- Has had a self-reported visual exam in the last two years.
- Is an adapted soft contact lens wearer.
- Is not a habitual wearer of either study lens.
- Has a contact lens spherical prescription between +5.00 to -9.00 (inclusive) best corrected visual acuity of 20/30 or better in either eye.
- Have contact lens prescription of no less than -0.75D of astigmatism and no more than -2.25D in both eyes.
- Can achieve best corrected spectacle distance visual acuity of 20/25 (0.10 logMAR) or better in each eye.
