It can be frightening to see tiny specks of flood your field of vision. Those specks are known as eye floaters and a relatively common phenomenon particularly in older people and those who are near-sighted. They are usually dark in color and may resemble black spots.

What Causes Eye Floaters?
You may be surprised to learn that eye floaters aren’t an optical illusion. When you see dark floaters you’re seeing actual specks of material suspended in the vitreous humor, the jelly-like fluid that fills the interior of the eye. Sometimes these deposits are remnants remaining from when the eye was formed, but more commonly they represent debris that accumulates over time as the eye ages. This debris can move through the vitreous humor casting a shadow on the retina which makes the debris appear as gray or dark specks in the field of vision. Some people with dark floaters also experience jagged lines, specks, or squiggles of light. Dark floaters are so visible, and annoying, because they’re suspended in a liquid media and can move across the retinal field. Read the Full Story from Health Mad
