|The cones in the macular area of the retina are even more densely packed or clumped in the very center, which is called the fovea or the foveal area of the macula. These cone-shaped cells assist us in seeing with our most discrimate viewing, the ability to see detail. For example, features of a person's face, print that we read, the ability to read a map, see our computer screen, and perceive colors are all functions of these cone cells. If these cone cells begin to be affected by an eye condition, such as macular degeneration, this ability to see things most clearly will also be affected. Early in the onset of this type of disease, the person may notice a waviness of lines such as trees, telephone poles, ceiling tiles where the lines become wavy and are broken.|
