An eye care company has been warned by the Information Commissioner's Office to stop sending out nuisance text messages or face further action.

Over 4,600 people registered concerns about Optical Express (Westfield) Limited in just seven months reporting the unsolicited messages to the Mobile phone networks spam text reporting service indicating they had not given permission for the company to use their details for marketing.

The Glasgow-based business which has branches across the UK had been sending out texts that included details of a competition to win free laser eye surgery.
