These are just some of the sort of open-eye distortions, occular tricks and warped depth perceptions that colour long, strange, at times painfully sublime trips down to the Laugh Farm.

The viewer also reduces fish-eye distortion found with regular, non-LCD peepholes.
Slight fish-eye distortion might be introduced as the omnidirectional view image is captured.
Further, several examples are provided which illustrate eye motion distortions in an untracked retinal angiogram, the minimization of these artifacts with eye tracking, and the correction of tracking failures caused by saccades (Subsection 3.2).
This gives it a blurred, muddy, off-putting look, at least when the movie is projected, because blowing up video images amplifies visual artifacts, including eye-gouging distortions like visible scan lines and color that looks as if it's on the verge of separating.
Note the 'fish-eye' type distortions on the atomic columns in the bulk and the 'horse-tail' wispy elongations at the surface.
The metrics and, respectively, PSNR-HVS account for different sensitivity of human eyes to distortions in low and high spatial frequencies similarly to what JPEG standard does by using nonuniform quantization table [11, 14].
Further, eye motion causes distortions and complicates the averaging of multiple B-scans in order to enhance the signal-to-noise ratio (SNR).
Three-dimensional data sets acquired at these fast speeds still show residual motion artifacts, suggesting that increasing OCT speeds alone is not sufficient to overcome head and eye motion induced distortions in densely scanned 3D data sets.
We could also look at the kabbalah, at perfume bottles, at "dust", at glass eyes and eye patches, at the distortions of time.
