The State of Preventative Blindness in India

The State of Preventable Blindness in India

Home DrishtiBution The State of Preventative Blindness in India

Where we’ve made progress, and where we’re still falling behind.

A World-First Effort, But Not the Finish Line

In 1976, India became the first country in the world to launch a publicly funded national program to reduce blindness. The Cataract Blindness Control Project, later supported by the World Ban, was a game-changer, pushing blindness prevention into national health policy for the first time.

Fast forward to 2019, and the results were clear:
India’s blindness rate dropped from 1% to 0.36% (National Blindness and Visual Impairment Survey, 2019).

But in a nation of over 1.4 billion, this still leaves millions struggling with vision loss – much of it preventable.

Visual Snapshot: What “Blindness” Means

According to India’s National Programme for Control of Blindness (NPCB), blindness is defined as:

Inability to count fingers from 3 meters
Vision of 6/60 or worse in the better eye (even with best correction)
Field of vision reduced to 20 feet or less

Visual impairment includes uncorrected refractive error, cataract, glaucoma, diabetic retinopathy, trauma, and nutritional blindness.

Who’s Most Affected?

1. The Rural and Urban Poor

Over 70% of India’s population lives in rural areas (Census 2011), but rural eye care is scarce.
In rural regions, there’s only 1 ophthalmologist per 250,000 people (Vision 2020 India).
Urban poor also face long wait times, unaffordable care, and disability-linked unemployment.

In our DrishtiBution medical camps, we see this every year: villagers who’ve gone blind without ever seeing a specialist.

2. Children

India is home to over 320,000 blind children under age 16 (Murthy et al., 2008).
The main causes:
- Vitamin A Deficiency (VAD)
- Corneal scarring
- Measles, trauma, and congenital cataract

Even today, VAD affects 20–30% of children in parts of North East India (Bhattacharjee et al., 2008), especially in food-insecure, low-literacy communities.

“If left untreated in childhood, vision loss becomes permanent because the brain stops developing visual pathways.”
– Shaurya Sharma, Ophthalmologist

3. Women

Women in India are 50% less likely than men to access cataract surgery or eye exams (NPCB, 2018).
Barriers include:

Lack of mobility
Poor road conditions
Misconceptions about surgery
Low household decision-making power

Community screenings, women-led awareness drives, and female-friendly clinics are key to improving access.

J.S. Trust’s mobile eye camps actively target women and girls in low-income neighborhoods, because access starts with outreach.

4. People with Pre-Existing Conditions

11 million Indians currently have glaucoma; 24 million are at risk (IAPB India).
30%+ of diabetics over age 40 show signs of diabetic retinopathy (NIH India, 2022).
Many patients remain undiagnosed due to lack of routine screening protocols and limited public awareness.

What Preventable Blindness Actually Looks Like

Cause	Preventable?	Treatment
Cataract	✅	Surgery (99%+ success rate)
Refractive Error	✅	Spectacles
Diabetic Retinopathy	✅ (if caught early)	Laser, medication
Glaucoma	❌ (damage irreversible)	Early diagnosis + lifelong control
VAD (Vitamin A Deficiency)	✅	Diet + supplementation
Eye Trauma	✅	Education + protective equipment
