Prior to 2006, General Ophthalmic Service (GOS) arrangements in Scotland and England were similar. GOS eye examinations were not universally available and were only 'free' for those patients aged under 16 years of age; 19 years and under if in full-time education; 60 years or over; having a low income level; or if they qualified due to having certain conditions such as visual impairment, diabetes or a family history of glaucoma. Legislative requirements for the examination procedure were also the same across both countries and were defined by the Opticians Act (1989).
