As a DSE user, I'm entitled to free eye tests via work. In certain circumstances I can also get part of the cost of specs paid.
The thing is, because it's through work (a local authority), I will take advantage, where I can, of anything they provide FoC. After all, they don't give us much. The maddening thing is that although my colleagues feel the same way, they are just so apathetic when it comes down to it. As DSE assessor, I give out the forms for free eye tests, but no-one takes advantage - not even those at most risk.
