Change in weight of the human lens with age.

When data in the literature are pooled, a large number of points become available for plotting the weight of the human lens as a function of age. Between mean ages 15 and 85 years, the values are described by L = 1.32 A + 141, where L is the Lens weight in mg and A is the age in years. The correlation coefficient was 0.977. There thus appears to be a continual, linear increase in the weight of the lens with age.
