OBJECTIVE PATIENT VISION COMPARISON PROCESS AND APPARATUS

摘要

A segmented objective vision test (40) is administered to a patient for determining a quantitative measurement of vision capability in the test segments. Human vision can be tested in separate segments of total vision spectrum including contrast sensitivity (14), or color sensitivity testing. Thereafter, an emmetropic real world image (IR) is filtered into corresponding emmetropic segments. These corresponding emmetropic image segments are degraded into degraded image segments in correspondance 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 obective vision test and the subsequent image processing.
