Protein strings (floaters)Protein strings, which can be found floating in the liquid inside the eyeball, can be seen when looking at bright point-light sources.
Protein strings tend to remain motionless if the eyes are still, rotating vertically if one looks up and down rapidly, and horizontally if one looks right to left rapidly. In either case these slow down and stop after a few seconds. The motion of waking-consciousness CEV noise cannot be controlled so actively.
Corneal liquid
CEV does not involve the liquid and air bubbles on the surface of the cornea, which can also be seen by extremely nearsighted people when looking at bright point-light sources with glasses/contacts removed. Half-closing and reopening the eyelids creates a very definite wiper-ridge in the corneal liquid that is readily visible. Fully closing and reopening the eyelids also stirs up the corneal liquid which settles down after a brief moment. The motion of waking-consciousness CEV noise is not so directly and physically controllable and repeatable. This is not necessarily only associated with extreme nearsightedness.
