1. In a process for measurement and recordation of actual image visibility by a subject compared to a preselected standard of image visibility by another subject having differing image visibility, the steps comprising: selecting an image; selecting a vision test having capability of detecting vision sensitivity in at least one segment of a preselected vision channel; testing the vision sensitivity of the subject in the at least one segment of the preselected vision channel to generate test results for the at least one segment of the preselected vision channel; filtering the image into at least one image segment corresponding to the at least one segment of the preselected vision channel; changing the at least one image segment corresponding to the test results for the at least one segment of the preselected vision channel to produce a modified image segment; replacing the at least one image segment with the modified image segment to produce a composite modified image including the modified image segment; and, displaying the composite modified image to emulate actual vision of the subject.
