DATA REGISTRATION PROCESS ON A LENS, AND LENS UNDERSTANDING REGISTERED DATA

摘要

data entry process on a lens, and lens comprising inscribed data. The present invention relates to a data entry process on an optical lens (2) comprising a record of a source image containing the data. A hologram (3) of the source image is then generated, then inscribed on the lens, occupying a surface part of between 0.5 mm2 and 15 mm2. the data may be used by illuminating the lens by at least one light beam (101) in place of the hologram. a reading image (105, 106) reproducing the source image is thus formed at a distance from the lens at which the data is readable. The lens may in particular be an ophthalmic lens.
