## 5 Conclusions  
The main question of our research was whether anomalous and normal trichromats can be distinguished based on eye movements under different conditions of luminance and chromatic contrast sensitivity. Following our research questions, we concluded the followings. 1. Which statistical method is suitable to model the differences between the number of right answers of anomalous and normal trichromats? The differences between the answers of anomalous trichromats and normal trichromats can be modeled with statistical methods. The right answers of anomalous trichromats and normal trichromats can be described with multiple or cross-classified contingency tables. For comparing these parameters, Scheirer-Ray-Hare (SRH) test can be applied. 2. Which of eye movement variables have significant effect on the parameters (image, success and subject) and their interactions? We identified the variables of the eye tracking that have significant effect on the parameters (image, success, subject and ordinal number). In the case of the observation of Landolt-C figures, the variables related to fixation duration, fixation count, visit duration or visit count significantly affected the subject, success or image parameters and their interactions. In the case of observing the hiatus of the Landolt-C figures, the time to first fixation was significant, meaning that, if someone recognizes the hiatus, he or she looks at that instantly. 3. Is there any significant difference between eye movement variables of normal and anomalous trichromats? The estimate for the success x ordinal number parameters validated the design of the test: As the Landolt-C figures get more difficult to distinguish from the background, the chance of success decreases by 3.5% in average, so the chance of failure increases. 4. How does the survival time of anomalous and normal trichromats change in the case of achromatic and colored figures? Besides the results of the eye tracker variables, differences between normal and anomalous trichromats was traced also. In the case of achromatic image series, the chance of success for anomalous trichromats is 5.93-fold than that for normal trichromats. The survival functions of normal and anomalous trichromats go in different ways in the case of colored and achromatic images. Based on the results of the survival analysis, normal trichromats are more successful in colored images; that was proven with statistical methods as well. Conversely, the survival function of anomalous trichromats shows that they are more successful in achromatic images that can be explained with the assumption that their luminance contrast sensitivity is better, as they have to be able to discriminate smaller luminance differences in everyday life. The limitation of our study was the low number of anomalous trichromats, even though the applied loglinear analysis handles the asymmetry between the two groups well (normal and anomalous trichromats). Note the importance of the experimental design, including both the environmental parameters (such as lighting conditions and the relative position of the stimuli and the subject) and the visual stimuli (such as the appropriate colorimetric design of the figures and calibration of the display following corresponding standards). Based on our conclusions, we recommend applying eye-tracking methods in combination with pseudoisochromatic tests, for testing color-vision deficiency, in practice.
