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.
