These are the most common of the benign functional cysts (functional meaning in response to a normal menstrual cycle). Each time an egg is produced by the ovary a small cyst forms. The cyst is usually very small and ruptures when releasing the egg during ovulation.
Bifocal safety glasses not only protect the doctor (or technician or nurse) and the patient from the spread of infection, but they give the magnification needed to quickly spot the problem and read charts.

The segment line of the executive bifocal lenses provides feedback to the children and ensures that they deliberately use the reading portion of the lens for close work. In contrast, multifocal lenses tend to be misused by children. An additional advantage of the executive design is that the entire lower portion of the lens has the positive power, thereby allowing a greater visual field extant. This can induce peripheral myopic defocus.
