OPTOMETRY MEASURING SCALE

摘要

The invention concerns an optometry measuring scale and method for determining a visual refraction value of an individual. According to the invention, the optometry measuring scale comprises a plurality of processed optotypes (2H) associated with a plurality of visual refraction corrections, wherein each processed optotype (2H) results from applying to a source optotype (2E) a determined image processing (2F) associated with a defined visual refraction correction, and an identification system (2G) for determining each defined visual refraction correction associated with each processed optotype (2H).
