The purpose of this dissertation in one hand is to review the literature of color research, including patents filed by Budapest University and Technology and Economics. On the other hand to come out with a novel method, which makes the lens development process easier.
In order to be able to examine this issue, having knowledge in the operation of human color vision is necessary. There are three photoreceptors on the retina with three different sensitivities that are responsible for color vision, and these sensitivities are heavily dependent on the effects of different lights.
In this dissertation I demonstrated the color vision correction effect of certain type of correction lenses in the OCS (organic color sytem). Through the entire modelling process I applied one of currently worldwide accepted color adaptation methods. In the 5th chapter of the dissertation I modeled the color correction effect of the currently existing lens types in case of different color deficient patients, demonstrating the color vision improvement in each case. As a part of this modelling I built a model for implementation of the previously introduced D15 test on neurological processing level. Applied this methods I was able to demonstrate the color vision correction effect in terms of color identification and discrimination as well.
In the further chapters of the thesis I came out with an improved adaptation method, which already considers the limit of human eye’s adaptation level. All the further results, are calculated with consideration of this new adaptation method. In favor of objective evaluation of correction effects, in the 8th chapter I came out with a new index-number which provides information about the red-green gamut of the color filters and makes the lens correction effect comparable on objective way. In the last chapter, based on the new qualifier value, I created a new transmission spectrum optimizer algorithm. Thanks for these results it seems to a realistic goal to develop even more efficient correction lenses in the future.
