hi, I've just done an experinemt to try and show the resolution of the human eye in different light levels.
i did it by putting a 0.25mm apart slits in a tube then, behind it had an adjustbable light, then i moved the slit further back, and asked them to say if they could see the two slits. then i repeated it for different lux levels i.e 0.2, 0.4, 0.6
well anyway, i found out that as you turn the light levels up, it becomes easier to see that there is two slits, but when you get past 2.2lux it makes no difference.
i was wandering what is the calculation to work out the resolution of the eye.
the slite were 0.25mm apart and i went back 10 cm each time.
thank you
