A person is eligible for inclusion in the study if he/she:
- Is between 18 and 35 years of age (inclusive)
- Has read and signed the informed consent letter
- Is willing and anticipated to follow instructions and maintain the appointment schedule
- Habitually wears soft spherical contact lenses with a power between -1.00D to -6.00D (inclusive) for a minimum 5 days per week, 10 hours per day and anticipates no difficulty wearing contact lenses for 7 days per week, 10 hours per day.
- Habitually wears or is able to be adequately refit into MyDay Sphere lenses
- Demonstrates an acceptable fit with the study lenses
- Is correctable to a distance visual acuity of 0.20 logMAR (approximately 20/30) or better (in each eye) with the study contact lenses
- Uses digital devices, (e.g. computer, tablet, smart phone, iPad), for more than 4 hours a day, 5 days a week.
- Manifest cylindrical spectacle refraction does not exceed -0.75DC in either eye
- Has clear corneas and no active ocular disease
- Has a contact lens refraction that fits within the available parameters of the study lenses.
Exclusion Criteria:
A person will be excluded from the study if he/she:
- Is participating in any concurrent clinical research study
- Has a history of not achieving comfortable CL wear (5 days per week; > 8 hours/day)
- Has a systemic condition that, in the opinion of the investigator, may affect the study measures
- Is using any systemic or topical medications that in the opinion of the investigator may affect the study measures.
Presents with slit lamp findings or clinically significant anterior segment abnormalities that would contraindicate contact lens wear such as:
- Pathological dry eye or associated findings
- Significant pterygium, pinguecula, or corneal scars within the visual axis
- Neovascularization > 0.75 mm in from of the limbus
- Giant papillary conjunctivitis (GCP) worse than grade 1
- Anterior uveitis or iritis (or history in past year)
- Seborrheic eczema of eyelid region, Seborrheic conjunctivitis
- History of corneal ulcers or fungal infections
- Poor personal hygiene
- Has a known history of corneal hypoesthesia (reduced corneal sensitivity)
- Has a known sensitivity to the diagnostic pharmaceuticals to be used in the study
- Has aphakia, keratoconus or a highly irregular cornea.
- Has presbyopia or has dependence on spectacles for near work over the contact lenses.
- Has undergone refractive surgery.
- Is pregnant, lactating or planning a pregnancy (by verbal communication) at the time of enrollment
