Doctors across India are reporting a sharp rise in cataract cases among people in their 40s and 50s, with diabetes emerging as a major driver behind the shift in what was once considered a largely age-related condition. 

 

Ophthalmologists say persistently high blood sugar is speeding up changes in the eye’s natural lens, triggering earlier onset and faster progression of cataracts.

 

India is home to more than 101 million adults living with diabetes and another 136 million with prediabetes, according to the International Diabetes Federation, with numbers expected to climb further in the coming years. 

 

While diabetic retinopathy is widely recognized as a key eye complication, specialists warn that cataracts are now becoming an equally pressing concern—particularly in patients with long-standing or poorly controlled diabetes. Continuous exposure to elevated blood glucose is believed to accelerate clouding of the lens, reducing vision at a significantly younger age.

 

Cataract, doctors emphasize, can no longer be viewed only as a condition of old age. The growing prevalence of metabolic disorders such as diabetes, obesity and hypertension is pushing the risk curve earlier, making regular eye screening and strict metabolic control increasingly important to prevent avoidable vision loss.

 

“Diabetes is increasingly being recognised as a major contributor to early cataract development,” said Dr Mubashir Parkar Mohammed, Consultant Ophthalmologist, Dr Agarwals Eye Hospital, Vashi - Sector12. 

 

“We are seeing a rising number of patients in their 40s and 50s presenting with cataracts, particularly those with poorly controlled blood sugar levels. These changes in the lens often develop gradually but can significantly affect vision during an individual’s most active and productive years. Regular eye examinations help identify early lens changes and allow timely treatment before vision loss becomes more severe.”

 

Doctors also point to the modern impact of vision loss in working-age adults, where screen-heavy routines—computers, smartphones, video calls and long hours of driving—make even early visual impairment difficult to ignore. Typical symptoms include blurred vision, glare, reduced contrast sensitivity, difficulty reading digital screens and frequent changes in spectacle power.

 

Dr. Agarwal’s Eye Hospital has announced free cataract eye evaluations for the general public until 15 July 2026, with registrations available via 95945 86999.

 

“Despite rising awareness, misconceptions around cataract treatment continue to delay timely intervention,” said Dr Mubashir Parkar Mohammed. 

 

“Many patients still believe that surgery should only be performed once the cataract has ‘matured’, or assume that vision loss is a normal part of ageing. Some also expect eye drops to reverse the condition, which is not medically accurate. Such delays can lead to advanced cataracts that are more difficult to manage surgically and may affect visual recovery outcomes.”

 

Experts urge people above 40—especially those with diabetes or other metabolic conditions—to undergo regular comprehensive eye examinations. They stress that early detection, timely surgery when needed, and better control of underlying health conditions remain key to preventing long-term vision damage.
