Intervention / Treatment
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.
