Quizplus · Accepted Answer

The fovea is the area of the retina that contains the highest concentration of cone cells, which are responsible for color vision and visual acuity. When looking directly at an object, the fovea is responsible for the clearest and sharpest vision. Therefore, Melody will most likely be able to read the phone number if she looks directly at it with her fovea, where the cones will be able to distinguish the tiny details of the print.
