To provide a contact lens storage solution improved in comfort, a contact lens packaging method, and a contact lens package.

A contact lens storage solution comprises a thickening agent and an alkali metal salt and has the pH of 6 to 8 and the osmotic pressure of 100 to 400 mOsm/kg and has viscoelastic properties even if sterilized by autoclaving. The thickening agent is selected from alkali metal salts such as hyaluronic acid, poly (acrylic acid), crosslinked poly (acrylic acid), poly (methacrylic acid), carboxymethyl cellulose, alginic acid. The alkali metal salt is selected from sodium chloride, sodium bicarbonate, sodium dihydrogen phosphate, disodium hydrogen phosphate, trisodium phosphate, sodium tetraborate, sodium citrate, sodium acetate, sodium lactate, potassium chloride, potassium bicarbonate, potassium dihydrogen phosphate, dipotassium hydrogen phosphate, tripotassium phosphate, potassium tetraborate, potassium citrate, potassium acetate, potassium lactate, etc.
