VOA标准英语2010年-NGO Provides Low Cost Eye Care in Nort

（单词翻译）

A non governmental organization in Nigeria called Sightsavers is working to help restore sight to visually impaired¹ people. The Federal Ministry² of Health recently conducted a survey on visual Impairment. It found that about 1,130,000 people in Nigeria are blind. More than a third of them are in the northwestern states.

Umar lives in the Ungwar Sanusi section of Kaduna town. He has had cataracts⁴ in both eyes for many years, but only recently started coming to the clinic. "After the treatment," he says, "I started seeing clearly. And I am happy that my sight has been restored."Umar is not alone.

They're treated here or in clinics supported by Sightsavers in several states, including Cross River, Kaduna, Kwara, Sokoto and Zamfara.
Sightsavers covers almost all the costs, says Ahmed Danbaba, one of the nurses:
"They provide the drugs, the surgical⁵ instruments, even the operating microscopes ... If not for that, I think the cost of cataract surgery would not be affordable⁶."Sightsavers has been working to prevent, reduce, as well as cure blindness for more than 60 years. It also promotes equal opportunity in the workplace for people with visual disabilities. The NGO works with the ministries⁷ of health and its eye centers, especially in the northwest.
The NGO makes eye treatment available at a fraction of the cost of privately⁸ owned centers. In these clinics, cataract surgery costs about $170, or N25,000, but the same service is provided at eye centers supported by Sightsavers for $13, about N2,000.

Sightsavers has trained 31 ophthalmologists in five Nigerian states.
Cataracts, which can cause blindness, are caused by a build-up of proteins that cloud the lens – the part of the eye that focuses light and produces clear, sharp images.
Cataracts can be caused by many factors, including ageing, smoking, diabetes⁹ and dehydration¹⁰ caused by heat and cholera¹¹.
Doctors say the local custom of withholding¹² water from women during labor¹³ and immediately after giving birth can also contribute to getting cataracts.
The country director for Sightsavers in Nigeria, Sunday Isiyaku, says simple measures like improving hygiene¹⁴ can help prevent cataracts and other diseases, such as trachoma -- a bacterial¹⁵ infection of the eye. Symptoms include discharge from the eye, blurred¹⁶ vision and swollen¹⁷ eyelids¹⁸. Isiyaku says 80% of blindness is preventable and trachoma can be reduced largely with good hygiene, such as washing one's face, and keeping one's environment clean.
Sightsavers is working to expand its campaign for better eye care.
