99% of floater cases are “benign” and are caused by the breakdown of the vitreous, a gel giving the eyeball it’s shape, which can start to become less solid and cells inside the vitreous “float” inside the eyeball. They occur more frequently in individuals who are myopic (nearsighted).
They can be annoying if they move into the field of vision but are not considered to be a medical problem. There is no viable cure in this case. However, if they appear suddenly, it can be related to a medical condition such as a torn retina, so it’s a good idea to see an opthomologist ASAP.
“They occur more frequently in individuals who are myopic (nearsighted).”
That is true as the sharper curvature involved causes a structural strain which results in fragments detaching. I have had floaters all my life; had Rx of -6 and -8 as a child (LASIK corrected a lot of that but doesn’t affect the floaters). I notice that some medications do seem to worsen the floater problem; not sure if it is perception or reality.
