Richardson等曾经指出:商业上用于软接触透镜消毒的溶液在贮存期间所含抗菌药的浓度越来越低.这种溶液常常用聚乙烯容器包装,虽然塑料与防腐剂相互作用能引起抗菌浓度降到低于有效水平是有文可查的.一般都认为玻璃不容易发生化学变化,但有关玻璃适于做为软接触透镜溶液容器的报告则极少. Richardson et al. Have noted that solutions used commercially for disinfecting soft contact lenses are getting lower concentrations of antimicrobials during storage, often in polyethylene containers, although plastic and preservative interactions can cause antibacterial concentrations It is well documented that the glass is less susceptible to chemical changes, but reports on the suitability of glass as a container for soft contact lens solutions are rare.
