A lens testing device includes a light source assembly, a pattern plate, and an imaging sensor. The light source assembly includes a transparent base plate, a light guide plate, and a number of illuminants. The light source assembly uses the light guide plate to uniformize light coming from the illuminants and emit the light onto the pattern plate. The imaging sensor is placed beneath the transparent base plate to sense the light passing through the pattern plate and focused by a lens under test.
