Netra Raksha: Safeguarding vision through Ayurvedic wisdom

Abstract

The eye is a vital sense organ, enabling perception and interaction with the external world. In today’s digital age, excessive screen time, poor lifestyle choices, and environmental stressors significantly impact ocular health. Ayurveda, the ancient Indian system of medicine, provides holistic approaches to maintain and enhance eye health through preventive, promotive, and therapeutic strategies. This review integrates classical Ayurvedic texts with contemporary understanding of eye strain and digital vision syndrome. The principles of Dinacharya (daily routine), Ritucharya (seasonal regimen), dietary guidance, and herbal formulations were examined in relation to their role in maintaining ocular health. Key Ayurvedic interventions like Anjana (collyrium), Tarpana (retention of medicated ghee over the eyes), Netra Prakshalana (eye wash), and internal medicines such as Triphala were correlated with modern preventive strategies for eye care. Findings suggest that Ayurvedic practices effectively address common eye disorders including dryness, fatigue, and diminished vision. Herbs like Triphala, Yashtimadhu, and Amalaki are rich in antioxidants and have shown ocular benefits. Techniques like Trataka (yogic gazing) and Netra Vyayama (eye exercises) support muscular endurance and focus, mitigating the effects of prolonged digital exposure. Integrating Ayurvedic eye care with modern lifestyle modifications presents a sustainable approach for preserving visual health. Ayurvedic regimens are not only preventive but also rejuvenative, aiming to maintain Ojas and enhance the longevity of vision. Further clinical studies can strengthen the scientific basis of these practices and facilitate their wider adoption.
