Our eye ball doesn't become smaller (or larger) its the pupil
that contracts in the presence og bright light The change in size
of pupil controls the light input Now, it becomes smaller in order
to reduce the amount of light entering and thus not overly exposing
it and thus protecting it form potential harm
