A family laboratory that became a specialty lens maker.
Silver Line started as Sahni Contact Lens Laboratory, set up in 1991 by four brothers in a small part of their family home in New Delhi. It became known for its choice of lenses, for customisation and for service, and grew into Purecon.
As practitioners asked for more customised and specialised lenses, Purecon launched Silver Line to make them. We have worked on new lens design geometries ever since, and today our lenses are cut and finished at our facility in Bawana, Delhi.
