Özet:

People, unlike most animals are born vulnerable, and they need to be nurtured and raised in a safe environment to thrive and survive. Human development is holistic and complicated. Much of development is dependent on learning through senses such as sight, hearing, touch, taste, and smell. People need all these senses to learn the world around them. Worldwide about 253 million people have visual impairment (VI) problem (WHO, 2018). Depending on the type of visual problem (congenital or adventitious), VI makes life difficult for people infected compared to sighted people. People with VI face challenges such as unemployment, injuries through falling and accidents, low-self-esteem, isolation, depression, and difficulty in mobility within communities.
