What Could Cause Stye? 16 Possible Triggers (List)

Rubbing the Eyes

Rubbing the eyes causes irritation, and bacteria from the hands can transfer to the eyes during contact. Bacteria from rubbing the eyes using hands spread quickly and can cause stye to form. The growth of bacteria around the eyes can spread into different infections and inflammations. A stye is one of the most prominent and common infections to experience in this case. The eye area should be cared for with proper hygiene whenever an itch is present. 

Again, unwanted pathogens and bacteria are transferred through contact while rubbing the eyes. This causes unpredictable outcomes from which styes and inflammations can occur due to the heightened susceptibility to bacterial growth caused by the hands rubbing the eyes.
