Low vision measuring instrument










Image Number 4 for United States Patent #6802608.

Light is emitted to each of right and left eyes, the emission of light is controlled according to light stimulation steps defined by a combination of light intensities and light emission times, and presence or absence of reaction of a test subject to light is detected at the respective stimulation steps. When reactions, the number of times of occurrence of which is a predetermined number of times of occurrence and less, are detected at a given stimulation step, the given stimulation step is regarded as not being viewed, and tests are omitted which would be effected at stimulation steps lower than the given stimulation step by a predetermined number of steps, whereas when reactions, the number of times of occurrence of which is a predetermined number of times of occurrence and more, are detected at a given stimulation step, the given stimulation step is regarded as being viewed, and tests are omitted which would be effected at stimulation steps higher than the given stimulation step by a predetermined number of steps.
