Wheat grains: commonly known as pinhole, is an acute purulent inflammation of the sebaceous glands or blepharoplasty glands near the eyelash follicles, with symptoms such as a hard nodule (resembling a lump of flesh) and confined redness, swelling, heat, and pain in the skin of the eyelid. 2. Lacrimal caruncle cyst: Lacrimal caruncle cyst is generally due to the poor secretion of the glands under the lacrimal caruncle tissues, which leads to the accumulation of secretions, resulting in the emergence of cysts, causing bumps at the corners of the eyes. 3.

When a pimple grows in the corner of the right eye, it is recommended to pay attention to eye hygiene, avoid irritation, go to the hospital if necessary, and be treated with the help of a doctor.
