Occupational testing of near vision

The quality of near vision depends on distance visual acuity, accommodation capability and near vision correction, and cannot therefore be expressed in acuity values. Most near vision tests do not recognize this, and the lack in standardization should be mainly attributed to this fundamental shortcoming. A new test, the Priegel test, with a basically different conceptual basis is introduced. Its characteristics are discussed and a comparison with existing near vision tests is made. Consequences for legal testing are drawn.
