Abstract
A method of sealing lenses includes the steps of grinding the edges of at least two lenses, cleansing the lenses, positioning the lenses next to one another, applying an adhesive to the ground edges of the lenses and placing the lenses in an oven to cure the adhesive to produce a laminated, hermetically-sealed, lens.
