How long does it take for your eyes to adjust to the dark?
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.
Why do your eyes hurt when you wake up and see light?
When you wake up and see light, your eyes may hurt because they are adjusting to the sudden change in brightness. The pupils in your eyes need time to constrict and adjust to the light, which can cause discomfort or pain. This sensitivity to light is a normal reaction and usually subsides as your eyes adjust.
Why is it hard to see after going from bright light to dark light?
It is difficult to see once entering a dark room after being in bright light because the pupils adjust how much light goes into the eye. In the sunlight, the pupils are tiny. In a dark room, the pupils need a few seconds to adjust to open wider.
Why do your pupil go big in the light?
Pupils dilate in response to light to allow more light to enter the eye and improve vision in low light conditions. In bright light, pupils constrict to reduce the amount of light entering the eye and prevent damage to the retina.
Why does my vision turn red in the dark?
When you are in the dark, your eyes adjust to low light by dilating the pupils to let in more light. This can cause the red color of blood vessels in the back of your eye to become more visible, giving the appearance of red vision.
What happens if you have slow pupils?

No. Normally human eyeballs have their pupils behind their iris so that the eye can adjust to light but fish eyes have their pupils protruding through the iris so that it cannot adjust its eyes to light.
Why cant you see less when your pupils get smaller?
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.
How long does it take your pupils to aguste to the light?
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.
Why is it that when there is sudden darkness the sight is not clear?
your eyes are trying to adjust to the amount of light . when there is lots of light, your pupils get smaller and when there is not enough light, your pupils get larger. therefore, when a bright light turns off and leaves you in sudden darkness., your pupils are widening to adjust to the amount of light it needs to let in. TRY IT YOUSELF: -make the room dark -stand in front of a mirror with a flashlight -shine the light in your eye and watch your pupil close up -then shine the light into the mirror (away from your eye but still so you can see it) and -watch your pupil get larger
Do cats pupils adjust faster or slower then humans pupils?
Cats pupils adjust just a little slower than humans pupils.Actually the answer above is not correct at all. Cats eyes adjust almost faster than humans.

When nothing is wrong with the cats there pupils are normal, like a perfectly smooth rhombus.
What happens when the pupils doesn't change size what happens if they remain large and why does they remain large?
Dilated pupils not responding to light occurs in deep coma and death. The iris doesn't contract, thus pupils fail to automatically respond to light.
Do you have to think about it when you want the size of your pupil to change?
No; the change in the size of your pupil is an involuntary action, meaning that it happens without you thinking about it. The size of your pupils adjust to stimuli, such as bright light. If a bright light was shined in your eyes, your pupils would get smaller in order to let as little light in as possible. Reversely, if you're in a dark room, your pupils will get bigger to let in as much light as possible.
Why can't you see after the lights go out?

How long does it take the eye to adjust from darkness to light?
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.
