Abstract
An exemplary a method for manufacturing a lens is provided. In the method, a first lens preform and a second lens preform is formed. The first lens preform includes a first surface and an opposite second surface. The second lens preform includes a third surface and an opposite fourth surface. An oxygen plasma is applied to the second and fourth surfaces so as to form a number of groups capable of being irreversibly bonded. The second surface is contacted with the fourth surface. The groups capable of being irreversibly bonded take place an irreversible bonding reaction to chemically combine the second and fourth surfaces, thereby obtaining a double sided lens preform. The double sided lens preform is diced into a number of double side lenses.
