The measurement of visual acuity are ordinarily carried out by Landort's ring or Snellen type with Latin letters. These measurements fail to find out a large amount of information relating to visual function. On the other hand, the measurement by grating is able to detect those information, because it is well known that contrast sensitivity function provide most detailed information about the visual function. Amblyopic persons have some difficulties caused by their visual dysfunction specific to each person. In order to find these function, recently, it has frequently used grating for the mesurement of visual acuity. Another important aspect of visual acuity is that it is a measure of the finest detail that an individual can discriminate in the visual environment and act with the adaptable behaviour in it. The behavioural assessment is a kind of method about the mesurement of visual acuity. Although a preferential looking method is one of this style, visual acuity dose not only take a role as a mere procedure of diagnosis on the amblyopia, but it should more intensely take a consideration in relation of visual acuity for behavioural assessment.
