Eyes
The eyes are organs. They detect light, regulate the light through a diaphragm, focuses it through adjustable lenses and converts them into electo-chemical impulses in our neurons by photoreceptor cells called rods and cones. The image is converted into a set of electrical signals that are transmitted to the brain via neural pathways that connect the eye to the optic nerve and visual cortex of the brain. In short, eyes are very complex optical systems that convert light to distinguish objects and movement around us.

What is the function of principal axis in eye?
The principal axis in the eye is an imaginary line that passes through the center of the lens and focuses incoming light onto the retina. It helps to ensure that light rays are properly refracted by the lens to create a clear image on the retina for visual perception.
Does your peripheral vision shrink when your tired?
No. Pupil size and the placement of the retina and the placement and concentration of the rod cells (motion detection) on the retina affect it.
Common causes of peripheral vision loss include glaucoma, stroke, branch retinal vein or artery occlusions, ischemic optic neuropathy, and migraine (transient).
Uncommon, or even rare, causes of peripheral vision loss include retinitis pigmentosa, choroideremia, gyrate atrophy, pituitary tumors, optic disc drusen (deposits), brain tumors and aneurysms, and tilted optic discs (nerves). Many other possibilities exist, but are rare.
The distinctions between central and peripheral vision are reflected in subtle physiological and anatomical differences in the visual cortex. Different visual areas contribute to the processing of visual information coming from different parts of the visual field, and a complex of visual areas located along the banks of the interhemispheric fissure (a deep groove that separates the two brain hemispheres) has been linked to peripheral vision. It has been suggested that these areas are important for fast reactions to visual stimuli in the periphery, and monitoring body position relative to gravity [1]
Eye color has no part in it.
Another answer
Loss of your peripheral vision is caused by some other condition, it has nothing to do with your eye color. I'm not an eye doctor but I have Glaucoma and I know the they always are checking to make sure I have not lost any peripheral vision because can cause blindness.
Why do your eyes go out of focus and you have to stare to refocus them?
When your eyes go out of focus, it could be due to eye strain caused by prolonged reading or screen use. Staring helps refocus them by allowing your eye muscles to relax and adjust. It's also a natural response for your eyes to try to bring the object of focus into clearer view.

What does untrained eye means?
You posted this under "Eyes and vision disorders." I'm not sure there is a disorder called untrained eye. Normally, the phrase means simply a person who is unfamiliar with whatever he or she is seeing. In other words, as an example from my line of work, a person who is not familiar with rifles or shotguns would not be able to tell as easily what caliber a gun is by looking at it as easily as someone who is familiar with them could.
Why pontine lesion cause pinpoint pupil?
Pontine lesions can affect the fibers of the Edinger-Westphal nucleus, which is responsible for pupil constriction. Damage to this area can result in unopposed sympathetic input, causing the pupils to become pinpoint due to prolonged pupillary constriction.
What is the prognosis for visual impairment?
The prognosis for visual impairment varies depending on the underlying cause of the impairment. Some conditions may be reversible or manageable with treatment, while others may be permanent or progressive. Early diagnosis and intervention can greatly impact the prognosis for visual impairment.
