[The standardization of near visual acuity].

The determination of close visual acuity is done accurately if the vision exam at a distance of 40 cm is standardized and if an exact estimation of the near visual acuity for professional activities of normal people and people with bad visual acuity can be made. The model of an optotype for near vision, Snellen metric type, using the Jaeger notation from 1 to 16 and also the standardized point system from 3 to 36, is presented. A professional selection of people with bad visual acuity after near visual exam is also presented.
