What makes a human dazzled in the eye after being in a dark room and suddenly exposed to light?
When a human is in a dark room, their pupils dilate to allow more light to enter the eye and improve vision in low light conditions. When suddenly exposed to bright light, the pupils constrict rapidly to reduce the amount of light entering the eye. This rapid adjustment in pupil size can cause a temporary dazzled or blinded sensation as the eyes adapt to the change in lighting conditions.
When your pupils dilate are you lying?
While dilated pupils can sometimes indicate arousal or interest, they do not necessarily mean someone is lying. Pupil dilation can also be triggered by changes in light, mood, or even certain medications. It is important to consider other behavioral cues and verbal indicators when trying to determine if someone is lying.

Why do people eyes dilate while they are talking to you?
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.

Why do pupils constrict?
Pupils constrict when an object is brought closer to the eyes, to help them focus properly on it. Also pupils constrict when hit by light, the brighter the light, the bigger the constriction. If an equal amount of light shines into both eyes, the degree of constriction is generally equal. However, if the light is directed primarily into one eye (i.e., with a flashlight), the pupil of that eye greatly constricts (direct reflex) while the pupil of the other eye shows a much smaller degree of constriction (consensual reflex).
What dilate the pupils of the eyes?
There are many things that can dilate the pupil of the eye. First of all, light plays a huge factor. Also, if there are unknown, alien substances in your body, such as drugs, that is also a pupil dilator. Also, if you have recently suffered a concussion, your pupils might be dilated for a while. Pupils also dilate when focusing on different planes of vision, as well as different distances.
What controls your pupils becoming larger?
Pupil size is primarily controlled by the iris muscles, which respond to light levels and emotional stimuli. In bright light, the circular muscles contract to constrict the pupils, while in low light, the radial muscles contract to dilate them. Additionally, factors such as arousal, stress, and certain medications can also influence pupil size. The autonomic nervous system plays a key role in regulating these responses.
