ISO/TR 19498:2015 specifies a method of correlation between a given set of optotypes and the standard optotype (Landolt ring) formed and presented as specified in ISO 8596. All test methods are type tests and suitable equivalent test methods may be substituted.
Abstract
Overview
ISO/TR 19498:2015 is an international technical report published by the International Organization for Standardization (ISO) under the scope of ophthalmic optics and instruments. This report specifies a standardized method for correlating a given set of optotypes with the established standard optotype-the Landolt ring-as defined in . The method ensures consistent visual acuity testing by comparing various optotype sets to the Landolt ring, which serves as the reference.
