About Floaters - did you understand what your eye doctor said?
Most people have some floaters normally, but they usually do not notice them until they become numerous or more prominent. Looking like cobwebs or squiggly lines or floating bugs, floaters become apparent when you look at something evenly bright, such as white paper or a blue sky, and are more evident when you move your eyes. They are especially noticeable on looking through an optical instrument, such as a microscope or binoculars. They are more common and seem to be more annoying to people who are nearsighted or who have had a cataract operation. What Are These Floating Specks? Much of the interior of the human eyeball is filled with vitreous gel (also called the vitreous), a clear, thick substance that helps in maintaining the eye's round shape. Light passes through the vitreous (after being focused by the cornea and lens) to reach the retina, where images are formed.
Squiggly lines in Vision - Eyes
Floaters, or "squiggly lines", are deposits of various size, shape, consistency, refractive index, and motility within the eye's normally transparent vitreous humor. They may be of embryonic origin or acquired due to degenerative changes of the vitreous humour or retina. The perception of floaters is known as myodesopsia, or less commonly as myiodeopsia, myiodesopsia, or myodeopsia. When observed subjectively, floaters are entoptic phenomena characterized by shadow-like shapes that appear singly or together with several others in one's field of vision. The squiggly lines may appear as spots, threads, or fragments of cobwebs, which float slowly before one's eyes.
