[holding answer 4 June 2007]: All children under the age of 16 are entitled to national health service sight tests and vouchers for optical appliances, as are children aged 16, 17 and 18 who are being educated full-time in a recognised educational establishment. The Department has not previously issued specific guidance on this subject. Where children aged 16 to 18 are being educated at home, the local primary care trust would need to seek advice from the local education authority to assess whether these arrangements are comparable to full-time education in such an establishment.
