Oxygen properties
Manufacturer-reported Dk/t 90 at −3.00 D. The cited specification table does not state units or a measurement method. Dk is not separately given in that table and is not derived from Dk/t. Water content shown is core water content, not surface water content. Dk and Dk/t are distinct properties; neither is calculated from the other.
Find a valid combination
Choose one or more parameters. All selected values must occur together in a single lens variant. This checks the documented parameter grid, not current stock.
The July 2026 U.S. grid lists 3,130 parameters. Axes depend on sphere band and cylinder; −2.25 and −2.75 cylinders use narrower axis sets. Plus powers start at +0.25; quarter steps stop at −6.00, with half steps to −10.00.
3130 combinations represented from the source grid. Individual values cannot be freely combined.

Each row is one combination represented from the source grid. “Not applicable” means this design does not use that parameter.
