A story of visually impaired (E)
Visual impairment or vision loss is the decreased ability to see things that cannot be fixed by glasses. The common causes of vision impairment are refractive error, cataract, glaucoma, age-related macular degeneration, corneal opacification, diabetic retinopathy, and trachoma. India has a population of 15 million visually impaired people. These people face a challenging task in reading. Even though Braille is the most popular form of reading, 90% of visually impaired people are Braille illiterate. Providing reading materials in the audio format is a challenging task.
