ABSTRACT:
The present invention is directed to a quantitatively analysis method for the phenomena of glare. The method includes the steps of reading light source picture information from a memory part and displaying the light source picture on a display part, reading position information of the circumference of the glare when a patient suffering from the phenomena of glare draws circumference line of the glare by means of a pointing device and calculating area of circumference of glare and outputting the calculated area. The output of the area indicates the condition of illness and the degree of remedy of the patient.
