Kennedy, (Cv67). A refractor is an instrument used to prescribe the power of a lens to correct your vision to 20/20 or close to. It can accomodate for astigmatism, near, and distant vision.
The kennedy and her battle group are conducting a composite training unit exercise, (Comptuex), which is an intermediate level exercise designed to forge the strike group into a cohesive fighting team and is a critical step in predeployment training.
