Answer 1

До максимума: если человек напуган
До минимума: елси человек спокоен

Answer 2

Conditions for Maximum Pupil Size

The size of the pupil in the human eye can vary depending on several factors. One of the main factors that can cause the pupil to dilate and reach its maximum size is low light conditions. In dimly lit environments, the pupil expands to allow more light to enter the eye, which improves vision in low-light situations. This is known as pupillary dilation.

When the light levels are low, the iris muscles in the eye contract, causing the pupil to enlarge. This allows more light to enter the eye and reach the retina, where it is converted into electrical signals that are sent to the brain for processing. The maximum size of the pupil can vary among individuals, but it is typically around 4-8 millimeters in diameter.

Conditions for Minimum Pupil Size

On the other hand, the pupil can also constrict and reach its minimum size under certain conditions. The main factor that causes the pupil to constrict is bright light. When exposed to bright light, the iris muscles in the eye contract, causing the pupil to become smaller. This is known as pupillary constriction.

The purpose of pupillary constriction is to limit the amount of light entering the eye in order to protect the delicate structures of the retina from excessive light exposure. The minimum size of the pupil can also vary among individuals, but it is typically around 2-4 millimeters in diameter.

It's important to note that the size of the pupil can also be influenced by other factors such as emotional state, medications, and neurological conditions. For example, emotions like fear or excitement can cause the pupil to dilate, while certain medications or neurological conditions can affect the normal pupillary response.

In summary, the size of the pupil in the human eye can vary depending on the lighting conditions. In low light, the pupil dilates to allow more light to enter the eye, while in bright light, the pupil constricts to limit the amount of light entering the eye. The maximum and minimum sizes of the pupil can vary among individuals but are typically around 4-8 millimeters and 2-4 millimeters in diameter, respectively.
