Blepharitis is a catchall term that means “eyelid inflammation.” There are many causes of blepharitis, such as rosacea and sensitivity to environmental irritants. For most people, blepharitis is a self-limited condition that causes episodic eyelid irritation. Most people complain of red, watery eyes with a sandy or gritty sensation. The eyelids may look red and many people notice their eyelashes falling out. Treatment involves lid scrubs, warm compresses, and antibiotic/steroid medications to cool the eyes down. While not truly an infection or a “disease,” blepharitis can be somewhat chronic and very annoying. The key is to find a combination of lid hygiene and medical treatment that keeps the eyes comfortable on a long-term basis.
