Collagen fiber clusters that are dispersed throughout the vitreous can create microscopic shadows on your retina. Floaters are the shadows you see.

Although they are not always harmful, eye floaters should be taken seriously.
According to the NHS, you shouldn’t be concerned if you have had them for a long time, they are not growing worse, and your vision is unaffected.
If you have undergone cataract surgery or are nearsighted, you are more likely to experience eye floaters.
According to Web MD, “eye disease, eye injury, diabetic retinopathy, crystal-like deposits that form in the vitreous, and eye tumors” can occasionally cause eye floaters, even though they generally pose no significant harm to your vision.

According to the NHS, experiencing “floaters” or flashes for the first time, getting them suddenly, or having more of them than usual is a medical emergency.
Blurred vision, eye pain, floaters following surgery or an eye injury, and a black “curtain” or shadow sliding across your vision are additional indicators of something more serious.
Any of these symptoms could be a sign of serious eye back issues.

The majority of the time, floaters are benign and frequent, but if they start to bother you, physicians advise you to try moving the fluid in your eyes to get rid of them.
You can gaze up and down to do this.
Along with eating a nutritious, well-balanced diet and quitting smoking, taking supplements that promote eye health, such as those that contain omega-3, zinc, vitamin A, and fatty acids, can also assist.
