Design Notes
Stabilization
A patented dynamic stabilization design holds the toric axis.
Surface
AQUAGRIP technology gives the lens its dimensional stability.
Fitting
Sphere powers run -8.00 to +4.00, with cylinders of -0.75D, -1.25D, -1.75D and -2.25D and axes from 10 to 180 degrees in 10 degree steps.
Base curve
8.70.
Diameter
14.40 mm.
Handling tint
Light blue.
Replacement
Monthly wear.
Packaging
Standard pack size is 6 lenses.
Note
Orientation is described two ways, an arrow positional mark and a single line indication at 6 o'clock.
Initial Fitting Guide
Convert the spectacle Rx to minus-cylinder form, vertex-compensate both principal meridians to 0 mm, then add half the cylinder to the sphere. Clearlab's keratometry shortcut gives one stock design: for an average K of 39.50 to 41.50 and higher, 8.6 mm base curve / 14.2 mm diameter. Trial-fit and judge lens rotation off the single 6 o'clock line.
