    gas permeable

  • (of a contact lens) Allowing the diffusion of gases into and out of the cornea
  • (Gas permeability) is the permeability of an insulating layer for gaseous substances. The gas flow requires a difference of pressure and is characterized by the permeability coefficient (DIN 53380, DIN 535536, ISO 1399).
  • (Gas Permeability) Amount of air that can go through a lens.
  • (Gas Permeability) the ability of a gas or other volatile substance to penetrate a material. Materials that will allow significant passage of gases are said to be permeable, while materials that resist or stop the passage of gases are said to offer gas barrier properties.

Normally rigid contact lenses are pushed under the upper eyelid while blinking and in most cases they remain in this lifted-up position until the next blinking, if the eye is not moved to much. Otherwise they slip down slowly and were lifted up with the next blinking.
