I went in January this year to the eye doctor, of course, after researching the shit out of lumpy eyelids, and came away with the seriousness of the situation being none to CANCER.
When I went to the eye doctor, I had my vision and the physical status of my eyes checked out. Everything was fine. The eye doctor felt my lumpy eyelids to see if they hurt, and they didn't. He concluded that these were harmless lumps. They apparently happen when oils and other dust and dirt collect under the eyelid. If you wear contact lenses, then it's more likely to happen. (And I do. I had been wearing them a lot more often than before and cursed my recent obsession with color contact lenses.) So yeah, and it was funny because I kept calling them もの and 小さい玉 (things and little balls), and then I noticed the eye doctor called them 塊 (かたまり), which is katamari, as in KATAMARI DAMACY.
