About
Demonstrate that refraction measurements from the device agree with refraction measurements from a phoropter within clinically meaningful limits.
Full 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.

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

Astigmatism correction of less than -5D (optometric notation, outside the range of the VisionCheck measurement)
Inability to see the red and green lines (may be overlapped to form a, partially, yellow line) through the VisionCheck device
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
