[QUOTE="chutinlead, post: 2246467, member: 112603"] That is in a calm scenario. Adrenaline does affect our eyes and age also comes into play as far as max pupil size. [ATTACH type="full" alt="pupil_size_chart(Mar2011).jpg"]286989[/ATTACH] So a 20-29 year old pupil's could dialate as far at 8.8. Using Boomflop's math regarding power and objective size to calculate exit pupil 44/5=8.8mm so you still get maximum exit pupil your eye could handle in the dark at 5 power. Still above 3 and at 3 power its 14.6mm which gives you some eye box. [/QUOTE]
