I went last year to Optical 88 in Causeway Bay (they seem to have branches all over the place) and they gave me a very thorough eye test there and then. They told me what I needed and gave me a written prescription that I could take anywhere, or ignore. I was under no pressure to return there to buy glasses from them and they did not charge me anything for the test. I think that was normal procedure for them.
Perhaps if you can get your helper in for a test (free) then you will know if that is the problem. Alternatively, perhaps she should just go and see the doctor first to check that it is nothing else (dietary imbalance etc). Afterall he can carry out a basic eye test.
