Following his retirement from Welsh rugby, Doug Perkins, the famed former Llanelli player, devoted his energy to the management of Specsavers, the large chain of optical shops which he had founded. In 2002, as part of a sponsorship deal, Specsavers offered free eye tests to select members of the Welsh Rugby Union who Perkins thought could use some extra help: Welsh Rugby Union referees.
(At the time, referees were subjected to so much verbal abuse that attendance numbers at coaching courses were down 50%. Specsavers paid £1 million to display the firm's name on referees' shirts for four seasons.)
