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. In fact, we think theyâre as essential as that prescription pad and pen in every doctorâs lab coat pocket.
Safety glasses are made of polycarbonate or CR39 (plastic) or Trivex. Markings on safety glasses: The manufacturer or supplier logo is marked (or etched) on all approved safety lenses, frames (front and temple), removable side shields, and other parts of the glasses, goggles, or helmets. Frames: Safety frames are stronger than street-wear frames and are often heat resistant.
