claiming for an eye test?

[Jackleman]

Hi,

I work on a computer from about 8am to 5pm - mon to fri with an hour for lunch.

I just had my eyes tested as I've been getting headaches and sore eyes, I have to wear glasses now.

The eye test cost £20 and I was told I could claim this back from employer, the question is.... is this correct? and then is it a little bit tight for me to want to claim 20 quid back? do other claim theirs back?

Cheers
