Analyzing the effect of blue-blocking lenses on color vision tests using the chromaticity coordinate method [PDF]

open access: yesHeliyon
Significance: Blue light with wavelengths of 380–445 nm can harm the retina, leading to the development of blue-blocking lenses (BBLs). Understanding whether BBLs affect color vision test outcomes and color discrimination ability is crucial for people in
