Photons incident on the retina?

[big man]

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?

Zz.

I understand your concern about the estimated number of photons incident on the retina. It is important to approach any calculation with a critical eye and question the validity of the result. However, it is also important to consider the sources and assumptions used in the calculation.

In this case, the estimated number of photons is based on the night sky background, which can vary depending on factors such as location, time of year, and atmospheric conditions. Additionally, the calculation assumes that all photons from the night sky are incident on the eye, which may not be the case.

To ensure the accuracy of the estimate, it would be helpful to provide more details about the calculation method and the sources used. It may also be beneficial to compare the result with other studies or measurements.

Overall, it is important to continue questioning and refining our scientific understanding, and I appreciate your curiosity and willingness to seek clarification.
