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.
