Inclusion and exclusion criteria
Inclusion Criteria:
Potential subjects must satisfy of all the following criteria to be enrolled in the study.
Read, understand, and sign the STATEMENT OF INFORMED CONSENT and receive a fully executed copy of the form.
Appear able and willing to adhere to the instructions set forth in this clinical protocol.
Be between 18 and 39 (inclusive) years of age at the time of screening.
By self-report, habitually wear soft contact lenses (sphere or toric) in both eyes in a daily reusable or daily disposable wear modality (i.e. not extended wear modality). Habitual wear is defined as a minimum of 6 hours of wear per day, for a minimum of 2 days per week during the past 4 weeks.
Possess a wearable pair of spectacles that provide correction for distance vision.
In both eyes, have magnitude of the cylinder component of their vertex-corrected distance refraction greater than or equal to 0.625 DC and less than 1.625 DC.
In both eyes, have the mean sphere of their vertex-corrected distance refraction minus half of the indicated contact lens label cylinder power be between -0.875 to -4.625 DS (inclusive).
For each eye, have the cylinder axis of their distance refraction between 165° and 15° (i.e., 180±15°, inclusive) or between 75° and 105° (i.e., 90±15°, inclusive).
For both eyes, have the sphere power of their habitual spectacles within ±0.50 Diopters Sphere (DS) (inclusive) of the sphere power of their current subjective refraction.
For both eyes, have the cylinder power of their habitual spectacles within ±0.50 Diopters Cylinder (DC) (inclusive) of the cylinder power of their current subjective refraction.
For both eyes, have the cylinder axis of their habitual spectacles within ±20° (inclusive) of the cylinder axis of their current subjective refraction.
Achieve monocular VA of 20/30 or better with their habitual spectacles in both eyes.
