What are small specks or spots seen in central vision often referred to as?

The term used for small specks or spots that are often seen in central vision is "floaters." Floaters are tiny clumps of gel or cells that are found in the vitreous humor of the eye and can cast shadows on the retina, which is perceived as spots in one’s field of vision. They are commonly noticed when looking at a plain background, such as a clear sky or a blank wall.

The other options relate to different concepts in psychology and vision. Depth perception refers to the visual ability to perceive the world in three dimensions and judge distances between objects, which is unrelated to the phenomenon of seeing spots. Gestalt principles are theories related to how we perceive and interpret visual stimuli as organized wholes rather than just a collection of individual parts, which does not directly explain the occurrence of floaters. Inherited visual disorders refer to genetic conditions that can affect vision, but they do not specifically describe the visual phenomenon of seeing spots or floaters.
