I went for an eye test yesterday at Specsavers I'm currently 33+6 and was diagnosed with Idiopathic Intracranial Hypertension (I.I.H) in March 2013 so get them done at least once a year.
They took the prescription from my previous glasses in my bag which where;
Sph Cyl Axis
R +0.50 -0.50 119
L +0.50 -0.50 92
Now they've given me this prescription and told me I've gone from being long sighted to short sighted in the space of around 12 months;
Sph Cyl Axis
R 6/10 -0.25 -0.50 90
L 6/10 0.00 -0.50 90
When I was picking them up the man seemed really surprised and said that that was a massive jump, I asked for a copy of my prescription so I could ask Vision Express who had done my last copy and they were really funny with me. They actually refused for about 5 minutes before just writing it down (I managed to take a photo when he left the desk of what the long piece of paper said)
Is this normal? my I.I.H has been under control since March, no medication and eyes have generally been fine. He didn't seem concerned when I mentioned I keep seeing little round black dots that blank tiny bits out they don't move so I don't think they're floaters but it doesn't happen a lot but almost daily I notice like black thins at the top, bottom or corners of my eye moving, kind of like catching a spider making a run for it across the floor/ceiling/bed and when I look there's nothing there.
I know to look out for the curtain/veil of blackness or bright shooting lights which haven't happened I just don't know whether to trust this prescription, I don't know what any of this means so I'm kinda clueless
