Why do we need the cornea and the lens, if both serve to refract light ? A) because refraction is only effective when light travels between media of equal density, such as the aqueous and vitreous humors B) Because light must be bent twice in order to flip the image C) While the cornea has greater refractive power, the lens can adjust the degree of secondary refraction according to where objects appear relative to the viewer D) While the lens...
