World Sight Day 2026: the gift of sight and how to protect it

Every second Thursday of October, the world marks World Sight Day. This year it falls on October 8, and the global call from the International Agency for the Prevention of Blindness is simple: Love Your Eyes.

The numbers behind the day are staggering. The World Health Organization reports that at least 2.2 billion people live with near or distance vision impairment, and for at least 1 billion of them, it could have been prevented or is still waiting to be addressed. The leading causes worldwide are refractive errors and cataracts. In low-income countries, two of three people who need glasses do not have them, and one of two people who need cataract surgery cannot get it.

What the surveys say about Cameroon

Cameroon carries its share of this burden. Community surveys have repeatedly found cataract to be the dominant cause of blindness: 62.1% of blindness in a survey of adults over 40 in Muyuka, in the South West Region, and 55% in an earlier northern Cameroon survey, where glaucoma accounted for 12%, refractive error 9.7%, and trachoma 7.4%. In one South West community study, cataract was the leading diagnosis among people seeking care, yet 93.8% of those cases had not been surgically treated. The World Health Organization lists Cameroon among 20 African countries still requiring intervention against trachoma. No recent national blindness statistic exists for Cameroon, so these survey findings are the clearest picture we have.

Warning signs worth knowing

Cataract shows up as cloudy or foggy vision, like looking through a frosted window, sensitivity to light and glare, poor night vision, colors that look faded, or double vision in one eye. Glaucoma is often silent in its early stages; late signs include tunnel or peripheral vision loss, eye pain, headaches, and halos around lights. In people with diabetes, blurred or wavering vision, dark spots or floaters, and flashes of light can signal eye disease. In children, watch for squinting, sitting very close to screens, headaches after school, or trouble focusing and reading.

What you can do

Get your eyes checked regularly; a simple exam catches the silent conditions. Give every child at least one detailed eye exam between the ages of 3 and 5, since school screenings alone are not enough. If you have diabetes, get a dilated eye exam every year, no matter your age. Keep blood sugar and blood pressure under control, wear sunglasses that block UV in strong sun, and do not smoke. And rush to a hospital for sudden vision changes, a sudden shower of floaters or flashes of light, eye pain, or any eye injury.

Sight is a gift from God, and much of the world’s vision loss did not have to happen. This World Sight Day, we thank Him for the gift of sight and pray for everyone still waiting for care. With gratitude, from all of us at Fada Mission International.
