Can fiberglass floaters be straightened

A procedure called laser vitreolysis uses a focused laser to break apart floater clumps inside the eye. The evidence on effectiveness is mixed. Cannon holds a BS in Biology and Psychology from Indiana University. He received his Doctorate in Optometry from Indiana University School of Optometry, where he earned the Dean's Scholar award and participated in years of ophthalmic research. Floaters in eyes are spots that move through the field of vision. Eye floaters may appear grey or black, cobweb like or stringy and they may. Most eye floaters can't be eliminated instantly, but they typically become less noticeable over time as your brain learns to ignore them. For the minority of people with severe, vision-disrupting floaters, laser treatment and surgery are options, though both carry real tradeoffs.
