The Welch Allyn Spot Vision Screener is a handheld, portable device designed to help users quickly and easily detect vision issues on patients from 6 months of age through adult. Spot screens both eyes at once from a nonthreatening 3-foot distance. The touch-screen display allows for one-touch activation, simple management of patient data entry, and easy configuration for both vision screening and autorefraction applications.
