I received your response and you recommended that I go for eye testing, my question now is I'm in South Africa to be specific I'm based in Pretoria. I was checking the nearest stores in the site but couldn't find any, please provide the list of the stores you have in Pretoria.

There are no Specsavers stores in South Africa. I believe there are practices with the same name, but they have no connection with the Specsavers Optical Group.
