In addition to controlling the amount of light that enters the eye, the pupillary light reflex provides a useful diagnostic tool. It allows for testing the integrity of the sensory and motorfunctions of the eye.[1]
Under normal conditions, the pupils of both eyes respond identically to a light stimulus, regardless of which eye is being stimulated. Light entering one eye produces a constriction of the pupil of that eye, the direct response, as well as a constriction of the pupil of the unstimulated eye, the consensual response. Comparing these two responses in both eyes is helpful in locating a lesion.[1][5]
For example, a direct response in the right pupil without a consensual response in the left pupil suggests a problem with the motor connection to the left pupil (perhaps as a result of damage to the oculomotor nerve or Edinger-Westphal nucleus of the brainstem). Lack of response to light stimulation of the right eye if both eyes respond normally to stimulation of the left eye indicates damage to the sensory input from the right eye (perhaps to the right retina or optic nerve).[1]
Emergency room physicians routinely assess the pupillary reflex because it is useful for gauging brain stem function. Normally, pupils react (i.e. constrict) equally. Lack of the pupillary reflex or an abnormal pupillary reflex can be caused by optic nerve damage, oculomotor nerve damage, brain stem death and depressant drugs, such as barbiturates.
Normally, both pupils should constrict with light shone into either eye alone. On testing each reflex for each eye, several patterns are possible.[6]
Yes, the adaptive value of the spinal reflex is primarily due to its speed of response. The reflex allows for quick reactions to potentially harmful stimuli without needing input from the brain, which is important for survival in potentially dangerous situations.
The convergence reflex helps our eyes move toward each other when focusing on near objects. This reflex allows both eyes to focus on the same point, enabling depth perception and clear vision at close distances.
The value 24.503 has 5 significant figures.
The value of a reflex action is to survive. For example, if we place our hands on a hot oven. Our reflex would be to take our hand off and register the pain. OR A perfect example would be the rooting reflex. Which helps a breastfed infant find the mother's nipple. Babies display it only when hungry and touched by another person, not when they touch themselves.
The only way to see the value is on Ebay. You can search previous auctions of similar cameras, or just offer it for sale, with or without a minimum. Even if you had a catalog of values, they wouldn't be current. Good luck.

It is a complete turn of 360 degrees which is the maximum value of a reflex angle

No, 180 degrees is a straight angle. A reflex angle is one whose value is between 180 and 360 degrees.
Five significant figures.
4 significant figures.
Probably one to four depending on condition and accsesories
Because
the maximum value of the dependent variable of a wave/signal/response is called the amplitude of that wave/signal/response respectively .
