  • Patent number: 5552842
    Abstract: A segmented objective vision test is administered to a patient for determining a quantitative measurement of vision capability in the tested segments. Human vision can be tested in separate segments of the total vision spectrum including contrast sensitivity, or color sensitivity testing. Thereafter, an emmetropic real world image is filtered into corresponding emmetropic image segments. These corresponding emmetropic image segments are degraded into degraded image segments in correspondence with the separate test results for each corresponding separate segment of the total vision spectrum. The degraded image segments are then added to produce an objectively altered real world image. This objectively altered real world image can then be compared to the real world image of the emmetrope and a record preserved of the patient's actual vision condition as evidenced by the objective vision test and the subsequent image processing.
