What are the rods in the retina for?
Rods in the retina are responsible for detecting low levels of light and are important for night vision and peripheral vision. They contain the light-sensitive pigment rhodopsin, which allows them to respond to dim light conditions.
Why does it takes time to see in a dimly lit room when you enter from a brightly lit area?
Your eyes are very clever pieces of equipment. The amount of light in a dark room compared to sun light is 1000s of times different, so your eyes need to adjust to the amount of light to allow you to see things. In the dark, it will increase the size of your iris, which lets light in to the eye. When its bright, the iris shrinks to let a smaller amount of light through. The increasing and decreasing of the iris can take several seconds to adjust which is why at first you cant see anything in a dark room. If too much light enters the eye, it will permanently damage the light sensors (the rentner) at the back of your eye render you blind.

Why is it hard to see bright colors filled with a room filled with candles?
Bright colors are more easily perceived when there is sufficient contrast between them and the surrounding environment. In a room filled with candles, the overall low light levels diminish contrast, making it difficult to distinguish and perceive the vividness of bright colors.
How does color affect readability?
Colours should also be contrasting. Light text on a light backround is hard to see. Dark text on a dark background is hard to see. So you need to get the mix of your colours right so that it is easier to read what you have.
Will a flashlight annoy animals?
Shining a flashlight at night will annoy nocturnal animals. Bright light hurts the eyes, and also ruins the night vision so that it is hard to see in the dark afterwards. That will annoy anyone.

This is why many animals get run over by cars after dark, because the lights make them too frightened to move out of the way.

Why can't a person outside a window see a person inside the window?
Quite often they can see them. However sometimes it is made more difficult by a number of factors. Light reflecting off the window can make it hard to see into a room. As the light levels are different inside and outside, people's eyes adjust differently and that affects what they can see. When you go into a dark place, it is hard to see at first until your eyes adjust. When you go into a bright place, it can be very dazzling until your eyes adjust. When it is dark outside, you have the reverse effect. A person outside the window can see the person inside much easier than the person inside can see the person outside. It is always easier to see from a dark area into a bright area than the other way around.
