Abstract
Background:
Ayurveda, the ancient Indian system of medicine, emphasizes preventive health care, including the preservation of eyesight, which is vital for social, emotional, and intellectual well-being. Modern lifestyles have contributed to ocular disorders such as diabetic retinopathy and age-related macular degeneration, yet preventive ocular health through Ayurveda remains underexplored.
Materials and Methods:
This review comprehensively studies classical Ayurvedic texts—Charaka Saṃhitā, Suśruta Saṃhitā, Aṣṭāṅga Hṛdaya—and traditional lexicons alongside current scientific research on ocular health. Data were systematically categorized into Āhāra Dravya (dietary substances) and Auṣadha Dravya (medicinal substances), further divided into plant- and animal-origin foods, and herbal and mineral medicines. Special emphasis was placed on Chakṣhuṣya Dravyas (vision-promoting agents) and Ayurvedic ocular therapies.
Results:
Wholesome (pathya) dietary components such as Triphala (Terminalia chebula, Terminalia bellerica, Emblica officinalis), ghee, buttermilk, and milk derivatives demonstrated roles in cleansing ocular channels, balancing doshas, and providing antioxidant and rejuvenative effects. Therapies including Netraprakshalana (eye cleansing), Anjana (collyrium application), Nasya (nasal instillation), and Tarpana (medicated eye bathing), combined with lifestyle modifications like yoga, meditation, and pranayama, were highlighted for their contribution to ocular rejuvenation and disease prevention. Conversely, avoidance of unwholesome foods (excess sour, salty, hot, and alkaline) and detrimental behaviors (stress, excess screen time) was identified as crucial for prevention.
Conclusion:
Ayurvedic preventive ophthalmology offers an integrative, holistic framework for maintaining ocular health, emphasizing diet, therapies, and lifestyle modifications. The consistent use of Chakṣhuṣya Dravyas and adherence to pathya-apathya principles can effectively preserve vision, delay degenerative changes, and enhance quality of life. This ancient wisdom complements modern approaches and warrants further clinical exploration.
