Different dyes were used to tint Soflens contact lenses. The light transmission of each lens was measured before and after tinting and after asepticizing it in fresh saline from 1 to 15 times. Crystal violet was found to be the dye most stably retained within the lens after saline asepticizing. By asepticizing hydrophilic lenses in solutions of food coloring, we found that the amount of dye retained by a lens was not cumulative and the transmittance was maintained at approximately the original value. Tests of these tinted lenses for toxicity to animals or human subjects were not performed, nor did we ascertain whether these dyes affect the durability or hydrophilic and wetting properties of these lenses.
不同的染料被用于给Soflens隐形眼镜染色。在染色前后以及在新鲜盐水中无菌处理1至15次之后，测量了每个镜片的透光率。发现结晶紫是在盐水无菌处理后最稳定地保留在镜片内的染料。通过在食用色素溶液中对亲水性镜片进行无菌处理，我们发现镜片保留的染料量不是累积性的，并且透光率保持在大约原始值。未对这些染色镜片进行动物或人体毒性测试，我们也未确定这些染料是否会影响这些镜片的耐用性或亲水性及湿润性能。
