A stye or chalazion is a localized eyelid condition that can cause swelling, tenderness, and irritation, often appearing as a small bump along the eyelid.
What Is a Stye vs. a Chalazion?
A stye and a chalazion may appear similar, but they have different underlying causes. Understanding the difference helps guide the most appropriate treatment approach.
A stye is typically an acute infection of an oil gland or eyelash follicle, often causing redness, tenderness, and a noticeable bump that may resemble a small pimple. It can develop quickly and may be painful to the touch.
A chalazion, on the other hand, is usually not an infection but rather a blockage of an oil gland. It tends to develop more gradually and may feel firm but less tender than a stye.
