    Abstract: The inventive method for recording data on an optical lens (2) consists in recording a data-containing source image, in generating the hologram (3) of the image source and in recording said hologram on the lens surface portion ranging from 0.5 mm to 15 mm. The data can be readout by illuminating said lens by means of a light beam (101) in the hologram area. A read-out image (105, 106) which reproduces the source image and on which data is readable is formed at a distance from the lens. Said lens can be embodied, in particular in the form of an ophthalmic lens.
