Time course of corneal oxygen uptake during contact lens wear [PDF]

, 1988
We used a polarographic oxygen sensor to measure corneal oxygen uptake rates of 16 subjects during daily wear of soft contact lenses. The subjects reported for examinations on nine occasions over a 30-week lens wearing period. Corneal oxygen uptake rates

Computation of Analytical Zoom Locus Using Padé Approximation

Mathematics, 2020
When the number of lens groups is large, the zoom locus becomes complicated and thus cannot be determined by analytical means. By the conventional calculation method, it is possible to calculate the zoom locus only when a specific lens group is fixed or ...
