Some examples of entoptical effects include: Floaters depiction Purkinje tree depiction Floaters or muscae volitantes are slowly drifting blobs of varying size, shape, and transparency, which are particularly noticeable when viewing a bright, featureless background (such as the sky) or a point source of diffuse light very close to the eye.
Oculocardiac reflex can be profound during eye examination for retinopathy of prematurity. [5] However, this reflex may also occur with adults. Bradycardia, junctional rhythm and asystole, all of which may be life-threatening, [6] can be induced through this reflex. This reflex has been seen to occur during many pan facial trauma surgeries due ...
It switched the images presented to each eye to distort depth perception. A pseudoscope is a binocular optical instrument that reverses depth perception. It is used to study human stereoscopic perception. Objects viewed through it appear inside out, for example: a box on a floor would appear as a box-shaped hole in the floor.
The Pulfrich effect is the effect that covering one eye with transparent but darkened glass can cause purely lateral motion to appear to have a depth component even though in reality it doesn't; even a completely flat scene such as one shown on a television screen can appear to exhibit some three-dimensional motion, but this is an illusion ...
For example, when red and blue are viewed side by side on a dark surrounding, most people will view the red as "floating" in front of the blue. However, this is not true for everyone, as some people see the opposite and others no effect at all. This is the same effect that both Goethe and De Wilde had indicated in their observations.

If your whole eye has gone red, learn about the causes of bloodshot eyes and how to fix them. Weirdly enough, a red spot on eye might have a cause totally unrelated to your eyes: sneezing or coughing.
The globe of the eye, or bulbus oculi, is the frontmost sensory organ of the human ocular system, going from the cornea at the front, to the anterior part of the optic nerve at the back. More simply, the eyeball itself, as well as the ganglion cells in the retina that eventually transmit visual signals through the optic nerve. [ 1 ]
The human eye is a sensory organ in the visual system that reacts to visible light allowing eyesight. Other functions include maintaining the circadian rhythm, and keeping balance. Arizona Eye Model. "A" is accommodation in diopters. The eye can be considered as a living optical device.
