Laminated in Perspex, for doctor or optometrist doing Domi work. Size 12 x 30cm. If the patient reads only the top letter (marked 60), their VA is recorded as 6/60 (or 3/30) providing the test was done at 3m viewing distance from the chart.The test should not be performed at less than 3m. If the chart was positioned on the wall immediately behind the patient and they observe the chart looking through a mirror that is 1.5m away, the viewing distance is 3m. If they only read the same letter but from 6m, their VA would be recorded as 6/30 (or 3/15). Hole at the top for hook, string drawing pin or nail. Printed at 90% contrast. A subset of letters with bilateral symmetry has been used to permit use looking through a mirror if necessary.
