Study uses arrays of multicoloured disks to demonstrate colour perception in peripheral vision
Some common science-related misconceptions are particularly persistent, such as a duck’s quack doesn’t echo, or that we only use 10% of our brains.
Now new research from City University London is aiming to dispel a long-held misbelief relating to colour vision: that it is weak or non-existent in our periphery vision.
“This misconception about weak peripheral colour vision is completely incorrect,” said Professor Christopher Tyler, a visual neuroscientist at the university’s School of Optometry and Vision Science, who carried out the study.
“Although the number of cone photoreceptors is lower in the periphery than in the fovea, with about 4000 cones per mm2 throughout the peripheral retina compared to 200,000 in the central fovea, this is still plenty enough to give colour vision,” said Professor Tyler.
