Miosis or myosis, /maɪˈoʊ sɪs/, from Ancient Greek μύειν, mūein, "to close the eyes", is a term with various definitions, which generally include constriction of the pupil.
The opposite condition, mydriasis, is the dilation of the pupil. Anisocoria is the condition of one pupil being more dilated than the other.
Definitions of miosis include:
Light entering the eye strikes three different photoreceptors in the retina: the familiar rods and cones used in image forming and the more newly discovered photosensitive ganglion cells. The ganglion cells give information about ambient light levels, and react sluggishly compared to the rods and cones. Signals from photosensitive ganglion cells have multiple functions including acute suppression of the hormone melatonin, entrainment of the body's circadian rhythms and regulation of the size of the pupil.
She's got good manners
She shivers like a leaf
She drinks some water
She talks about a lot of things
She's got some friends
Which have some friends as well
She sleeps with doors locked
(To) Avoid the things waiting outside
She's got no mirror
She's got contracted eyes
Her biggest wish is a heart
To fake real life
She's got some drugs
She's got some awesome pills
She lost her self–esteem
But nevermind robots don't feel nothing
She's such a goddess
Useful in every way
She stops to drown
When fire's all around
Nevermind the panic
You will get used to it
It's just another bleak place
Forget what you did
She thinks she's pregnant
Which makes her feel alright
And her pony-tail
Will make a good trophy tonight
Chorus ...
Spit at me
You don't need a reason
It's just in case
You never know what comes next
Spit at me
You don't need a reason
