MultiBit is a new type of vision test that was specifically devised for participants in the MONARCH scientific study and requires special registration.
The MultiBit flashes sets of test digits that are built up by varying numbers of pixels. The test task is to spell out what digits were shown. When the test is completed, the recorded answers are played back to allow self-scoring of results. The results are automatically transmitted to the MONARCH study.
The app is developed by experts within the field of ophthalmology.
