Hi, you are experiencing floaters in eye, cause of liquifying jelly called vitreous in our eyes. Few people have it and lead normal life, and if there is no disturbance in your vision, like sudden diminution of vision as a curtain falling in front of your eyes or if not associated with flashes of light you can wait and watch. But as you said that it is increasing I would advice you to visit a specialist ophthalmologist and get your eyes evaluated in detail to rule out any problems like a tear or hole in retina.
