Solutions for use in ophthalmic lenses

A solution applied to an ophthalmic lens comprises a first hyaluronic acid or a salt thereof, a second hyaluronic acid or a salt thereof and a solvent, the molecular weight of the first hyaluronic acid or the salt thereof is between 100 kDA and 6000 kDA, the molecular weight of the second hyaluronic acid or the salt thereof is less than 100 kDA, and the solution is applied to the surface of the ophthalmic lens. Wherein the contact angle of the ophthalmic lens is C1 before the solution is applied to the ophthalmic lens, the contact angle of the ophthalmic lens is C2 after the solution is applied to the ophthalmic lens and is used for a period of time, and the solution meets the following range: (C1-C2)/C1 * 100% is more than 16% and less than 61%; therefore, when the solution is applied to the ophthalmic lens, the timeliness of the ophthalmic lens for maintaining water replenishing and moisturizing can be prolonged, so that a wearer can still maintain a comfortable wearing effect after wearing the ophthalmic l
