I have had allergies all my life. When I was 5 I had an allergic reaction to ragweed and the whites of my eyes swelled up and covered my pupil so I couldn't see for a couple of days. This happened again when I was nine. I am now 21 and thankfully it hasn't happened since then but I do have a lot of problems with my eyes. On days when things are really bad my eyes get all goopy and it get harder to focus. When I told my doctor about it he prescribed an allergy eyedrop called Patanol that helps. Sometimes it burns a little at first but it usually helps to dry my eyes up when they are super itchy and watery. I don't know if that will help you at all since you have contacts. But I also keep eyedrops , just over the counter ones, for when my eyes burn because they are too dry. Also I have found that if I wear my glasses or sunglasses outside that helps keep airborn allergens from getting into my eyes. Hope this helps some.
