Adam and his mother visit an ophthalmologist due to vision issues. Adam has myopia, causing difficulty seeing distant objects, while his mother has hyperopia, affecting her ability to see nearby objects. The video explains how a normal eye functions, the causes of myopia and hyperopia, and how these conditions can be corrected using concave and convex lenses, respectively.
