Caption

Eyesight test chart. Lightbox with rows of letters of varying size. The letters are mirror images, designed to be read in a mirror. This allows a mirror to be placed at the required distance, rather than moving the lightbox itself. The patient is asked to read the letters from a particular row, allowing an optician or ophthalmologist to assess the patient's eyesight. Photographed at the Princess Alexandra Eye Pavilion, Edinburgh, Scotland.
