What causes Blepharitis?
We still don’t know the exact reason why some people are susceptible to blepharitis, but it might be associated with the following:
- Certain skin conditions: Rosacea and Eczema
- Oily skin (both Demodex mites and Staphylococcal bacteria are more likely to grow and thrive)
- Age (more common in older patients)
- Medical conditions, such as Diabetes (possibly because of decline in immune defenses)
- Hormones
- Poor hygiene (not paying attention to washing of eyelids etc., see more below)
- Poorly functioning immune system: Stress, Medical Problems, HIV
- Pollution. This is still under investigation, but there might be a relationship between pollution and blepharitis
