Refractive disorders are very common in children. Disorders like farsightedness, shortsightedness, and astigmatic affect millions of children globally. Unfortunately, in most children, vision disorders often go undetected for many years. This often leads to poor academic performance and more important, the child is unable to participate in social and sporting activities. Further, if a condition like a lazy eye (amblyopia) is left untreated, it leads to permanent blindness. This leads to lack of job opportunities, difficulty driving, and a poor quality of life. Even when teachers note difficulties in vision in children, they are often powerless to do anything about it.
For a long time, one major obstacle in eye testing was the lack of a suitable machine. Most of the traditional eye screening machines are large, cumbersome, lack portability and often induce panic/fear in children.
