Abstract
A method for strengthening glass and a glass using the same are provided. The method for strengthening glass includes the following steps. Firstly, a glass substrate, which has a first surface and a second surface opposite to the first surface, is provided. Next, a barrier film is formed on at least one of the first surface and the second surface. Then, the glass substrate with the barrier film is immersed in a strengthening solution. The strengthening solution includes first ions, and the barrier film can limit the first ions in the quantity entering the glass substrate.
