Cataract is a major cause of blindness and visual impairment throughout the world. The most important challenges is to prevent or delay cataract formation. Although safe and effective modern technologies are available that could restore normal vision. Large number of affected cataract patients which continues to increase annually because of the backlog of patients to be operated and the growing number of cataract cases due to increased life expectancy. Even though surgery is the only effective treatment option available, identifying risk factors may help to prevent development of cataract by establish preventive measures and appropriate strategies at the level of primary or primordial level. The World Health Report published in 1998, estimated that there were 19.34 million people who were bilaterally blind (visual acuity <3/60 in the better eye) due to agerelated cataract. In the Andhra Pradesh Eye Disease Study (APEDS) was conducted, it has been reported that cataract alone contributes to 44% of the total blindness in India . Intervention against cataract blindness has received priority attention in the global initiative called VISION 2020: The Right to Sight
Open Access publications, scientists can avoid subscription fees and copyright and licensing restrictions to access free scholarly literature. Since Open Access publishing allows the permanent restoration of scientific data through digital copies, other than the constraint of Internet access, scientists around the world can freely share information and collaborate to enhance the progress of science.Open Access journals not only give royalty to free literature, but also reduce costs for paper-copy production, physical storage, and distribution through digitalized copies.
The benefits of implementing Open Access are reaped by many end users, such as, students, researchers, clinicians, patients, policy makers, and journalists. As long as there is Internet access, people from all over the world, be it an underdeveloped country in Africa, a developing country like India or developed countries such as USA or UK, will have immediate access to latest research findings. Thus, Open Access initiative helps in unlocking the traditional methods of subscription articles and releasing information to tertiary level readers, who normally would not have access to first hand research studies.
