title: [A new system of testing visual performance based on the cylindrical lens screen].
abstract: Using a special microoptical screen as a test-picture coating, a method for testing binocular function was developed. It offers the advantage of providing a separate visual impression to each eye from a diagnostic picture without using any device in front of the eyes. The person tested is unaware of this procedure, of which the diagnostic plate gives no hint. In addition to a description of its numerous uses and diagnostic possibilities, fusion pictures suitable for screening tests are described: Each eye is offered a separate impression with a completely different content. If fusion occurs correctly, a third motif with an entirely new meaning emerges. Several years of experience with this effective system (naked-eye tests) resulted in aids which are listed in the final section of the paper: exercise aids used for preparing the persons tested (especially infants) in the waiting room, recognition aids for the examination, and a partially kinetic picture for rapid, simple and very convincing representation of adjusting movements and of the squint position in cases of concomitant squint.
