If im seeing a floater in my left eye and im looking at something white or a very light color?

I can see the floater in my left eye very clearly. The floater is like a little black dot and follows every direction im looking at especially reading. Im only 26 is that normal for this age? If im seeing this little floater in my left eye, does that means this is my left eye is dominant.If im seeing a floater in my left eye and im looking at something white or a very light color?
Floaters are little pieces of cell debris or protein that float in front of your retina in your vitreous humour (the jelly inside your eye). Eventually your floater will either break down, float away, or your brain will learn to ignore it. Floaters are normal in everyone - they occur more in very near sighted people. Usually your dominant eye is the eye you would choose to keep open when focusing on something, like if you were looking through a sight of a gun or shooting an arrow. You can make a small triangle with your hands, outstretched arms - put an object in the center of the triangle with both eyes open. Close one eye at a time - the eye that still has the object in the triangle is your dominant eye.If im seeing a floater in my left eye and im looking at something white or a very light color?
I don`t know about calcium or protein deposit in the eye,I have this floaters in my eyes since six years old.Doctors and could not explain what is inside my eye,until recently I took some health supplement for this floaters they seems to lees of it in my eyes.By the way now I am 53 years old.
Floaters are small calcium deposits and are fairly normal. I have several and my eye doc isn't concerned about them.
