Zusammenfassung:	PCT No. PCT/GB84/00311 Sec. 371 Date May 14, 1985 Sec. 102(e) Date May 14, 1985 PCT Filed Sep. 12, 1984 PCT Pub. No. WO85/01209 PCT Pub. Date Mar. 28, 1985.Hydrophilic soft contact lenses are disinfected by soaking in a non-eye-irritant aqueous disinfecting solution obtained by the addition to tap water of a chlorhexidine salt, a sequestering agent for calcium and magnesium ions, and a dechlorinating agent. Suitably, the solution is obtained by dissolving a tablet in tap water. The preferred sequestering agent is sodium tripolyphosphate and the preferred dechlorinating agent is sodium thiosulphate. Advantageously, the chlorhexidine salt is provided in solid solution in urea to assist complete dissolution.
