The purpose of this project is to determine how outside and inside lights affect one's eyesight. To carry out this experiment an enclosure was constructed with a light and an opening on it, with an outer light source and an eye chart. The volunteer would read the chart.
After the completion of the experiment, it was found that when there is sufficient light outside, conditions inside don't matter. When there is insufficient light outside, the lesser the inside light the better. In other words, if the outside is dark, the lesser the light inside the better.
