You can now switch your old Snellen vision test charts to LogMAR without replacing your illuminated or rotating test type. 
We have developed a range of LogMAR charts with optional LED Light Boxes to meet the international Gold Standard for visual acuity testing on standard size acrylic charts.

These lightweight LED illuminated boxes hold a single vision testing acrylic panel and have a spotlight below the panel. A manual side switch will select which section is illuminated. The box is white and can be wall-hung, or stood on its feet plus integral stability bar.
