Hello ,
There is a jelly like substance in the eye called Vitrious and as age progresses it starts to liquify and you start seeing floaters or it also happens in high myopes.
Next Steps
You should go to an Ophthalmologist immediately in case if there is increase in number of these floaters, or decreased vision.
Or if you are seeing flashes of light .
Because these are the signs of RETINAL DETACHMENT .
Get retina checked.
Hope this helps , feel free to contact me if you have any further questions or concerns.
Take care
