The optometry van in the mountains: a ledger of 5,000 pairs of glasses

A converted van drives into the playground of a mountain primary school; a side panel flips up, and there is a small optometry room.

This is the "Bright Sight" optometry van, and the man who runs it is Old Ke, formerly the owner of an eyewear shop in the county seat. The idea came from a trip into the countryside to fit glasses: a mountain child, six hundred degrees myopic, had never owned a pair. "He couldn't see the blackboard in class. His family didn't know. The school didn't know. He thought the whole world saw everything as blurry as he did."

Old Ke went home and ran the numbers: one van, one set of equipment, fuel for mountain roads — that much he could shoulder himself. But for a project to last, it needed a ledger. The ledger rules he set down were later praised by friends in the charity world:

• Glasses are free, but the exam must be scientific — the same procedure and standard as his shop; no glasses for pseudomyopia, intervention first.
• Registration and records — a file for every child's prescription, rechecked every six months, changes tracked.
• Open books — the cost of every pair of glasses, the flow of every donation, published down to the last cent.

In the first year the van covered twenty village schools and fitted eight hundred pairs. The children's reactions were all their own. Some, putting on glasses, said their first words: "So that's what the writing on the blackboard looks like." Some stared at themselves in the mirror for a long time, then smiled shyly. One girl, after being fitted, handed Old Ke her old pair of "makeshift glasses" — two pieces of cardboard with holes punched in them — and said, "You can keep this one. For kids who can't afford it."

Old Ke accepted the cardboard glasses. Today they sit in the most prominent spot in his office.

Run a charity long enough, and the real danger isn't running out of money — it's moving yourself. Old Ke's ledger philosophy: every pair of glasses must be fitted scientifically, worn steadily, followed up fully. Emotion lasts a moment; a child's eyesight lasts a lifetime.

By the project's fifth year, the van had covered sixty-two schools, fitted five thousand pairs, and built files on more than ten thousand children. Behind the ledger's numbers runs a string of stories: one child leapt from two hundredth in the grade to fiftieth after getting glasses; one child's exam revealed a congenital eye disease rather than myopia, and the van connected the family directly with a hospital, where the child had surgery; one school, using the van's data, rebuilt all its classroom lighting.

Where does the money come from? Old Ke's ledger grows thicker and its sources more mixed: part is subsidized by the profits of his eyewear shop, part comes as directed donations from old customers, part from charitable foundations — and part is the children's "return gifts." One student who got glasses and then tested into university donates ten yuan to the program every month, from freshman year to this day. "Ten yuan isn't much," Old Ke says, "but I book every installment as principal. They are coming back to invest in the child they used to be."

There are two vans now, and Old Ke is sixty. His retirement plan is written on the flyleaf of the notebook: "Hand the ledger to the younger generation. The schools I can no longer reach, let them keep driving." On the ledger's last page, he has written one line by hand:

"Glasses have prescriptions. Seeing should have no threshold."
