Eye health is a key part of a person’s overall health and quality of life.
Whether you live in one of our countries of work across Africa and South Asia, or in a developed country like Canada, we believe everyone, everywhere should have access to quality, affordable eye health care.
Inequity in access to health services – including vision care – is a global problem. It’s connected to a host of other issues, including poverty, gender inequality, inadequate access to clean water and malnutrition.
Loss of sight can have devastating consequences for individuals, families and entire communities, especially in areas and communities that are medically underserved. Vision loss isolates children from their peers and often prevents them from attending or excelling at school. For adults, it can impact a person’s ability to work, care for their family and build social connections.
There is good news: an astonishing 90 percent of vision loss can be prevented or cured.
By partnering with communities, together we are making avoidable blindness a thing of the past.
A cataract is a clouding of the lens of the eye. The lens is located near the front of the eye and it focuses on the retina, at the back of the eye, to form the image we see. A cataract may affect just a small part of the lens, or it may cloud the entire lens. Although not preventable, cataracts are treatable with a straightforward and inexpensive surgical procedure.
Cataracts remain the leading cause of blindness around the world, except for in developed countries such as Canada. Cataracts account for a quarter of all visual impairment, affecting 65 million people.
There are many types of cataracts. Most are caused by a change in the chemical makeup of the lens. Certain medications (such as steroids), genetics, eye injuries or certain diseases can also cause cataracts.
Operation Eyesight was founded in response to the need to treat cataracts, at what is today Arogyavaram Eye Hospital in Sompeta, India. We’ve been working there since 1963 and have made a great impact, thanks to people like you.
Refractive error occurs when the eye cannot clearly focus on images, resulting in blurred vision1. Globally, uncorrected refractive errors (URE) are the main cause of visual impairment2. Uncorrected refractive error can result in lost education and employment opportunities, lower productivity and reduced quality of life.
The four most common refractive errors are:
Refractive errors can be easily corrected. A simple eye examination and a pair of prescription eyeglasses can transform a person’s life. Refractive errors can also be treated with contact lenses or refractive surgery such as laser surgery.
Providing Eyeglasses
We work with local partners in South Asia and Africa to bring diagnosis and optical services to people with refractive error, at little or no cost to them. We establish vision centres at strategic locations within the community, where people can go for an eye exam and be fitted for a pair of custom eyeglasses. Customers who can afford to pay for eyeglasses help offset the cost for those who cannot afford to pay, which allows us to help more people and enables our vision centres to become self-sustaining.
Community outreach and education also play an important role in eliminating uncorrected refractive error. Through door-to-door surveys, school screenings and screening camps, we are able to identify those with vision problems and refer them to the nearest facility for care.
Operation Eyesight is also a proud member of the International Agency for the Prevention of Blindness’s Refractive Error Coalition. This coalition aims to eliminate uncorrected refractive error by the year 2050, ensuring everyone who needs eyeglasses and associated services has sustainable and permanent access, and that they can afford them.
How You Can Help
A $20 donation can help provide a new pair of prescription eyeglasses for at least one person. Please donate today to give the gift of sight to a child, woman or man in need.

Trachoma is a bacterial infection and a leading cause of blindness in areas with shortages of water and crowded living conditions. The bacteria spreads easily through contact with eye discharge from infected people on hands and clothing, and also through direct transmission by flies.
Children are especially susceptible to trachoma; infection often begins during infancy and can become chronic. Left untreated, the eyelid eventually turns inward, causing the eyelashes to rub the eyeball, resulting in intense pain and scarring of the cornea. This leads to irreversible blindness, typically between 30 and 40 years of age.
Because of their close daily contact with children, women are three times more likely than men to suffer the late blinding stage of trachoma, called trichiasis.
According to the International Agency for the Prevention of Blindness, trachoma accounts for about 1% percent of global blindness. It was once endemic around the world, but has disappeared in industrialized nations. It still thrives in many of the poorest areas of Africa, Asia, Central and South America, and parts of the Middle East, wherever people lack access to clean water and proper sanitation.
Operation Eyesight follows the World Health Organization-endorsed SAFE strategy for eliminating trachoma. SAFE is a comprehensive treatment and prevention program that includes:
Properly implemented, the SAFE strategy permanently eliminates trachoma. Because of the emphasis on clean water and sanitation, it also dramatically improves the general health and prosperity of whole communities. Read about how Operation Eyesight is using the SAFE strategy to eliminate trachoma in places like Kenya’s Narok District.
Ocular cancer is a relatively minor cause of blindness but some kinds, like retinoblastoma, can be fatal. In India alone, retinoblastoma accounts for about three percent of all cancers affecting children under the age of five. There are about 5,000 new cases of retinoblastoma reported every year.
Timely treatment of this cancer can save the lives of 95 percent of the children suffering from this disease. In 75 percent of the cases, a child’s vision can be saved. Early screening and treatment are essential.
There are only a few hospitals around the world that specialize in treating the entire range of ophthalmic tumours in both children and adults, and also provide training, research and capacity building. With the help of our generous donors, Operation Eyesight opened one of these world-class facilities in India in 2015.
Diabetes increases the risk factors for a number of eye diseases, and one of them, diabetic retinopathy (DR), is a significant cause of blindness worldwide. Like glaucoma, DR often doesn’t cause irreversible vision loss until its later stages. High blood sugar levels from diabetes eventually damage the blood vessels of the retina.
The World Health Organization (WHO) calls diabetes a global epidemic, and predicts that by 2030, 552 million adults around the world will have either Type 1 or 2 of this disease. The WHO reports almost 35 percent of diabetics currently suffer from some level of retinopathy, and 7 percent of those have their vision threatened.
The International Diabetes Federation says, “While DR is not currently the primary cause of avoidable blindness, it has the capacity to become the leading cause of blindness in the next 20 years and it will affect the poorest people most – already 80 percent of people with diabetes live in low-middle income countries.”
Glaucoma is an eye disease caused by increased pressure within the eye, and it can develop at any age. People with glaucoma usually lose their sight because increased pressure in the eye and other factors (poor blood flow) affect the optic nerve at the back of the eye. The eye slowly loses nerve function and side (peripheral) vision. This occurs painlessly, even unnoticeably.
Although glaucoma can be treated and sight often maintained (if diagnosed in time), an estimated 7 million people are blind because of it, accounting for 2.8 percent of global visual impairment.
Operation Eyesight works with local medical professionals in developing countries to support comprehensive eye care that includes diagnosis and surgical treatment of glaucoma. By constructing facilities, providing equipment and supporting medical personnel at existing facilities, Operation Eyesight helps prevent and treat glaucoma.
There are many other causes of avoidable blindness, including Onchocerciasis (River Blindness), Age-Related Macular Degeneration, and childhood blindness (such as vitamin A deficiency).
These are just a few of the causes of blindness. To see how you can help Operation Eyesight prevent blindness, click here.
