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.
