It is reported on 71 visually handicapped pupils. The visual acuity of 48 of these children could be tested with low-vision aids and the electronic television reading apparatus (Reinecker). With telescopic glasses (Zeiss, Keeler) 31 children had an average improvement of their visual acuity of two lines on a test board for near vision (Birkhäuser). With the reading apparatus 43 children showed an improvement of the visual acuity of 5 more lines. Only 3 to 21 pupils, who had been offered a regular use of the telescopic glasses, decided to have one. Finally our own experiences are compared with those of other authors.
