What is a symptom of having a Stye?

A stye is often characterized by a red bump, which is typically tender to the touch and appears on the eyelid. This bump results from an infection of the sebaceous gland or hair follicle of an eyelash. The presence of this red bump is a clear indication of the infection, making it one of the primary symptoms of a stye.

While pain in the eye and swelling around the eyelids are also associated with styes, they are not as definitive in identifying the condition as the presence of a red bump. Blurred vision can occur due to various other eye conditions, but it is not a direct symptom of a stye. Thus, identifying the red bump is crucial for recognizing a stye.
