Abstract: The measyuraments of eye refraction, obtained with the aid of two conventional techniques, such as vision test charts and Badal’s optometer, are known to agree with the data obtained with the recent laser refractors, the accuracy being of one quarter of a diopter. The present paper aims atcomparing the pronciples on which the above said three techniques are based. The main difference seems to lie in the fact that the apparent movement of the laser speckles, denoting a situaion of defocus, does not stimulate the accommodation reflex as the sensation of blur does.
