The pupil
In the Glasgow Coma Scale, pupil size is typically observed before applying light stimulation. This is done to assess the initial baseline size of the pupil before assessing how it reacts to light, which is an important indicator of neurological function.
When a pupil is "blown," it typically refers to dilation or enlargement due to factors like emotional arousal, drug use, or head injuries. This can temporarily increase the size of the pupil, affecting vision and light sensitivity. It's important to seek medical attention if the blowing of the pupil is sudden and unexplained, as it could indicate a serious underlying condition.
The size of the pupil in the human eye is controlled by the iris, which is a ring of muscle that can expand or contract to adjust the size of the pupil.
Yes, pupil size should not be affected by the focal distance, unless there is a change in the amount of light at that distance. To change focal distance, the lens contracts or expands. The pupil dilates and constricts based upon how much ambient light there is.
No nothing can be done at all here.

The size of the pupil decreases in bright light to reduce the amount of light entering the eye, protecting it from damage. In darkness, the pupil enlarges to allow more light to enter the eye, enhancing visibility in low-light conditions. This process is controlled by the iris muscles in response to changes in ambient light levels.
You could easily increase the font size and decrease it. It could be done with the help of Shortcut keys i.e. Cntrl and + or -.
