- The subject must appear able and willing to adhere to the instructions set forth in this clinical protocol.
- The subject must be 18 and less than 40 years of age.
- The subject's corrected spherical equivalent distance refraction must be in the range of -1.00 to -5.00D in each eye with visual acuity of 20/25 provided study lenses in each eye.
- The subject must have less than -1.00 D of cylindrical refraction.

- Currently pregnant or lactating (subjects who become pregnant during the study will be discontinued)
- Any ocular or systemic allergies or diseases that may interfere with contact lens wear.
- Any systemic disease, autoimmune disease, or use of medication, which may interfere with contact lens wear.
- Entropion, ectropion, extrusions, chalazia, recurrent styes, glaucoma, history of recurrent corneal erosions, or aphakia.
- Any previous, or planned ocular or interocular surgery (e.g. radial keratotomy, PRK, LASIK, etc.).
- Any grade 3 or greater slit lamp findings (e.g. edema, corneal neovascularization, corneal staining, tarsal abnormalities, conjunctival injection) on the FDA classification scale, any previous history or signs of a contact lens-related corneal inflammatory event (e.g. past peripheral ulcer, or round peripheral scar), or any other ocular abnormality that may contraindicate contact lens wear.
- Any ocular infections
- Any corneal distortion resulting from previous hard or rigid gas permeable contact lens wear.
- Participation in any contact lens or lens care product clinical trial within 7 days prior to study enrollment

- Primary Outcome Measures
Name Time Method Subjective Overall Comfort 11 days Post fit Subjective Overall Comfort was evaluated using the Contact Lens User Experience Comfort scores (CLUE). CLUE is a validated patient-reported outcomes (PRO) questionnaire to assess patient-experience attributes of soft contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Derived CLUE scores using Item Response Theory (IRT) follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response.
Subjective Overall Quality of Vision 11 days post fit Subjective Overall quality of Vision was evaluated using the Contact Lens User Experience Comfort scores (CLUE). CLUE is a validated patient-reported outcomes (PRO) questionnaire to assess patient-experience attributes of soft contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65.
