Hi

I feel I sometime see blurry or double vision. I haven't really had it, but sometimes letters on my PC are a very tiny bit blurry but can still be read. It's quite strange also, I take my glasses of when walking to read things at a grater distance. I am so confused and worried in case there is something wrong with my eyes.
I recently got new glasses and had an eye appointment about a month ago and the optometrist said my eyes hadn't change at all (appointment before this was three years ago). Just worried all of a sudden there's been a sudden change in my eyes.

Thanks
