Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Has had a self-reported visual exam in the last two years
* Is an adapted soft contact lens wearer
* Has a contact lens spherical prescription between +6.00 to - 9.00 (inclusive)
* Have no less than -0.75D of astigmatism and no more than -2.25 D in both eyes.
* Can achieve best corrected spectacle distance visual acuity of 20/25 (0.10 logMAR) or better in each eye.
* Can achieve a distance visual acuity of 20/30 (0.18 logMAR) or better in each eye with the study contact lenses.
* Has clear corneas and no active ocular disease
* Has read, understood and signed the information consent letter.
* Patient contact lens refraction should fit within the available parameters of the study lenses.
* Is willing to comply with the wear schedule (at least 5 days per week, \> 8 hours/day assuming there are no contraindications for doing so).

Exclusion Criteria
* Has a spectacle cylinder less than -0.75D or more than -2.50 D of cylinder in either eye.

* History of corneal ulcers or fungal infections
* Poor personal hygiene
* Has a known history of corneal hypoesthesia (reduced corneal sensitivity)
* Has aphakia, keratoconus or a highly irregular cornea.
* Has Presbyopia or has dependence on spectacles for near work over the contact lenses.
* Has undergone corneal refractive surgery.
