This is a difficult question to answer. Obviously too much light can damage the eye, which is why you should not look directly at the sun, but it is very difficult to quantify, as amount of damage varies with wavelength and length of exposure. It's often the uv light, which we can't even see, which does the most damage. If there is less light than this, then the eye is extremely adaptable and can work at a wide range of light intensities. The iris controls how much light gets in, opening the pupil wide in dim light, and we have two types of light receptor in the retina, rods, which operate well in dim light and cones, which work best in bright light.

The pupil is actually the absence of the iris (colored part of the eye), so it only allows light to pass through it and helps control how much light passes to the back of the eye.
