I dont have an answer about which med could be causing your symptoms, but I know that for me, allergy season is rampant right now. I use Baby Shampoo diluted in warm water, and using a cotton ball, wash my eye lids gently many times a day (and EVERY time I come in from outside). This is soothing, and safe. (My opthamologist told me this is also used for people with dry eyes). Might help you til you figure out if it is one of your meds. I would suggest an appt. with an opthamologist to be sure its not an eye disorder called (I cannot spell it correctly but it sounds just like) "bluffer-itis".
