Low vision is often misunderstood as an inevitable part of ageing, something that must simply be accepted. However, ophthalmologists stress that while not all vision loss can be prevented, much of it can be slowed,
managed, and in some cases significantly controlled with timely intervention and conscious lifestyle choices.
According to Dr. Purendra Bhasin, Founder & Director, Ratan Jyoti Netralaya, Gwalior, low vision cannot always be completely prevented, especially when linked to genetic conditions or age-related eye diseases. However, its progression can frequently be slowed with early detection and appropriate care.
“Regular eye check-ups are essential for early detection of conditions such as glaucoma, diabetic retinopathy, and macular degeneration,” explains Dr Bhasin. In many of these diseases, damage occurs gradually and often silently. Early diagnosis, followed by timely treatment, can help preserve remaining vision and limit further deterioration.
Echoing this, Dr Sharoon Shitole, Consultant Ophthalmologist & Managing Director, Vencer Hospital, Pune, cautions against dismissing vision changes as simply age-related. “We often treat low vision as part of the normal ageing process,” he says. “But one of the easiest yet most effective measures is to get your eyes tested regularly, even if you think you see well.”
He highlights glaucoma as a classic example, a condition that can damage the optic nerve without pain or obvious early symptoms. By the time vision changes become noticeable, significant damage may already have occurred. For this reason, Dr. Shitole strongly recommends routine eye examinations after the age of 40, particularly for individuals with diabetes, hypertension, myopia, prolonged screen exposure, or a family history of glaucoma.
Beyond clinical screening, both experts emphasise the power of daily habits in protecting long-term vision.
Dr Bhasin notes that managing chronic conditions such as diabetes and high blood pressure is crucial, as both can directly impact the health of retinal blood vessels. He also advises reducing prolonged screen exposure, ensuring proper lighting while reading, and wearing UV-protective sunglasses outdoors to minimise cumulative eye damage.
Nutrition also plays a meaningful role. A diet rich in antioxidants, omega-3 fatty acids, and essential vitamins can support retinal health and may help slow degenerative changes. Leafy greens, fatty fish, nuts, and colourful fruits contribute protective nutrients that strengthen ocular tissues over time.
Dr Shitole adds that seemingly minor symptoms should never be ignored. Dry eye and digital eye strain, for instance, are increasingly common in today’s screen-heavy lifestyles. Burning sensations, grittiness, excessive watering, fluctuating vision, or persistent eye fatigue are early warning signs that the eyes require attention.
He advises simple but effective “screen hygiene” practices: blinking consciously, taking regular breaks using the 20-20-20 rule (looking 20 feet away for 20 seconds every 20 minutes), and avoiding excessive exposure to harsh screens. Protective eyewear during sports or hazardous activities and sunglasses that block ultraviolet radiation outdoors are also essential preventive measures.
Importantly, gradual changes in vision, blurred reading, difficulty seeing at night, increased glare sensitivity, or frequent eye strain, should not be dismissed as normal ageing. Early medical consultation can make a significant difference.
Even when vision loss cannot be fully reversed, interventions such as vision rehabilitation and low-vision aids can help individuals maintain independence and preserve quality of life. Modern assistive tools, magnification devices, and adaptive techniques enable patients to continue daily activities with confidence.
The message from both specialists is clear: while low vision may not always be entirely preventable, it is rarely helpless. Regular screening, disciplined lifestyle habits, and timely medical care form the foundation of preserving sight for as long as possible.
Vision, after all, does not fade overnight and neither should vigilance.
