Effect of controlling optical wavelength by spectacle lenses on visual quality

In this study, the effects of selectively yellow-cut lenses on contrast sensitivity were investigated in healthy young and middle-aged individuals and elderly patients with cataract. Contrast sensitivity in middle-aged healthy individuals and elderly patients with cataract was higher when measured while the subjects were wearing selectively yellow-cut lens (NeoContrast; Mitsui Chemicals, Inc., Tokyo, Japan) compared to no yellow-cut lens. Controlling optical wavelength could provide an improved quality of vision through improved visibility.
