The prevalence of visual impairment is estimated to be around 2.2 billion in the world as per World Health Organization (WHO). Causes of Visual Impairment differs significantly in different regions.

Owing to its negative impact on the individual’s dailies, professional life, productive time, confidence, and self-respect, VI needs to be addressed timely and appropriately. Visual impairments do have profound consequences for the individual, however effective rehabilitation services can restore independence and therefore ameliorate these consequences and restore the individual’s quality of life.
