Abstract
The cornea requires a minimum level of oxygenation; this may be prevented by a contact lens, and corneal swelling and other undesirable effects may result. By employing thin-film lubrication theory, this study derives analytical solutions for tear-film velocity components and pressure under a circular contact lens. Oxygen-tension contours are then obtained for various values of squeeze action and parallel motion of the lens.
摘要
角膜需要最低水平的氧合作用；而隐形眼镜可能会阻碍这种作用，进而可能导致角膜肿胀及其他不良影响。通过运用薄膜润滑理论，本研究得出了圆形隐形眼镜下泪膜速度分量和压力的解析解。随后针对镜片的挤压作用和平行运动的不同值，得出了氧分压等值线。
