Vitreous Degeneration.
With age, the vitreous gel will liquefy into water and fine sediments which are commonly known as vitreous floaters. When the light passes through, these floaters can be seen as small moving dots or wispy gray spots lines. Vitreous floaters are not dangerous without a retinal tear but can certainly be bothersome. Therefore, the comprehensive eye exam should be performed to see if there is retina hole or tear, which can lead to a retinal detachment.
