gas permeable material and are like hydrogels. These allow oxygen to pass through the lenses to the cornea. They do not contain much water but are porous.
  • Hybrid contact lenses -these are rigid GP central optical zone surrounded by a peripheral fitting zone mad of soft contact lens material.
