Summary
The principal hypothesis is to be tested in this work is that vision stability (the primary outcome measure) with a spherical contact lens correction vs. a toric contact lens correction will be the same.
Detailed description
This will be a randomised, subject-masked, crossover, bilateral non-dispensing study, controlled by cross-comparison. Thirty subjects will use each lens type at a single visit in random sequence.
