If the bumps on the eyelids are painless to press and the surface is smooth, you may have a lid gland cyst that does not cause discomfort and can be treated with local heat to promote its absorption, or if the lid gland cyst is not absorbed or gradually increases in size, you need to have surgery to remove it. If you have a small bump on the upper eyelid that is painful to press and has redness and swelling around it, you may have a mydriasis, which is an inflammation of the lid gland, and you should first get anti-inflammatory treatment.
