Description
Inclusion Criteria:
- Male or Female
- Age 30 through 65 years at the time of consent
- Binocular vision
- Subject desires refraction for correction of visual acuity and vision can be corrected in each eye to 20/20 (LogMAR 0.0)
- Willing and able to give informed consent and follow all study procedures and requirements
- Ability to speak and understand the English language
Exclusion Criteria:
- Spherical correction > +8 or < -10
- Using anticholinergic medications (including first-generation antihistamines) or other medications known to affect visual acuity within the greater of 3 days or 5 half-lives prior to enrolling in this study
- Using an investigational drug or approved therapy for investigational use within the greater of 3 days or 5 half-lives prior to enrolling in this study
- Has initiated any new medication in the past 2 weeks that, in the best medical judgment of the investigator, would impact their participation in the study or ability to use the device
Eye disease, including but not limited to:
- Glaucoma (≥ 22 mmHg intraocular pressure)
- Cataracts (≥ 1+ nuclear sclerotic cataract, ≥ 1+ cortical, posterior subcapsular cataract [any grade using the Lens Opacities Classification System III])
- Macular degeneration (retinal pigmented epithelium mottling and/or any drusen within 500 μm of macula)
- Eye infection (corneal ulcer, corneal infiltrates, superficial punctate keratitis)
- Keratoconus
- Diabetic neuropathy/retinopathy (≥ mild nonproliferative diabetic retinopathy)
- Cytomegalovirus retinitis
- Color blindness (any color deficiency)
- Diabetic macular edema (evidence of fluid)

- Strabismus (exotropia, esotropia, and hypertropia)
- Abnormal astigmatism (mild to severe, > 5 diopters)
- Macular hole
- Eye surgery within the last 12 months (including Lasik or lens replacement)
- Subject does not have the physical dexterity to properly operate the device or the on the smartphone in the investigator's opinion.
