Smaller
Smaller. In a scientific research study nasa did in 1998, again in 2008 they found the adrenal glands produce a gas if you will that makes your pupils shrink three times its normal size. If you drink above a 3.98 your pupils will disappear and you will go blind but that is drinking two bottles of vodka lol.
They vary in size depending on the amount of light that the eye is receiving. In bright sunny conditions, the pupil will be small as there is plenty of light impacting on the retina(back of the eye)/. In night time (dark) conditions, the pupil will be large, in order to receive as much light as possible.
You probably mean the pupillary reflex. It is the reflex responsible for your pupils constricting (becoming smaller) when exposed to light and dilating (becoming bigger) when you walk into a dark room.
Heroin relaxes the muscles in your body. The iris is the muscle in your eye that controls the size of your pupil and how much light is let in. When you take heroin it relaxes this muscle making your pupil appear smaller. "uppers" like cocaine will do the opposite.
you can make it look smaller with different types of make up. But the only way to make it smaller is surgery, well that's what I heard. GOOD LUCK! :)
Dilated pupils are bigger, and constrictred pupils are smaller.
Dilated pupils are bigger, and constrictred pupils are smaller.
When it gets dark, your pupils grow big. When the light is on, your pupils grow smaller. Why this answer? Here's a good explanation. It all depends on light and how much of it there is.
Mine get smaller when i lie. you can test this by when your with your girlfriend or boyfriend your pupils usually get big cause you like them. then go stand in the mirror and tell a lie while watching them then you'll know if they get bigger or smaller.
The same as ours do... light constricts (smaller), darkness dilates (larger) the pupil.
No, when your pupils get bigger (dilate), your irises do not get smaller. The iris is the colored part of the eye that controls the size of the pupil. When the pupil dilates, the muscles in the iris relax, allowing the pupil to expand, but the overall size of the iris remains the same.
Owl's pupils get bigger because there pupils react to movement and light causing them to enlarge there pupils.
when its dark your pupils grow because they are trying to look for light for them to see, and when its too light, they get small, trying to minimize the light going through them
When your pupils get smaller (constrict), it allows less light to enter your eyes to avoid overwhelming your retinas with too much light. This helps improve visual acuity by reducing aberrations and increasing the depth of field, making objects appear sharper and clearer.
because when it it is bright like when somebody shines a torch in your eyes your pupils get smaller to stop all the bright light getting in your eyes so it won't damage your eyes and when it is dark like at 12:00 at night and you turn your light off your pupils get bigger to try and find some light it can let in to help you see better in the dark!!!

Ask them if they do or not.
