Primary purpose: DIAGNOSTIC

Brief summary: Demonstrate that refraction measurements from the device agree with refraction measurements from a phoropter within clinically meaningful limits.

Detailed description: The primary purpose of this study is to attain scientific objective evidence to support the VisionCheck Indications for Use by demonstrating that refraction measurements from the device agree with refraction measurements from a phoropter within clinically meaningful limits. The Indications for Use are:

"The EyeQue VisionCheck automated subjective refraction system provides an estimate of sphere, cylinder, and axis measurements of the eye"

Furthermore, the purpose of this study is to attain scientific objective evidence regarding the precision of the VisionCheck device.

Eligibility criteria: Inclusion Criteria:

Each participant must meet the following criteria to be enrolled in this study:

1. Participant or legally authorized representative (LAR) is willing and able to give informed consent
2. Participant is willing and able to follow all study procedures and requirements
3. Participant is able to use a smartphone
4. Participant is interested in getting refraction correction measurement
5. Participant is able to speak, read and write English fluently

Exclusion Criteria:

Participants who meet any of the following criteria will be excluded from the study:

1. Spherical correction \>+8D or \<-10D (outside the range of the VisionCheck measurement)
2. Astigmatism correction of less than -5D (optometric notation, outside the range of the VisionCheck measurement)
3. Inability to see the red and green lines (may be overlapped to form a, partially, yellow line) through the VisionCheck device
4. Participant does not have the physical dexterity to properly operate the EyeQue VisionCheck device or the EyeQue app on the smartphone in the Investigator's opinion
5. Has initiated any new medication in the two weeks prior to enrolling in this study that, in the best medical judgment of the Investigator, would impact their participation in the study or ability to use the EyeQue VisionCheck device
6. Eye surgery within 12 months prior to enrolling in this study (including Lasik or lens replacement)
7. Using anticholinergic medications (including first-generation antihistamines) or other medications known to affect vision within the greater of three days or five half-lives prior to enrolling in this study
8. Using an investigational drug or approved therapy for investigational use within the greater of three days or five half-lives prior to enrolling in this study
9. Color deficiency (Ishihara pseudoisochromatic plates: Concise 14-plate edition: six or more errors on plates 1-11; the 24-plate edition: seven or more errors on plates 1-15; the 38-plate edition: nine or more errors on plates 1-21)

    5. Diabetic neuropathy/retinopathy
    6. Cytomegalovirus retinitis
    7. Diabetic macular edema (evidence of fluid)
    8. Retinitis pigmentosa
    9. Amblyopia (best corrected visual acuity \[BCVA\] ≥ 20/30)
    10. Chronic or acute uveitis (cells and/or flare in the anterior chamber)
    11. Strabismus (manifest/latent, exotropia, esotropia, hypertropia, exophoria, and esophoria)
    12. Abnormal astigmatism (mild to severe, \> 4D)
    13. Binocular vision anomalies
    14. Chronic dry eye
    15. Monovision

Primary outcomes:
measure: Assess agreement between the VisionCheck refraction measurement and a phoropter (standard of care) refraction measurement.
timeFrame: 3 months
measure: Assess total variability and variance components for between- replicates (repeatability) and between-device/operator while adjusting for between-participant and between-site variability.
timeFrame: 3 months
Secondary outcomes:
measure: Assess improvement in visual acuity brought forth by the VisionCheck refraction measurement.
