Celego Near Vision Test

Celego is a new, innovative, self-test for rapid self-assessment and monitoring of vision at a reading distance. Cultural and learning problems associated with traditional printed tests are avoided by presenting ever-new combinations of letters and digits. Using voice recording and playback the user self-scores results: no outside supervision is needed. The test depends on the fact that the time needed to read a text depends on its font size. Celego measures the smallest size that allows accurate reading within a fixed time. Test results are stored internally. Once a baseline has been set, repetition allows monitoring of change over time.
