It typically takes around 5-10 seconds for your pupils to adjust to a change in light. This process is controlled by the iris, which can expand or contract to regulate the amount of light entering the eye.

Just divide the speed of light by the distance.
About 8 minutes
Well, it takes 2,700 years for light to travel that far. Anything travelling at half light-speed would take 5,400 years. At 1/4 light-speed, it would take 10,800 years.
Alpha Centauri is 4.37 light-years away from Earth, which means it takes light, the fastest thing in the universe, 4.37 years to travel that distance. Although light travels at a speed of about 186,282 miles per second, the vastness of space makes this journey take years.
The pupils get larger. Pupils take in light and if it is dark, there is not much light if there is any at all. The pupils grow larger to take in as much light as possible. If the hole is bigger, more light can come in faster.
They do not get smaller, your pupils will dilate / grow larger on E. Takes about 30 minutes or so...
The eye can take around 5-10 minutes to fully adjust from darkness to light. During this time, the pupils will constrict to reduce the amount of light entering the eye, allowing the photoreceptor cells to gradually adapt to the increased light levels.
The pupil gets smaller but when light is taken away, the pupils dilate (get bigger) to increase the ability to take in light. Many people come out of dark areas and there pupils are still enlarged
It typically takes about 20-30 minutes for your eyes to fully adjust to the dark. During this time, your pupils dilate to let in more light, allowing you to see better in low-light conditions.
Pupils don't dilate from light, the constrict. They dilate in the dark, to take in more light, and constrict in the light so your eyes don't get damaged. Hallucinogenics, stimulants and alcohol and make your pupils dilate and opiates and diazepam can make them constrict. Im not sure what that's called though..
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.
The reason behind why your pupils dilate is because they need to receive more light from their surroundings when it is dark, enabling you to see better. They expand and take in more light, allowing you to see. They contract again when exposed to a lot of light. You can test this by having someone close their eyes and when they open you can have them look directly at a light and you can see their pupils shrink if you look closely.
I take Prozac for the last month and when I started feeling the drug about a week ago my pupils are very dilated after I take it.

i take zeroquel xr and it does make you a lil tired within the hour after u take it. pupils being small It Mite.
Your eyes simply take in more light in order to cope with less available light. Thats why when you look in a mirror after you turn a light on your pupils start to shrink.
