  https://www.ncbi.nlm.nih.gov/books/NBK459349/

  Styes are commonly caused by bacterial infection, most often Staphylococcus aureus, which invades the sebaceous glands of the eyelid. […] Hordeola arise from an acute bacterial infection of the sebaceous glands of the eyelid. Around 90% to 95% of the lesions are due to Staphylococcus aureus, with Staphylococcus epidermidis being the 2nd most common cause. […] The key factors contributing to stye formation include bacterial infection, glandular involvement, and predisposing factors such as inadequate cleaning of the eyelid margins, chronic eyelid conditions like blepharitis, and systemic conditions that may increase susceptibility to stye formation. […] The combination of gland obstruction, whether due to meibomian dysfunction, debris, inflammation, or bacterial colonization, results in acute inflammation of the gland. […] By addressing the underlying causes and predisposing factors, clinicians can effectively prevent styes and manage recurrent cases.

  https://myvision.org/eye-conditions/stye/

  A stye is a red, tender lump that forms around the edge of your eyelid. While sties result from bacterial infections of the oil-secreting glands in the eyelids, you can develop this condition even with optimum eye care. […] A stye, medically known as a hordeolum, is an acute bacterial infection of the eyelid glands. Typically, a stye is a red and painful bump affecting either the upper or the lower eyelid. You will develop a stye when one or more oil-producing glands in your eyelid get blocked and subsequently infected by bacteria. […] The eyelid infection results from thickening and inactivity of the secretions from either oil or sweat glands in the eyelid. Under normal circumstances, the oil from these glands helps to keep the eye moist by preventing rapid evaporation of tears. Increased thickness of the oil makes the glands vulnerable to blockage.

  A stye is a lump on your eyelid caused by a bacterial infection. Improperly sanitized contact lens, eye makeup, and conditions like diabetes and rosacea can increase your risk of a stye. […] Most styes are caused by an infection from Staphylococcus bacteria. These bacteria live on your skin and are normally harmless. […] Sometimes the bacteria can become trapped in a gland or hair follicle, leading to an infection. […] Factors that increase your risk of developing a stye include: not properly cleaning hands before inserting or removing contact lenses, blocked glands due to a buildup of oil, sweat, or makeup, a weakened immune system due to diabetes or other conditions, skin conditions like rosacea and seborrheic dermatitis. […] Sudden or recurring styes can be caused by an overgrowth of bacteria from clogged oil glands. This is known as blepharitis. […] Styes are commonly caused by blocked glands due to a buildup of oil, sweat, or other material. Because of this, not regularly washing your face and hands can increase your risk of a stye. […] Styes develop when a clogged gland or hair follicle on the edge of your eyelid becomes infected.

  A stye is a red, tender lump that forms around the edge of your eyelid. While sties result from bacterial infections of the oil-secreting glands in the eyelids, you can develop this condition even with optimum eye care. […] A stye, medically known as a hordeolum, is an acute bacterial infection of the eyelid glands. Typically, a stye is a red and painful bump affecting either the upper or the lower eyelid. You will develop a stye when one or more oil-producing glands in your eyelid get blocked and subsequently infected by bacteria. […] The eyelid infection results from thickening and inactivity of the secretions from either oil or sweat glands in the eyelid. Under normal circumstances, the oil from these glands helps to keep the eye moist by preventing rapid evaporation of tears. Increased thickness of the oil makes the glands vulnerable to blockage.
