One of the characters in the film suffers from Albinism. Although people with albinism may be considered "legally blind" with a corrected visual acuity of 20/200 or worse, most learn to use their vision in a variety of ways and are able to perform innumerable activities such as reading, riding a bike or fishing. Some have sufficient vision to drive a car.
In India, the stigma still exists that the disabled and poor are repaying the sins from a past life.
About 90 percent of the world's visually impaired live in developing countries, and the reason appears to be an extreme dearth of eye doctors. While India needs about 115,000 optometrists, it has only about 40,000, largely because of regulation issues and a lack of training programs.
Some people in India still believe that blindness is contagious and can be transferred from using the same soap.
Of the 37 million people across the globe who are blind, over 15 million are from India. India is home to the largest blind population in the world. What's worse, 75% of these are cases of avoidable blindness, thanks to the country's acute shortage of optometrists and donated eyes for the treatment of corneal blindness. While India needs 40,000 optometrists, it has only 8,000.
