“…Nevertheless, protans make fewer errors on screening plates than deutans [28,44,45]. Arrangement tests such as the PD-15 can more easily be used in case of reduced visual acuity and that is why they are very useful in studying acquired colour defects [30,41,46]. However, in acquired CVDs combined patterns of CVDs can be seen, and the distinction between protan/deutan or tritan/tetartan is often difficult when there is a small number of crossings [31].…”

“…One may argue that the 6.25 times greater surface area of the LV PD-15 allows cones in the peripheral macula and/or perimacular midperiphery to detect colour vision, at a time when central macular cones have already been lost. If the patient uses his midperipheral field instead of foveal fixation to perform colour vision tests, the PD-15 can be normal, even in the later stages of disease [54]. …”

Purpose: To investigate the type and severity of acquired colour vision deficiencies (CVDs) in molecularly proven Stargardt disease (STD) and to establish whether a relationship exists between best-corrected visual acuity (BCVA) and full-field electroretinography (ffERG), and the degree of CVD. Methods: A retrospective, cross-sectional study of 73 patients with a molecularly proven diagnosis of STD, who underwent extensive colour vision evaluation, using pseudo-isochromatic and arrangement tests. Thirteen patients underwent Nagel anomaloscopy. Results: Normal colour vision was found in almost 20% of patients. Red/green (R/G) CVDs increased as BCVA declined. About 45% of all R/G CVDs were of the deutan type, although protan type CVDs became progressively apparent when moving from the high to the low BCVA group. An additional blue/yellow CVD was noted in about 25% of patients. In 10/13 patients, a pseudoprotanomaly was noted on anomaloscopy. Severe CVDs leading to scotopization were noted in patients with low BCVA and/or long-standing disease. No statistically significant differences in ERG results were found between groups with or without a CVD. Conclusions: The degree and type of colour vision deficiency in STD patients correlate better with BCVA than with ffERG results. The presence of specific CVDs may help to establish a diagnosis of STD. A battery of colour vision tests is required to properly evaluate CVDs in STD.

Spectral Sensitivity Measurements in Early Diabetic Retinopathy

1980

Patients with early background diabetic retinopathy and good visual acuity may have normal results on standard methods of measuring color vision. Measurement of individual spectral sensitivity functions shows a moderate decrease in sensitivity of the blue-sensitive receptor system. These results suggest that the blue-sensitive cone mechanism is affected earliest in mild background diabetic retinopathy and that disturbances in its spectral sensitivity function may precede other disturbances of macular function.

“…The cones that are affected by various drugs and medical disorders vary. Specifically, diseases that cause lesions in the deeper layers of the retina result in a reduction in the blue-yellow responses, whereas victims of damage in the ganglion layer or the optic nerve mainly suffer from changes in the red-green senses [35]. Age can also be a contributing factor to a change in one's color vision.…”

There are numerous different dyes available, many varied fashion trends, and various different ways to change/enhance physical aesthetics. Predicting color preferences and how colors and color combinations, in a shape context, stimulate certain emotions, represents a challenging prospect. Color is a critical cue for sexual signaling, but what the preferred colors actually are in humans, is difficult to predict. Understanding color preferences and perception of color within a context such as attraction, is essential for improving color forecasting and gaining a deeper understanding of color perception. The appearance of color can change based on lighting, shape, texture, and the surrounding environment and associated colors. While these provide physical color characteristics, human vision and perception contributes to how a color appears to the individual. Perception is unique to each individual and is constantly changing due to the influence of a range of variables. This can cause someone to appear visually attractive or visually unattractive. By taking into account all the variables that contribute to human studies in color perception, tailored research can continue to be undertaken to further develop a deeper understanding of color perception and human attraction regarding visual stimulation. and their longer-term mates (i.e. husband/wife/partner, fiancé, longterm relationship) to be physically attractive [5]. For heterosexual groupings, studies have shown that when evaluating a female's attractiveness, men focus not only on physical cues such as facial expression and body language but also on the type and color of their clothing [6]. KeywordsFor centuries, females have been attracted to the use of color. In the 1930's, Korda et al. [7] stated that color was particularly attractive to female cinema audiences. Yevonda, in the 1930s, stated that women were more attached to the use of color photography than were men as the medium was better able to highlight visible signs of the times, such as red hair, uniforms, flawless complexions and cosmetic combinations (lips and colored finger nails) [8]. Such use allowed females to express themselves more fully [8]. Females use color in a variety of different ways including adding beauty to their aesthetic characteristics. The use of colored make-up, accessories, tattoos, hair colorants and clothing are among ways of enhancing physical appearances. However, it is not uncommon for men to use color in certain ways to change their physical appearance, increasing their potential to attract a potential partner.These colors and color combinations, that women see and perceive as being important in increasing their physical attractiveness, can be different to those that males find attractive. Questions have arisen concerning the role color plays in human attraction. To appreciate the significance of these questions, a basic understanding of how color is created, how the human visual system works, how the brain perceives color, what attraction is, the role of color in fash...
