Siltint has been coating ophthalmic lenses for more than 30 years, starting with tinting of glass lenses in 1972. During the 1970s and 1980s the company developed AR coatings initially for glass lenses and then plastics as the ophthalmic market began to evolve.

In the late 1980s Siltint created a precision optics business unit and in 2000 purchased a diamond-turning firm, allowing the company to produce customised precision lenses.

The company has become a key UK supplier for special products such as polycarbonate reflectors and diamond-turned plastic lenses. The knowledge gained from dealing in both ophthalmic and precision optical coatings has led to a key strength in dealing with plastic optics.
