Cause #4: Chalazion
In cases when a gland that produces oily substances in the eyelid becomes obstructed, chalazia (plural of chalazion) develop. Even though it looks very similar to a stye, it is not the same thing. A stye is a local infection of a sebaceous gland of the eyelids that can be painful and tender.
Conversely, a chalazion is usually painless and it is the result of an obstructed sebaceous gland. However, in chalazia, there is inflammation without infection. Furthermore, a chalazion tends to recur every now and then. They also can grow big in size.
