Dr. Penny Asbell, a leading expert in ophthalmology, examines how environmental factors contribute to ocular surface disease (OSD). Her research highlights the importance of recognizing and managing these challenges to protect eye health and improve the quality of life for those affected by OSD.
Key Environmental Challenges
- Air Pollution: Particulate matter and chemical pollutants cause irritation and inflammation.
- Climate and Weather: Humidity levels and temperature extremes impact tear film stability.
- UV Radiation: Prolonged exposure damages the ocular surface.
- Allergens: Pollen, dust, and seasonal variations worsen OSD symptoms.
- Digital Device Use: Reduced blink rate and blue light exposure contribute to dry eye disease.
Impact on Ocular Surface Disease
- Tear Film Instability: Environmental factors disrupt tear film, leading to evaporation.
- Inflammation: Pollutants and allergens trigger inflammation.
- Epithelial Damage: Chronic exposure leads to ocular surface damage.
Management Strategies
- Environmental Control: Use air purifiers, humidifiers, and protective eyewear.
- Lifestyle Modifications: Reduce screen time and stay hydrated.
- Medical Interventions: Use artificial tears, anti-inflammatory medications, and allergy treatments.
