Abstract

The error of refraction is a very common eye disorder. Untreated vision problems put a lot of burden on the global economy annually. One of the most important parameters in the correct treatment of visual defects is the correct assembly of the focal point of the glass. The study was carried out to reveal the decentration differences and the analysis of prism formation after glass assembly according to the prescriptions of 150 customers who came to an optical shop in Eskisehir on Saturdays, 2015-2016. A digital lensmeter was used for the measurement of glasses, and a digital and photographic pupilmeter was used to measure pupillary distances. Chi-square test was used in the frequency study, and differences in glass numbers were used the Marginal Homogeneity Test was used in the analysis of the accuracy of the data. Glass assemblies without decentration were achieved at a rate of 94.66% in distance glasses and 93.33 % in near glasses. When the errors made in applied physics are analyzed, the amount of decentration in the assembly of the glasses that are frequently used in daily life draws attention. In this case, it caused unwanted prism formation.
