Am not sure if this is associated with a flu virus which has "floored me" for most of January. Now, I have very sore eyes, and having to use Systane and Omega 7 to relieve the discomfort.
Optician is sending me for an Opthalmology check at hospital, just to check there is nothing else affecting sight.
Sorry to those folks I've been having a dialogue with...I have been avoiding using the PC and Iphone while have been unwell.
