Not sure what it is but it's been going on 7 hours now since I woke up. I've washed my eye thoroughly, applied lubricating drops and checked for any visible signs of anything but it all looks normal. It's definitely the eye as opposed to the eyelid as I when I touch the eye itself (the pupil bit) its very sore compared to the other one.
I don't wear contacts and can't think of anything I've done to have caused an injury.
I assume this isn't for A&E but very worried obviously as its my eye! Any ideas?
