We employ our own staff to monitor the quality at the factories our suppliers; so we can ensure that the production process comply with our quality standards.

In the group's own testing facilities (certified in accordance with ISO 9001:2000), Filtral’s sunglasses and reading glasses are tested well beyond the requirements of the international standards. Under laboratory conditions, tests are conducted, for example, on mechanical loading and physical properties.
