ive been wearing them for 6 years now and have started to have real problems with them since i became pregnant 2 years ago. My eyes seem very dry and become red when wearing them and i also seem to be suffering with headaches. Ive been told that i have a a viral infection but having not worn them for a a few mths ive still not been able to tolerate them.The optician keeps telling me to wean back into them gradually which i have done but but all the blood vessels in my eye statr to flare up and then i have to give them a rest for a wk or two brfore i begin again. Has anyone else experiened this before? Ive started taking vitamins, eating better and getting earliar nights to try and improve the health of my eyes. If i have a late night or have a few drinks my eyes are very red in the morning even when not wearing lenses.
