@entity227 is a global problem which is more pronounced in developing countries. There are an estimated 40-45 million blind in the world today, equivalent to a 1% prevalence of @entity1939 . More than 80% of @entity1939 is either preventable or curable by simple techniques, if done in time. Blindness in Southeast Asian countries varies from about .3% in Korea to about 2.0% in bangladesh or Myanmar and 1.5% in India. The causes of @entity227 and @entity1939 include @entity281 such as @entity11738 , @entity130 , @entity3147 (particularly @entity904 deficiency) and @entity154 including muscle imbalance. @entity1939 is common in almost all the developing countries, but it is not problem in @entity3595 Lanka, Myanmar, and Korea. Various control and nutritional measures undertaken by national governments have significantly reduced the prevalence of @entity11738 . It is a serious problem in Bangladesh and some parts of India.

Health education for eye care in the community and primary intervention can control causes like @entity281 , @entity130 , or @entity3147 , while visual aids such as spectacles have to be used for the correction of @entity154 . The problem of @entity227 per se and in @entity1 in particular can be overcome with concerted efforts. The countries affected have initiated control efforts to modify @entity1 's socioeconomic status. Voluntary organizations collaborating with governments have also produced good results. The education of @entity1 about eye health and training of school teachers in early detection of visual problems can be effective.
