Optician told me last year that ds had a slight prescription and they would see how things were at next appointment, roll on to this appoint and they say that again there’s a slight prescription but seen as he’s coming up to year 1 it may start to become more noticeable (headaches etc) with the increased work so they’ll give him glasses for 6 months just to see how he goes.
Went for the fitting today and the optician said oh not to worry he just had a slight astigmatism,
I’ve googled it and it doesn’t seem like the type of thing that goes away in 6 months 
Can anyone offer any words of wisdom or advice please?
