ACCURATE DETECTION
Six Vision Risk Factors
Backed by peer-reviewed clinical evidence, the Spot Vision Screener enables fast and objective detection of six amblyopic risk factors (myopia, hyperopia, astigmatism, anisometropia, strabismus and anisocoria) in children as young as six months old.

The Spot® Vision Screener is a handheld, portable device designed to help quickly and easily detect vision issues on patients as young as six months for the best chances of an early diagnosis. Get results in seconds. Automatically capture an image from a non-invasive, three-foot distance using the fixation target and sounds that help keep a child’s attention. A bright touchscreen displays instant results, indicating whether measurements are in range or a complete eye exam is recommended. Results are easy to interpret and share with parents and eye care specialists. The portable design is perfect for pediatric offices, schools and community vision screenings. Prepare for busy screening days by easily importing screening subjects to your queue via wireless connection* or USB drive.
