A material for manufacturing contact lenses comprises a first composition, a second composition, at least one hydrophilic monomer and at least one photoinitiator. The first composition and the second composition are respectively represented by the following formula (1) and formula (2). Z1 is a first silicone hydrogel monomer, n1 is ranged between 1 and 1.5, and o1 is ranged between 1 and 2; and Z2 is a second silicone hydrogel monomer, n2 is ranged between 1 and 5, and o2 is ranged between 1 and 2.

Material for manufacturing contact lenses and contact lens thereof

The present invention provides a hydrophilic coating method for contact lens surface, firstly performing a hydration procedure Sto form a hydrated polymer from a non-hydrated polymer, then sequentially contacting the hydrated polymer with a first solution and a second solution containing a high molecular compound at a specific temperature between 50&#xb0; C. and 70&#xb0; C. to complete a first hydration process Sand a second hydration process S. A contact lensobtained according to the above procedures has a contact angle ranging from about 30&#xb0; to 65&#xb0;, and proteins and lipids are not easily deposited on a surface of the contact lens, thereby providing the user with good comfort when wearing.

Hydrophilic coating method for contact lens surface

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.
