Eye-charts

Traditional eye-charts, letterpress printed with a traditional 19th century iron handpress on heavy 3mm thick carton panels.

The type used in these eye-charts was reconstructed (in wood using CNC-technology) as per the original eye-chart type, designed back in 1862 by the ophthalmologist Dr. Snellen who developed the original chart, using alphanumeric capitals in a 5×5 grid.
