your eyes go almost completely black, like shark eyes but you'll barely be able to see the colored part of your eye. and i mean barely. it also depends on the person though. mine got extremely dilated.
If taken orally, the drug will just dilate your pupils very much. If taken through the nostril in a crushed form, it may cause your eyes to water, redden, and will dilate them even more because the ecstasy hits the bloodstream near your eyes quicker this way.
That the photoreceptor's in your eyes may be weak. or that you have concussion are unconscious or drugged or that there is not much light
Pupils dilate when there's not enough light in the room or area you're in. They dilate to let in as much light as possible so you can see as well as you can in the dark. When outside and it's bright, your pupils get smaller because there is too much light. ~ ~Imadork881 changed to Sleenky ^.^
Pupils dilate to allow more light to fall of the back of the retina. Pupils typically dilate in low light conditions, during states of sympathetic nervous system stimulation, and in response to a number of nervous system stimulant drugs and hallucinogenic drugs.
I'm not sure exactly why, but your pupils dilate for some scientific reasoning having to do with your brain and what you find attractive, something like that. However this only happens for like a split second, and then the eyes go back to normal.
Yes it can - Caffeine is a stimulant and causes a release of adrenaline. Adrenaline is the hormone which prepares us for 'fight or flight' in stressful situations and it has a number of effects on the body.

The pupil is the innermost circle in the eye. It should always be black, regardless of the person's eye color. The pupils can increase or decrease in size depending on how much light. Pupils can also change in response to the effects of medications or street drugs.Here are two videos. In the first, a doctor explains why drops dilate the pupils for eye exams. In the second, you can see a close-up of someone shining light onto a person's pupils and removing the light.
Much like the aperture on a camera the pupils dilate to allow more light to fall onto the optical receptors. In bright settings there is less need for light and pupils constrict.
Certain drugs can cause your eyes to dilate or constrict but barring that it is mostly a function of regulating how much light is entering the eye. If you want to undilate your eye, be in brighter light.Also check out this web site. It might help you out some.http://www.wikihow.com/Dilate-or-Shrink-Your-Pupils-on-Command
Your pupils dilate. Your nervous system is in control of your pupils it affects the cranial nerve called the ocular nerve which causes it to not respond to light hence the dilation.
