    Almost 40 years ago, a community service organization started providing eye care in

Gujarat State, in western India.

    The Rotary Club of Navsari operates an eye hospital and 9 area eye centers in and

around Navsari, whose services are for the poorest people. The group opened the hospital,

the Rotary Eye Institute of Navsari, in 1970. Institute officials say India has only about

one ophthalmologist for every 120,000 people. The Institute, however, has ten such

specially trained eye doctors. It has restored or improved the eyesight of thousands of

patients. Many people far from the city. Teams from it travel as far as 150 kilometers to

see patients. People go to their nearest camp, for conditions including glaucoma (青光眼),

night blindness and other problems. Some people are found to have cataracts, abnormal

growths on the eye that can lead to loss of eyesight. India has about 13 million people

with the condition. Cataract patients get free operations to correct the problem.

    Rotary groups also operate eye banks. Doctors at these centers replace damaged eyes

with the healthy eyes of donors who have just died. One such center is the Rotary Rajan

Eye Bank. It operates in cooperation with the Rajan Eye Care Hospital in Chennai. The Eye

Bank opened in 1996. Hundreds of patients have received new corneas from donors since

then. The cornea is the clear front part of the eye that transmits light. 2 million people

in India are blind because of problems of the cornea. The Rotary Rajan Eye Bank holds

continuing eye donation campaigns. It urges people to leave the gift of sight to others

when they die.
