what does it mean if you have black floaters in your eyes?

Most eye floaters are caused by age-related changes that occur as the jelly-like substance (vitreous) inside your eyes becomes more liquid. Microscopic fibers within the vitreous tend to clump and can cast tiny shadows on your retina. The shadows you see are called floaters.

It's unusual for a black eye to develop unexpectedly, when there hasn't been an injury, but a possible explanation is high blood pressure causing a capillary to burst, or one of the conditions listed below.

It may be a symptom of an eye disease (e.g., AMD, cataracts, or glaucoma), or it could be due to issues with the optic nerve or retina. Your eyes need both the optic nerve and retina to see. If your optic nerve is having complications, you might develop optic neuritis, which can make your vision look darker.

Seeing spots or floaters is due to the clumping of proteins in the vitreous, a gel-like substance in the back portion of the eye. This process occurs most commonly as a result of aging, which causes shrinking of the vitreous and aggregation of its proteins.

Vitreous floaters usually occur with posterior vitreous detachment (PVD), and phacoemulsification can increase the risk of PVD. Typically, floaters are a sensation of gray or dark spots moving in the visual field and may persist for months or years 3-5.

Floaters occur when the vitreous, a gel-like substance that fills about 80 percent of the eye and helps it maintain a round shape, slowly shrinks. As the vitreous shrinks, it becomes somewhat stringy, and the strands can cast tiny shadows on the retina. These are floaters.

Floaters in the eyes are also not related to high blood pressure. However, an eye doctor (ophthalmologist) may be able to detect damage to the optic nerve caused by untreated high blood pressure.

A black eye is the appearance of bruising around the eyes. It's usually the result of trauma to the head or face, which causes bleeding beneath the skin. When the small blood vessels, or capillaries, beneath the skin break, blood leaks into the surrounding tissue. This is what causes the discoloration or bruising.

Most of the time, floaters are not the sign of anything dangerous. Floaters caused by loose cells, for example, are usually not that bothersome and often go away on their own in a few weeks or months. The floaters that look like wispy threads tend to be more visible, and in most cases they will also go away with time.

Floaters are tiny specks that can be seen in your field of vision, especially when you look at a light-coloured area such as a blue sky or white wall. They are created when tiny clumps form in the clear, jelly-like substance (the vitreous humour) inside the eyeball.

Many patients with optic neuritis may lose some of their color vision in the affected eye, with colors appearing subtly washed out compared to the other eye. Many others tend to have "floaters" (floating spots) in their vision that are more noticeable in brighter lighting conditions.

Red Flag Symptoms “Flashes, Floaters, Curtains” Floaters are dark specks that float around inside the eye and may disrupt the field of vision. They may appear as spots, circles, cobwebs, clouds, or squiggly lines and are often easier to see while looking at a plain background or white computer screen.

Those little black spots aren't black heads at all. They are actually called sebaceous filaments. ... You see, sebaceous filaments are oil glands that supply your pores with oil. They are a natural part of your skin and they help to keep your skin healthy and nourished.

It has also been discussed that iron deficiency, also commonly known as anemia, can lead to the formation of dark circles around the eyes. With an iron deficiency, the blood is unable to efficiently transport oxygen to your body's tissues, in this case leading to the skin around the eyes, appearing darker as a result.

Dehydration. Dehydration is a common cause of dark circles under your eyes. When your body is not receiving the proper amount of water, the skin beneath your eyes begins to look dull and your eyes look sunken. This is due to their close proximity to the underlying bone.

In the case of eye floaters, they are usually caused by changes to the vitreous - the gel-like substance found within the eye - that tend to occur with age. Spots can be seen when undissolved gel particles and other pieces of debris break loose and float within the liquid centre of your eye.
