Probierbrillenglas Hit einer !Passung aus Kunststoff, beispielsweise aus PolystyrolTrial lens hit one! Fit made of plastic, for example made of polystyrene
Die Erfindung betrifft ein Probierbrillenglas mit einer Passung aus Kunststoff, beispielsweise aus Polystyrol« The invention relates to a trial lens with a fit made of plastic, for example made of polystyrene «
Probierbrillengläser mit einer Passung aus Kunststoff sind bekannt· Die verschiedenen Arten "von Kunststoffen sind jedoch nicht in gleicher Tieise für Passungen Ton Probierbrillengläsern geeignet» Eine ganze Eeihe von Kunststoffen besitzt zwar die geforderte Eigenschaft eines genügenden Widerstandes gegen eine zu rasche Abnutzung. Bs ergeben sich jedoch wegen, ihrer Härte und Sprödigkeit Schwierigkeiten bei ihrer Verarbeitung, da bei des Passen, insbesondere von astigmatischen Gläsemj häufig Brüche und Ausschuß auftreten« Auch sind nicht alle diese Kunststoffe tropenfest. Die Verwendung von elastischen Kunststoffen, die sich leichter verarbeiten lassen und die auch tropenfest sind, zeigte wieder den Nachteil einer unzulässigen Abnutzung, insbesondere der Passungsränder, bei stärkerer Beanspruchung.Trial glasses with a fit made of plastic are known · The different types of "plastics are not equally suitable for fits clay trial glasses" A whole series of plastics has the required property of sufficient resistance to too rapid wear Difficulties in processing because of their hardness and brittleness, since cracks and rejects often occur when fitting, especially astigmatic glasses. "Also, not all of these plastics are tropicalized. The use of elastic plastics, which are easier to process and which are also tropicalized , again showed the disadvantage of impermissible wear, especially of the fit margins, when subjected to heavy loads.
