Eye Chart Pro generates randomized Snellen Charts and Tumbling E Charts for accurate visual exams. It is a very useful app especially for those who have already learned the default chart from medical offices.
This app works like an ophthalmic projector and has a clear interface with smooth shifts between the charts. Besides the letters randomization it also offers isolation of the letter lines, displaying them individually. The letters have a Sloan Sans Serif design and you can also adjust sizes.
The charts and letters randomization ensures a rough measurement of visual acuity. Eye Chart Pro features also metric functionality and various bells and whistles sound for a more attractive pointing of an item and a remote control, which can be downloaded separately.
