ISTANBUL, Turkey — Specially customized color spectrum-correcting lenses may readjust color perception in color-blind individuals, a physician said here.
"A significant number of men and women suffer from color perception deficiencies, but up to now no satisfactory treatment has been available," Mitsugu Shimmyo, MD, said at the winter meeting of the European Society of Cataract and Refractive Surgeons.
A novel computerized diagnostic tool was used to assess color perception deficiency and to provide the data for the creation of individually customized lenses.
The lenses were fitted in 300 dichromatic individuals in a clinic in Shenyang, China. In a separate study, 10,266 men out of 200,000 military service candidates were identified as color perception deficient and analyzed with the computerized device.
"In many dichromatic eyes, two out of three cones function normally, and the third has attenuated function to different degrees. Our lenses rebalance color perception by filtering and redistributing the intensity of color spectrum," he said.
