What causes sudden blurred vision in one eye?
Blurry vision also may be a symptom of a detached retina, eye herpes or optic neuritis (inflammation of the optic nerve), among other causes. Certain eye conditions and diseases can cause permanent loss of vision, so it's important to visit your eye care practitioner for diagnosis and prompt treatment. Cataracts.
Eye herpes
Seriously, speaking as someone who recently suffered eye problems (injected in the eyeball and didn't even flinch - just saying) don't waste your time going to your GP. They know fūck all about eyes and will simply tell you to see an opthalmologist. So just try and get an emergency appointment at Vision Express in the Nugent as your first point of call.
