  • Moisturizing composition of a contact lens
    Patent number: 10953614
    Abstract: A moisturizing composition of a contact lens is disclosed in the present invention. A rinse agent (ex. TEOA) is applied for bonding a moisturizing stabilizer (ex. HPMC) and a compound of a hydrophilic cosolvent (ex. PEG) and a moisturizing additive (ex. HA). Hence, the solubility of the moisturizing additive and the aqueous solution can be improved via applying the hydrophilic cosolvent; the stability of the combination of the moisturizing stabilizer and the moisturizing additive can be improved via the structural and the chemical stabilities of the moisturizing stabilizer itself. Meanwhile, the moisturizing composition disclosed can be directly applied to the raw material of the conventional contact lens during manufacturing the high-moisturizing contact lenses.
