Look at things there are small black spots. This is caused by vitreous opacity. The vitreous body is a transparent gel-like tissue, which is clear and bright. The main component is a reticular frame composed of collagen fibers, which is filled with hyaluronic acid, which adsorbs molecules. Cushioned when eyeballs are rotated or shaken.
