Critical-Line™ LED Quantum Device Kits

The Critical-Line™ LED Quantum Device Kits from Good-Lite are vision screening devices for children aged 3 through high school. The design streamlines the process, requiring only one person to conduct thorough screenings.  Variables such as illumination on the chart face and chart viewing angle are effectively eliminated, ensuring accurate and reliable results with every screening. Say goodbye to the hassle of adjusting lighting conditions or struggling with viewing angles.

• Device was developed in accordance with current recommended guidelines for critical line screening by age.
• Answer key printed on the remote button eliminates need to look at chart while screening.
