title: Changes in the hydration of hydrogel contact lenses with wear.
abstract: This study examined the short-term hydration changes of hydrogel contact lenses with wear. Changes in the water content of 12 new Bausch & Lomb hydrogel contact lenses were calculated from the change in weight of the lenses after they were worn. The mean of the calculated water contents after wear was 27.9%. This compares with the 38.6% water content of new, fully hydrated lenses.
