Just wondering if it is me or whether other people get it where if youre using an SLR or the viewfinder on a camera, your other eye gets a bit strained and blurry for a bit afterwards?

My left eye is my "lazy eye" where its 0.5 out and seems to not focus quite as quick as my right eye, but normally its fine. When I use my SLR, even for just a few minutes though, it makes my left eye go a little blurry for 30 seconds or so. I dont think it matter which eye I use to look through the viewfinder either!

Hmm, my eyes are due to be tested this year.

Maybe Ill try a different opticians this time, as the current ones claim my eyes are fine. Fair enough 0.5 doesnt warrant glasses, but as Ive said the last few times that when I do lots of reading and computer work my left eye goes weird and I get headaches etc, I wouldnt mind having the option of some glasses if theyll help :/

Yup.

Went and got my eyes tested yesterday too and was told again that mine are fine. Theyre at most 0.5 out.

Dioptic wouldnt make much difference as its either eye I think, its just something to do with having one eye open and the other closed :/ My eyes focus fine, it just seems my left one tends to lag behind a little.
