Symptoms such as yours are characteristically seen due to something known as floaters
in the vitreous cavity in the eye. These are exactly what they sound like- floating particles in the eye cavity almost like dirt particles in a glass of water. This is commonly due to a degenerative on going process in the eye that happens with age, moderate to high myopia
, any inflammatory process in the eye and is also noticed by patients following a bout of illness or stress
It sounds and seems more startling than it is. There is no real treatment required since it is not vision threatening. The best you can do is try and ignore it. Most people have some floaters and are not so aware of them.
In the rare instance of seeing a shower of red, an increase of floaters or lots of flashing lights, get a retinal exam done but otherwise, you do not need to do anything.
It does not really go away but after a while you stop noticing it . The computer is not aggravating the condition but avoid too much eye strain
and learn to take breaks every hour for a few minutes.
