What Triggers Blepharitis and How Can You Prevent It?

Blepharitis is a common but often misunderstood eye condition that causes inflammation of the eyelids, particularly at the base of the eyelashes. It can lead to discomfort, redness, crusting, and even blurred vision if left untreated.

Blepharitis refers to inflammation of the eyelid margins and is usually classified into two types: Anterior blepharitis, which affects the front part of the eyelid near the eyelashes. Posterior blepharitis, which affects the inner edge of the eyelid where it comes into contact with the eyeball and is often related to dysfunction of the meibomian (oil) glands.

Common Triggers of Blepharitis

Bacterial Infections: Overgrowth of bacteria, especially Staphylococcus species, on the eyelids can cause irritation and inflammation.

Meibomian Gland Dysfunction (MGD): These glands produce oils that prevent tears from evaporating too quickly. Blocked or abnormal glands can trigger posterior blepharitis.
