Lenstec invested in producing plastic and glass lenses for glasses while providing a local van service across south and west Wales.

Moved to the outskirts of Caerphilly and expanded its services across the UK.

Developed a second purpose-built modern factory to support its growing client-base and service levels.

Became an accredited ISO 9000 laboratory and undertook a modern management restructuring. Lenstec also introduced an accredited Investor in People culture across the business.

Became sole distributors for a leading German sports lens brand and a leader in corrective sports eyewear.
