According to a recent Medgadget article, a research team at the UCSD has developed a smartphone attachment aimed at providing accurate measurements of pupil size changes, particularly for those with dark irises. Changes in pupil size can offer valuable information about neurological conditions like traumatic brain injury and Alzheimer’s disease. However, distinguishing between iris and pupil in individuals with dark eyes has been challenging. The smartphone attachment utilizes a filter to restrict camera light to far-red light, making the iris appear lighter in images.
