IFIrving Fatt

Key Points

  • The research aims to understand how blinking affects oxygen supply to the cornea when covered by a contact lens.
  • Analyzed the dimensions of the tear reservoir under the lens.
  • Evaluated blinking rates and their impact on oxygen delivery.
  • Assessed the efficiency of tear exchange during a blink.
  • Blinking enhances oxygen availability to the cornea.
  • Dimensions of the tear reservoir significantly affect oxygen levels.
  • Faster blinking rates improve tear replacement, boosting oxygen supply.

Abstract

ABSTRACT The blinking process supplies oxygen, dissolved in the tears, to the cornea covered by a contact lens. The dimensions of the reservoir, the rate of blinking, and the efficiency of tear replacement under the lens by a blink are factors that govern the availability of oxygen to the cornea.
