Abstract: A device for vision testing comprises a viewing position (6) and an image surface (5). The distance between the viewing position (6) and the image surface (5) is enclosed. The relation between the resolution of the image surface and the distance between the viewing position (6) and the image surface (5) is such that the angle of a point on the image surface (5) is less than or equal to 1 minute of arc seen from the viewing position (6).
