Now, these are not dangerous to your sight but so annoying. Just what you need a cobweb between you and the world around you. Fortunately, they can move but always come back.
I know how annoying they can be, so I looked around and found what information I could and have an article on MCVitamins on what diet can do to get rid of this problem.
It does take work to get rid of them, but intermittent fasting and changing your diet to get the best vitamins that your eyes need, Of course, a better diet and you will feel all around good. Eye Floaters
To Your Health,
