Because mistakes in refraction measurements correspond to fluctuations in eye＇s focus, it is possible to calculate theoretical limits for the best accuracy in measurements of eye＇s refraction （0.25-0.3 D）. Optical model for astigmatic human eye predicts possibility only 70% compensation of visual acuity by cylindrical glasses.

The article thoroughly investigates the unified theory (as Kintsch defines), construction-integration theory in text comprehension, which is mainly based upon the comparison with and analysis of the applications of schema theory from the perspective of language reading comprehension. The author tries to work out and illustrate this model as an alternative approach to the schema-oriented models previously used to solve reading comprehension problems in language teaching and leaning.展开更多
