Introduction
This Directions for use manual is a comprehensive guide designed to help you understand
the capabilities and operation of your Spot Vision Screener VS100. The information in this
manual includes all options available with the Spot Vision Screener. The applicability of
some sections of this manual depends on the configuration of your particular device.
Read this manual thoroughly before attempting to use the device.
The vision screener is a hand-held instrument with a video display on the rear of the unit
that provides subject visualization and alignment. Video display also provides user
interface functionality for data input and display. The vision screener provides visual and
audible cues to attract subject’s attention and gaze. The device provides a fast data collect
for easy evaluation of the most difficult pediatric subjects of limited compliance. Each
evaluation provides simultaneous binocular assessment of the subject’s refraction, pupil
size and gaze.
Intended use
The Spot Vision screener is intended to measure the refractive power of the eye by
measuring light reflexes from the retina. It also estimates pupil size, pupil distance and
eye gaze deviation. It is intended for use on subjects six months of age through adults.
Indications for use
The Spot Vision screener is indicated for use by healthcare professionals or under the
direction of a healthcare professional to screen or evaluate individuals for potential
refractive errors associated with poor vision.
Contraindications
The Spot Vision Screener has no known contraindications.
