Entoptic phenomena (from Ancient Greek ἐντός (entós) 'within' and ὀπτικός (optikós) 'visual') are visual effects whose source is within the human eye itself. (Occasionally, these are called entopic phenomena, which is probably a typographical mistake.) In Helmholtz 's words: "Under suitable conditions light falling on the eye ...
Symptoms. Effects of long-term benzodiazepine use may include disinhibition, impaired concentration and memory, depression, [ 19][ 20] as well as sexual dysfunction. [ 6][ 21] The long-term effects of benzodiazepines may differ from the adverse effects seen after acute administration of benzodiazepines. [ 22]
Saccadic masking. Saccadic masking, also known as (visual) saccadic suppression, is the phenomenon in visual perception where the brain selectively blocks visual processing during eye movements in such a way that neither the motion of the eye (and subsequent motion blur of the image) nor the gap in visual perception is noticeable to the viewer.
We've all grown up thinking that sitting too close to the television is damaging to our eyes ... but that might not be the case. Technology spawns lots of confusion ... and a few affectionately ...

You don’t need to run marathons to get benefits: brisk walking, HIIT workouts, dancing, and swimming all count. “Exercise is a total-brain activity,” says neurologist Douglas Scharre, M.D ...
Visual memory describes the relationship between perceptual processing and the encoding, storage and retrieval of the resulting neural representations. Visual memory occurs over a broad time range spanning from eye movements to years in order to visually navigate to a previously visited location. [ 1] Visual memory is a form of memory which ...
