Obstacles to reading can be physical, psychological, environmental, or socio-economic. Physically, visual or auditory impairments like farsightedness or speech impediments can affect reading ability. Psychologically, a lack of self-confidence or negative personality traits in the child can impact reading. Environmentally, poor conditions at home or school around lighting, seating, and ventilation can pose obstacles. Socio-economically, factors like low economic status, commercial influences in media, and government policies can also influence a child's reading achievement.
