Dr. chan has diagnosed 8-year-old hsu with myopia (nearsightedness). he recommends that hsu should spend more time playing outside in the sun. why would dr. chan make this recommendation?

Dr. Chan recognizes the strong impact that the environment has on visual genes.

Explanation:

Swapping outdoor activities for indoor studies and play would explain why nine out of ten young people about to leave school in major Asian cities are nearsighted, say the authors of a study published Friday in The Lancet. However, neither genetic factors nor increased activities such as reading and writing should be blamed, the authors suggest, but only lack of sun exposure.

This is because myopia is linked to not only genetic but also environmental factors. The environment greatly influences how our body works and also influences the problem solving that our body presents, Dr. Chan recognizes this and believes that the sun exposure of his myopia patient will help him to overcome this problem.
