What Are Eye Floaters?
Eye floaters are tiny spots, lines, cobwebs, or shadows that seem to move across your vision. They are common and often harmless, especially as we get older. However, if you suddenly notice many new floaters, flashes of light, or a dark curtain over your vision, it could be a warning sign of a more serious eye problem.
Eye floaters are small shapes that appear to move through your field of vision. They can look like:
Tiny black dots
Threads or strings
Cobwebs
Rings
Small shadows
Squiggly lines
They are not usually something on the surface of your eye. Instead, they are often caused by tiny structures or clumps within the vitreous, the clear, gel-like substance inside the eye.
When light enters your eye, these structures can cast shadows onto the retina, making them appear as moving spots or shapes.
Why Do Floaters Happen?
One of the most common reasons for eye floaters is the natural aging process.
As we get older, the vitreous gel inside the eye gradually changes. It can become more liquid and pull away from the retina. This process can cause new floaters to appear.
Floaters can also be associated with:
Nearsightedness
Eye injuries
Inflammation inside the eye
Previous eye surgery
Changes in the vitreous gel
Retinal problems
Most floaters are not dangerous. However, the way they appear can matter.
