Image magnification is a well known means for print enhancement. However, a too large magnification hampers reading because of the decreased field of view. For certain patients with maculopathies, it has recently been reported that by using individualized compensation filters, less magnification is needed and higher reading rates are achieved. In this paper the possibilities of print enhancement for eccentric vision are explored further by using subjective estimates of image quality. The obtained results suggest that for two-tone text, image enhancement through spatial filtering, only makes sense in situations where the available contrast range is not entirely used.
