SUMMARY

The estimated number of photons incident on the human retina per second from the night sky background is approximately 6 x 1010. This figure is contingent upon specific parameters related to the light intensity of the night sky, which were not provided in the initial query. Without these parameters, it is impossible to verify the accuracy of the estimate. Accurate calculations require detailed information about the light source and environmental conditions.

PREREQUISITES
  • Understanding of photon flux and light intensity
  • Basic knowledge of human visual physiology
  • Familiarity with astronomical light sources
  • Ability to perform calculations involving light measurements
NEXT STEPS
  • Research the principles of photon flux in photometry
  • Study the characteristics of night sky brightness
  • Learn about the human retina's response to light
  • Explore methods for measuring light intensity in various environments
USEFUL FOR

Physicists, optometrists, astronomers, and anyone interested in the interaction between light and human vision.

Sorry I just want to check that this is a reasonable estimate.

I calculated the amount of photons incident on the eye per second is about 6*10^10. This is from the night sky background and just seems way too much.
Sorry for such a stupid question.

thanks for any help

There is no way to check if this is a "reasonable estimate" if you do not tell us the parameters that you started with. What are the numbers you used as the starting point such as the amount of light from the night time sky?
