Visual Acuity Tests

A visual acuity (VA) test measures how well you see the details of a letter or symbol from a specific distance. Distance VA is typically measured at 6m, but 3m charts are also available. Near VA is measured at 40 cm or at the person’s working distance. VA is measured with print or digital charts (desk top monitor, tablets or smartphone apps)

Chart designs vary e.g. Snellen and logMAR, and various levels of contrast and simplified charts for vision screening are also available.
Charts are made up of various optotypes including letters, or symbols and tumbling Es for pre-literate people, and passages of text to assess near vision. The size of the optotypes typically range from 6/5 to 3/60, and low vision charts have larger optotypes.
