Most eye floaters are caused by age-related changes to the jelly-like substance (vitreous) inside your eyes. As the vitreous becomes more liquid, its microscopic fibers clump together and cast tiny shadows on the retina, which appear as floaters. Several medical conditions can also cause floaters.
The most effective methods of birth control are sterilization by means of vasectomy in males and tubal ligation in females, intrauterine devices (IUDs), and implantable birth control. This is followed by a number of hormone based methods including oral pills, patches, vaginal rings, and injections.
Hormonal contraception refers to birth control methods that contain female hormones. These hormones work on the body's reproductive system to help prevent pregnancy. A hormonal birth control method may contain one hormone (a progestin) or a combination of two hormones (an estrogen and a progestin).
