CONSTITUTION:An eye drop consisting essentially of oxidation type glutathione or a salt thereof (e.g., metallic salt such as Na or Ca or organic amine salt). When the eye drop is administered, oxidation type glutathione is changed into reduction type glutathione by action of glutathione reductase in crystalline lens and an amount of the reduction type glutathione in crystalline lens is increased to prevent opacification. The concentration of the reduction type glutathione in crystalline lens is preferably 0.5-5% and pH of the eye drop is preferably 4-7.
