I've Smoked Weed For Two Years. Lately My Eyes Have

I've smoked weed for two years. Lately my eyes have been swelling but I'm not sure if it's a result of smoking weed, especially since I haven't had this issue before. The swelling seems to be the worst when I wake up in the morning. I was sick about a week ago, but my only symptom was coughing, never had a runny or stuffed nose. Haven't really felt Would you have any idea as to why my eyes are swelling?d.
