Oxygen tension under a permeable contact lens with and without tears.
Oxygen tensions were calculated under two different oxygen-permeable, flexible contact lenses (daily wear and extended wear) both with and without consideration of tear layers (but without tear exchange). Tear layers do not have significant effects on precorneal oxygen tension.
