I've been wearing contacts for a few years now and I have never had any problems. But a few months ago I developed a problem in my left eye. Everytime I wear my contact in that one eye, my eye gets really really irratated and red around the colored part of my eye. I got new contacts more than six months ago, and havent had any problems with them or the same solution I have been using up to three months ago. I know I can wear my glasses, but Im just really curious to why this problem has developed and why its this one eye! I don't have allergies and the eye3 never feels irritated, it just gets red. please help!
