The pupil size is controlled by the iris muscles. In bright light, the iris constricts the pupil to reduce the amount of light entering the eye. In dim light, the iris dilates the pupil to allow more light to enter. Emotional responses or changes in focus can also affect pupil size.
"Blood shut eyes" is likely a typo or a misunderstanding. It may refer to eyes that are closed due to swelling or irritation, giving the appearance of being shut.

Yes, it is possible to sneeze without blinking, although blinking during a sneeze is a natural reflex for many people. The sensation of a sneeze and a blink are controlled by different reflex arcs in the body.
Rod cells are light sensitive due to the presence of a light-sensitive pigment called rhodopsin, which is made up of a protein called opsin and a molecule called retinal. When light enters the eye and hits the rhodopsin, a chemical reaction is triggered that leads to the generation of electrical signals, which are then transmitted to the brain for processing. This process allows rod cells to detect and respond to low levels of light.
The type of joint movement used to shut off a light is flexion of the elbow joint. This movement brings the hand closer to the shoulder, allowing the fingers to reach the light switch and flick it off.
It happens so to protect our eyes from the bright light.When the harmful light rays hit the retina,the brain forces us to shut our eyes by making us sneeze.
You can only see that car's headlights since you are just focusing your eyes in it not in the entire car. Your eyes adjust to the light by using an 'iris'. When bright light is shone into your eyes, the iris shuts down to protect your eyes. The surrounding area, especially behind the light, is many times darker. Because your eyes have shut down the light, there is not enough light entering your eyes to see the darker areas.
Yes.
When suddenly exposed to bright light, your pupils will automatically constrict (actually the constrictor muscles of the iris will contract, causing the iris to expand and narrow the pupil). Also, it is likely your eyelids will squint shut.
