sorry folks forgot to add to my last post ...I had my retinal screening yesterday at my local hospital eye clinic, i have it there as I have ongoing eye problems not retinopathy but something called AION (anteria iscemic optic nueropathy)...I had 2 drops in each eye , the first one was painless but the second one was extremely uncomfortable it really stung ...my question is it is now more than 24 hours and my vision is still very blurry is this normal i have had to try and avoid the sunlight today because of the glare .....PS no eye problems detected , at least that was ok ...thanks ..
