—In "Adrenochrome Pigmentation of Hydrophilic Lenses" in the January Archives (91:11-12, 1974), Joel Sugar, MD, demonstrates the rapidity with which the Griffin Naturalens can become discolored. This does not seem to be the case with the Bausch and Lomb Soflens.A 27-year-old woman with a dense congenital corneal leukoma had been treated with corneal tatooing and an opaque hard contact lens to decrease the disfiguring appearance of her white cornea. When referred to me, she was no longer able to tolerate the hard lens. Since the Soflens was comfortable, I attempted to color it brown. Using 0.5% epinephrine (Eppy), which was left exposed to sunlight until it turned almost black, I attempted to impregnate the lens with this dark color by soaking the lens in the solution. The first try required about seven weeks to get a mildly brown color, which was not dark enough to cover
