  • Title: [New special eyeglass lens for emmetropic presbyopes].
    Author: Barth R.
    Journal: Klin Monbl Augenheilkd; 1985 Jul; 187(1):73-5. PubMed ID: 4068577.
    Abstract:
    Emmetropic presbyopes are not used to wearing bifocal or progressive-power lenses all the time. Reading spectacles have the disadvantage that they have to be removed when the wearer wishes to look into the distance. Therefore, these people are turning increasingly to pulpit spectacles, which correct their vision for reading while leaving the long-range vision to which they are accustomed unchanged. However, conventional pulpit spectacles do not enable emmetropic presbyopes to see clearly at intermediate distances. This article deals with a type of pulpit spectacles which have been specially developed for emmetropic presbyopes. The glasses have an aspheric surface which provides for clear vision at reading distance as well as at all intermediate distances.
