Inclusion criteria

  • The subject must read, understand, and sign the STATEMENT OF INFORMED CONSENT and receive a fully executed copy of the form.
  • The subject must appear able and willing to adhere to the instructions set forth in this clinical protocol.
  • The subject must be between 18 and 40 years of age.
  • The subject's vertex corrected spherical equivalent distance refraction must be in the range of -0.50 Diopters (D) to -8.00 D in each eye.
  • The subject's refractive cylinder must be no more than -1.00 D cylindrical correction in each eye after vertexing to the corneal plane.
  • The subject must have best corrected visual acuity of 0.20 or better in each eye.
  • The subject must be a current wearer of daily, spherical, soft contact lenses (no bifocal or multifocal contact lenses, no extended wear or monovision) for at least 5 days/week and at least 8 hours/day during the month prior to enrollment.
  • The subject must be using digital devices (any combination of computers, tablets, smart phones etc.) for at least 8 hours over the course of a typical day.
  • The subject should own a wearable pair of spectacles and wear them the day of the baseline visit.
  • The subject must have normal eyes with no evidence of abnormality or disease that in the opinion of the investigator would contraindicate contact lens wear.
  • The subject must meet normal eligibility conditions of binocular vision tests.
  • The subject may not have any double vision at near with their habitual contact lens correction.

Exclusion criteria

  • 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 (at the investigator's discretion).
  • Any systemic disease, autoimmune disease, or use of medication, which may interfere with contact lens wear (at the investigator's discretion).
  • Use of any medication that causes side effects similar to side effects experienced when using digital devices, such as a subject reporting headaches associated with birth control pills (at the investigator's discretion).
  • Any infectious disease (e.g., hepatitis, tuberculosis) or a contagious immunosuppressive disease.
  • Any active ocular infection.
  • Entropion, ectropion, extrusions, chalazia, recurrent styes, glaucoma, history of recurrent corneal erosions, aphakia, or moderate or above corneal distortion.
  • Any previous, or planned, ocular or interocular surgery (e.g., radial keratotomy, photorefractive keratectomy (PRK), laser-assisted in situ keratomileusis (LASIK), etc.).
  • Clinically significant (grade 3 or 4) corneal edema, corneal vascularization, corneal staining, or any other abnormalities of the cornea which would contraindicate contact lens wear.
  • Clinically significant (grade 3 or 4) tarsal abnormalities or bulbar injection which might interfere with contact lens wear.
  • Any known hypersensitivity or allergic reaction to the study products.
  • Participation in any contact lens or lens care product clinical trial within 7 days prior to study enrollment.
  • History of binocular vision abnormality or strabismus.
  • Employee of investigational clinic (e.g., Investigator, Coordinator, Technician).

200 participants in 2 patient groups

Group 1 (TEST / CONTROL wear sequence)
Active Comparator group
Description:
Subjects randomly assigned to the TEST Contact Lens or the CONTROL Contact Lens in the TEST / CONTROL wearing sequence will wear each of the study lenses for 4 weeks according to the manufacturer's guidelines. Subjects will be dispensed the other (second) lens type at the second dispense visit.
Treatment:
Device: TEST Contact Lens
Device: CONTROL Contact Lens
Group 2 (CONTROL / TEST wear sequence)
Active Comparator group
Description:
Subjects randomly assigned to the TEST Contact Lens or the CONTROL Contact Lens in the CONTROL / TEST wearing sequence will wear each of the study lenses for 4 weeks according to the manufacturer's guidelines. Subjects will be dispensed the other (second) lens type at the second dispense visit.
Treatment:
Device: TEST Contact Lens
Device: CONTROL Contact Lens
