THE number of people taking eye tests in Scotland has increased since they became free, but the gap in uptake between rich and poor has also risen, according to researchers.

A study by economists at Aberdeen University looked at the impact of free eye tests, introduced in 2006, on the uptake of eye care. They found there was an rise in Scots taking the opportunity for eye examinations, but the majority of those came from wealthier backgrounds.

Dr Alexandros Zangelidis, who led the study, said: "Our analysis suggests people with low education and those from poorer households not only have overall lower levels of eye examinations, but had a weaker response to the policy when compared to educated people and those from wealthier households. As a result, the inequality in eye care utilisation in Scotland has risen."

While Scotland's uptake still lags behind the UK, the free test policy has helped reduce the gap. In 2005, 32.1% of Scots had an eye test com-pared to 35.1% in England. By 2008, 36.2% of Scots were taking eye exams compared to 37.3% in England.

However, Dr Zangelidis suggested a fear of being made to pay for further services could deter poorer people from using the service.

A Scottish Government spokesman said: "We welcome the report of Aberdeen University's study into Scotland's free eye examination policy and will consider the findings to help us ensure our eye care policies continue to meet the needs of the people of Scotland."
