6. Netra-Shakti-Vikasaka (Improving the Eye-sight)
Posture: Stand with your feet close together, keeping your back straight and your head tilted back as far as possible. 
Exercise: Focus intently on the spot between your brows, keeping your gaze fixed without blinking. This will require squinting. If your eyes begin to feel strained or start watering, pause the exercise and resume after a short break. Begin with five minutes initially.
This practice stimulates the nasociliary plexus of the autonomic nervous system and engages the nerve fibers responsible for moving the eyeball and its internal structures. It enhances the power, balance, and coordination of the muscles controlling eye movement. Additionally, it strengthens the iris muscles, which act as a diaphragm to regulate the amount of light entering the eye and reaching the retina.
Focusing on a single point also activates the muscles surrounding the eye’s lens. Their contraction and relaxation adjust the lens shape, optimizing light focus on the retina for creating sharp images. Through this exercise, the neuro-muscular system of the eyes is improved for greater performance and resilience.
Beyond its immediate benefits for enhancing eye function, this exercise provides a significant advantage in sharpening mental concentration techniques, making it a valuable practice both physically and mentally.
Introduction
Yoga is a holistic discipline that aims to harmonize the body, mind, and senses. Among the many subtle practices of yoga, Sukshma Vyayama (subtle yogic exercises) plays a crucial role in preparing the body and mind for deeper practices such as asana, pranayama, and meditation. These exercises are gentle, accessible, and highly effective in improving physiological and neurological functioning.
In the modern era, the excessive use of digital devices such as computers, smartphones, and televisions has led to increased strain on the eyes. Problems like eye fatigue, dryness, blurred vision, and headaches have become common. Therefore, maintaining eye health is essential for overall well-being.
Netra-Shakti-Vikasaka is a specialized Sukshma Vyayama practice designed to strengthen the eyes, improve vision, enhance coordination, and reduce visual fatigue. It involves systematic eye movements, relaxation techniques, breath awareness, and concentration practices that stimulate the visual system and promote ocular health.
This practice is particularly beneficial for students, office workers, and anyone exposed to prolonged screen time, as well as for individuals seeking to improve concentration and mental clarity.
Netra-Shakti-Vikasaka is an essential Sukshma Vyayama practice that enhances eye strength, improves vision, and promotes overall visual health. In today’s digital age, it serves as a powerful tool to counteract the harmful effects of prolonged screen exposure.
By combining eye movements, breath awareness, and relaxation, this practice not only improves ocular function but also enhances mental clarity and concentration. Regular practice leads to better vision, reduced fatigue, and improved quality of life.
Ultimately, it contributes to the broader goal of yoga—harmonizing the body, mind, and senses for optimal health and inner awareness.
