History – the Lenstec Timeline


Formed by three local independent opticians to serve the local South Wales optical industry.

Nigel Castle, the current MD, joined the company to broaden the services offered.

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.

Appointed as one of only two laboratories in the UK working with Seiko Optical UK.

Undertook a major investment in robotic glazing machinery at both sites, making Lenstec a laboratory focused on quality and becoming a leading supplier of surfaced and glazing services throughout the UK.

On September 6th Lenstec acquired Tant Laboratories, located in Bishop’s Stortford, Hertfordshire, in the South East of England, to strengthen its position in serving the independent optical market.

On 31st March Lenstec Optical Group acquired Rawdon Optical, situated in Leeds. The Lenstec Group now strengthens the independent supply route through its three locations; with Lenstec in South Wales, Tant in Hertfordshire and now a northern presence in Leeds.

In November 2015 Lenstec invested in new 5 Axis edging programme, installing MEI Bi Sphera TBA production into Tant Optical Laboratory and MEI 641 TBA and NIDEK SE-1 RHU dry edging to strengthen Lenstec’s Bedwas production. The £500k investment strengthened the commitment to dry edging and sports eyewear development to the UK and Europe.

Lenstec Optical Group are proud to announce that they have been awarded certification for the EN ISO 13485:2016 Medical Devices Standard.

“This standard involves a stringent and intensive 10 day audit of all our procedures, culture and supply chain across the business” says Nigel Castle, Lenstec Optical Group MD. “EN ISO 13485:2016 is much harder to accomplish than ISO9001 so to achieve this highly prized accreditation there has been 18 months of dedicated hard work by Paul Kibble Group Quality Manager, Chris Kellard and the management teams across all sites.” Nigel adds “The auditors were very complimentary of every member of staff they spoke to and were impressed with the culture and work ethic evident throughout the business.”

Lenstec Optical Group is believed to be the only optical manufacturing lab in the UK to have attained this highly acclaimed standard. The company has also just been audited for the Investors In People 6th Generation Standard and is due the award shortly.
