Pupil
Smaller
It can be bigger or smaller, but not equal to.
Dilated pupils are bigger, and constrictred pupils are smaller.
Both. It is smaller than 4.1 and bigger than 3.9
your eye would explode
The dilator muscle which makes the pupil larger and the constrictor muscle which makes the pupil smaller.
The same as ours do... light constricts (smaller), darkness dilates (larger) the pupil.
When a light is shined into your eye, your pupil constricts (gets smaller) as a natural response to regulate the amount of light entering the eye. This helps to protect the sensitive inner structures of the eye from damage.
Smooth Muscles.
They become bigger and widder
its not just parakeets its everyones eyes when light enters the eye the pupil doesnt get bigger its the color around the pupil that gets bigger or smaller the pupil is wut the light goes through. then it reflects againts the back of your eye and that's how you see things
The iris is the part of the eye that controls the size of the pupil. In bright light, the iris constricts the pupil to reduce the amount of light entering the eye, while in dim light, the iris dilates the pupil to allow more light to enter and improve vision in low-light conditions.
That is the pupil, which is essentially a hole in the iris that allows light to enter the eye. The pupil can change size in response to different lighting conditions and levels of arousal.
The muscles that make the pupil smaller or bigger, or the retina, contain pigment, and the color of pigment is based on your genes.
When a light is not shined into an eye the pupil contracts gets bigger because the eye needs all the light being presented to it. If the light is not taken away the pupil does not dilate. PS like the eye gets smaller in the light.
When the pupil of the eye is exposed to light, the muscles surrounding the pupil contract, causing it to constrict. This helps to reduce the amount of light entering the eye and minimizes glare, allowing for better focus and vision in bright conditions.
