In a young and otherwise healthy young person with a history of recurrent redness, watering, some discomfort and mild mattering that wears contact lens 95% of the time its the contacts. In many instances the symptoms take week to months to clear up after the contacts are stopped (especially GPC). In the other 5% its often a different problem or a problem like dry eyes that is made much worse or symptomatic by the contacts (much more common in patients older than 25 and female

Having almost same problem here. One time I'm wearing contact lens, enter an air conditioned room and after about an hour my eyes looks tired and red in color. Watery also. As I leave the cold room, my eyes gradually normalizes. It happened to me twice. At air conditioned room, my eyes turns red, watery and looking tired. I then decided not to wear contact lens anymore and back in using eye glasses, but the problem still persisting. Even without using contact lens, my eyes turns pinkish when inside an air conditioned room. Not sure if this I due to dry eyes or other eye problem.
Pataday is for allergy. While I cannot give you an exact diagnosis the most common problem by far is contact lens related problem not dry eye which is extremely rare in a male age 18. Generally it means your contacts are not fitting, you are not wearing them properly or disposing at correct interval or have developed a problem called GPC (giant papillary conjunctivitis).
you will need to work through this with whomever fits your contact lens.
