Color vision and contrast sensitivity are also affected by aging. Color vision changes cause some reduction of ability to discriminate blues and blue-greens. The yellowing of the lens is believed to be responsible for this effect. The aging lens and cornea causes glare by light scattering, especially for shorter wavelengths. Stray light and lenticular fluorescence washes out contrast. (Reference: Work, Aging and Vision. National Academy Press; 1987). Contrast sensitivity shows a significant age-related decline (Ophthalmic Physiol Opt 2000;20:323-34). Wavefront aberrations of the cornea also increase with age, leading to poor vision quality especially when the pupil dilates as in the dark (Invest Ophthalmol Vis Sci 1999;40:1351-5)
