[Technical aspects of measurement for optically sophisticated eyeglasses].

This paper deals with the question of how aspherical ophthalmic lenses can be measured outside the reference point given by the manufacturer in order to make a lens comparison or to test the shape faithfulness of the lens surface. Three procedures are presented with measuring examples - vertex power measurement with swiveled lens mount, probe scan in a three-coordinate measurement, and interferometer measurement using a non-ideal reference lens. The basic problem inherent in an application-related interpretation of the measuring data sets gained by these methods is shown.

[Aspherical single-strength eyeglasses with improved wearing comfort].

A new plastic single-vision lens series is presented with an aspherically designed front surface for the weak to medium-strength positive power range. With this lens the asphere is used to improve the non-optical properties and, at the same time, to maintain an image quality comparable to the high standard offered by regular spectacle lenses. The various factors which determine the optimization of so-called comfort in wear are discussed in detail.

A new screening method for detecting colour vision deficiencies.

Diagnostic colour vision examinations are generally administered with the anomaloscope. But this instrument requires a lot of time and experience for the tests as well as for the interpretation of the results. In practical use, it will be sufficient in most cases to know whether normal colour vision is present or not, and it is not necessary to use sophisticated devices. So it was considered desirable during the TCU conference on colour vision defects held in London in March 1973 [1] to have a testing method for practical use which is both accurate and time saving. At the time when this demand was brought up, a new colour vision test was being developed by Rodenstock [2]. It enables semi-skilled personnel to perform the test independently of ambient light condition in only 20-30 sec and to effect a classification of the type of colour vision at the same time [3].
