摘要：
Disclosed is 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 associated with a plurality of visual refraction corrections, wherein each processed optotype results from applying to a source optotype a determined image processing associated with a defined visual refraction correction, and an identification system for determining each defined visual refraction correction associated with each processed optotype.
