Males had higher anterior corneal radii of curvature (0.16 mm), lower lens equivalent refractive index (0.006), longer vitreous lengths (0.51 mm), and longer axial lengths (0.62 mm) than females. Despite considerable data scatter, we found significant age changes: anterior chamber depth decreased 0.011 mm/year, lens central thickness increased 0.024 mm/year, anterior segment depth increased 0.013 mm/year, eye length increased 0.011 mm/year, anterior lens radius of curvature decreased 0.044 mm/year, and lens equivalent refractive index decreased 0.0003/year. One eye was tested for each subject, having spherical equivalent in the range −0.88 D to +0.75 D and ≤0.50 D astigmatism. There were approximately 20 subjects each in age groups 18–29, 30–39, 40–49, 50–59, and 60–69 years with similar male and female numbers. We measured optical and biometric parameters of emmetropic eyes as a function of age.
