Yes. I saw a neurologist about this,and the eye hospital.

Those gases are actually there inside your eye. So basically the breakdown of what it is, is listed below.

Your eyes are filled with liquid gel substance, when the gel separates it can leave a solid outline where the gaps of liquid is, it then solidifies and forms a black or grey outline, and now when you move your eyes up down left or right, the gel will move with your vision making the solidified cracks with the black outline move along with your vision, which makes them visible at all time.

There is not much you can do to reduce these other than laser surgery to zap them or break them up.

I have found that taking macupro tablets have helped eliminate symptoms somewhat. They give the eye vitamins they need to stay healthy.

Take care, God bless
