EYE REFRACTING FORCE MEASUREMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an eye refracting force measurement device for obtaining a distance between pupils at the time of far sight and near sight. SOLUTION: This eye refracting force measurement device 312 is provided with a left eye refracting force measurement unit 319L and a right eye refracting force measurement unit 319R capable of the objective and subjective measurement of a customer 407 and the respective units 319L and 319R are provided so as to be driven at least to the left and right by independent three-dimensional driving devices 3177L and 317R respectively. The eye refracting force measurement device is provided with horizontal rotation devices 318L and 318R for respectively independently and horizontally turning the respective eye refracting force measurement units 319L and 319R and an arithmetic control circuit 315a for obtaining the interval of both units 319L and 319R and a measurement optical axis angle from the driving amount to the left and right and horizontal turning amount of the units 319L and 319R and obtaining the distance between the pupils of the left and right eyes of the customer 407 from the internal.
