Sense of Vision is very important as about 80% of the information which we get through all the senses, is visual. This information become more meaningful and informative when these are colourful.
The study was carried on 60 ocular healthy subjects. They were divided in two groups. First group was having 30 male individuals while second group was having age matched 30 female individuals. Exclusion criteria was any previous or present eye and colour vision related problems. The task was to match 25 colour strips with 2 shade charts of different colours.
It was found that females gave more correct responses as compared to males and this difference was statistically highly significant
In human retina, three types of cones are there: short wavelength (blue) sensitive cones, medium wavelength (green) sensitive and long(red) wavelength sensitive cones. Different wavelength of light stimulate this cones with different intensity. At the end we conclude that females can discriminate more shades of colors than males.
