Anyone with a university-level diffusive operations education knows that pressure affects the solubility coefficient of a semi-permeable membrane. In high school terms, the contact can get squished and not allow the gas through as well. I'm not saying the argument is true and I'm not going to take the time to research and calculate (I had laser surgery last year so it's not of enough concern to me), but it is not totally baseless because of increased PO2's alone. Sure, but for the length of time a non-saturation dive takes, loss of permeability of the lens is irrelevant even if the lens were to become completely non-permeable, which wouldn't happen anyway. People used to wear non-permeable hard lenses all day without adverse effects before permeable lenses were developed. -Mike Rodriguez <mikey@ma*.co*> -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
