Pupils are the openings in the center of the iris of the eye that allow light to enter and reach the retina, where visual information is processed. They play a crucial role in regulating the amount of light that enters the eye, adapting to different lighting conditions through constriction and dilation. This ability helps protect the retina from excessive light exposure and enhances visual clarity, making them essential for proper vision and overall eye health.
When light come into your eye your pupils will get smaller. In a dim or dark room your pupils will enlarge to let in more light so you can see. Also some drugs will make your pupils smaller, or when your high they dilate.
I really doubt that there is anyone examining the size of your pupils before allowing you to step onto the ice. If you were ice skating at night, you would have naturally dilated pupils. So yes, you can skate with dilated pupils.
No nothing is wrong with your cat, her pupils are wide because when any object with eyes looks at a bright light, their eyes get small. But when it's dark, the pupils get big. So know you know why. :)
Misshapen pupils in the eye can be caused by conditions such as iris coloboma, aniridia, or trauma. These conditions can lead to abnormalities in the development or structure of the iris, resulting in irregularly shaped pupils. It is important to consult with an eye care professional for proper diagnosis and management.
They do not get smaller, your pupils will dilate / grow larger on E. Takes about 30 minutes or so...
because they smell
It is important to me because I am a mathematics tutor and I would not be able to do my job if I cold not teach my pupils a part of their syllabus.
The correct term depends on the context. "Pupils" refers to multiple students or learners, while "pupils'" is the possessive form, indicating something that belongs to the pupils (e.g., "the pupils' books"). Use "pupils" when referring to the students themselves and "pupils'" when indicating possession.
The opposite of dilated pupils is constricted pupils.
Dilated pupils can be a sign of shock, as they may indicate a response to stress or a lack of oxygen in the brain. In shock, the body activates the sympathetic nervous system, which can lead to pupil dilation. However, dilated pupils can also result from other factors, such as medications, recreational drugs, or certain medical conditions, so it's important to consider the entire clinical picture.
Listing them all would be time-consuming so lets put it this way. Drugs can cause a pupil to change in two ways by dilation making the pupil larger or constricting the pupils. Only two drugs constrict the pupils those being opiates and alcohol. So anything but, these can cause the pupils to dilate.
It is not particularly important, though it is a skill, in manipulating numbers, which school pupils are expected to master.
