Best Digital Eye Chart Generators For Testing Visual Acuity

Eye charts are used to determine visual acuity and contain numerous rows of standard symbols in different sizes, known as optotypes. While eye charts have been used by eye specialists (ophthalmologists) since decades to determine vision related problems of patients, in recent years computer-based alternatives for eye charts have also become available. In fact, some eye charts are also available particularly for children and even resemble something as diverse as a video game. If you are looking to create a digital eye chart, here are a few applications that you can use to make one.

Eye Chart Maker

Eye Chart Maker is a web service which allows users to create their very own eye charts. This service not only allows making eye charts that are similar to the ones used by doctors but also allows users to add a custom message within the chart. Eye charts created with this service can even be shared with other users online. Simply head over to the Eye Chart Maker service, type a word or phrase in the textbox and a chart will be generated with your added word or phrase. This chart can then be saved as an image and added to anything from PowerPoint presentations to graphics and even e-cards (with a custom message).

  1. This is interesting information, but it should be stressed that testing visual acuity by using a chart that is not at the ISO or ANSI specifications, or at correct luminance, is NOT a substitute for an eye exam performed by a licensed Optometrist or Ophthalmologist. Reading letters from a chart is just one part of determining eye and vision health. Don’t take your vision lightly!
