摘要 |
A vision-testing apparatus includes a concave mirror and at least one test object (2) which can be changed in position and is arranged between the concave mirror (1) and its focal point (f) in a first optic path (W1). In order to be able to carry out different vision tests with an apparatus which is simple in design and compact in manufacture, it is provided that the eye (7) of a person being tested is arranged at a focal point (F) of the concave mirror (1) and that between the concave mirror (1) and the test object (2) there is arranged a first partially translucent dividing mirror (3) to form a second optic path (W2) from the concave mirror (1) to the eye (7) of the person being tested.
