“When exposed to our AR low vision aid, which encodes distance as discrete color bands, even people who were totally colorblind using clinical tests were able to differentiate between different depths,” Anastasios N. Angelopoulos, BA, a PhD student at the University of California Berkley and co-founder of MHR Vision, told Primary Care Optometry News. “This is surprising and could be due to the different grayscale intensities of colors.”
