I don't quite understand why, but a lower intensity of light can offer much better contrast.
It also might be less destructive to the cells and therefore offer better observation, unless you want to watch 'em cook.

2 reasons- it is easier to see the cell if the light is dimmed and also (and more inportantly) it will cause less damage to your eyes. It is a proven fact that extended microscope use damages the eyes and will make you begin to wear glasses or strngthen your prescription.

To diffuse the bright light and see the specimen in more detail. if they are transparent then the bright light passes through to easily. so by lookin at them through different brightnesses it is easier to see details. Also try staining the cells by using a simple stain or a gram stain.

Because if it's too bright you can't see the details of the cells.
