Another more common eye(lid) problem people often give themselves is painful infections on the tip of the eyelids called styes. It's usually caused by someone rubbing their eyes with their hands because it's a double-whammy of cross-contaminating eyes/hands and it embeds surface bacteria into crypts of sebaceous glands.
Also, I heard from a contact wearer another painful accident is forgetting to rinse contacts with sterlie saline after they've been cleaned, that it burns pretty good. Nothing like losing your corneas, but still Pavlovian human monkey training.
Back in my monthlies days, I forgot to rinse on a couple of occasions. My God, the pain is excruciating. There's no waiting it out, and hoping your tears will clear the burning - I had to squirt saline from the bottle directly into my eye to flush it all away.
