  • What are eye floaters?

  • They are worms.

  • No.

  • Eye floaters are tiny spots or thread like strands that drift in our field of vision.

  • When we move our eyes and try to look at them directly, they seem to dart away.

  • Yes.

  • I think they try to hide.

  • No.

  • When light from an object enters into our eyes.

  • It passes through the vitreous humor to form an image on the retina.

  • Vitreous humor is a clear gel like substance.

  • It is 99% water and 1% collagen fibers.

  • These collagen fibers are spread evenly throughout the vitreous humor.

  • But sometimes, these fibers tend to come together forming clumps or strands.

  • When we look at a clear sky or a blank page and the clumps or strands are very close to the retina.

  • They cast a strong shadow on the retina, making them easily detectable in the clear background.

  • Thus, forming eye floaters.
