The |embryo| will start development of the |eyes| about the end of the 6th week of interuterine life. During the 7th week the |eyes| have formed, although the skin covering them, the future eyelids, is still intact. In the 8th week the |eyes| already have some coloring. Over the next several weeks the head and face go through several changes, but it is not until approximately the 24th week that the eyelids are no longer fused, although they remain closed. Shortly before birth, about the 40th week, the white part of the |eye| is fairly white and the |iris| is almost always blue. |Eye| coloring is not fully formed in newborn babies, but exposure to light often changes this color within a few weeks.
