The brothers held the positions of joint managing directors in the transition period following the August 2014 acquisition of the company by the CooperVision group but have now handed over their responsibilities and have departed the business.
A statement from the two said: "We have each spent more than 22 years in the business, and we are looking forward to new challenges ahead. Although we are sad to be leaving Sauflon, we are proud to have been part of a strong business that will continue to succeed as part of the wider CooperVision group."
President of CooperVision, Dan McBride, commented: "We are grateful to David and Bradley for all of their hard work, and for their part in helping to create a strong market-leading business. We wish them all the best in their future endeavours.
