The invention discloses an optical lens assembly. The optical lens assembly comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens and a seventh lens in sequence along an optical axis from an object side to an image side, wherein each lens has an object side surface facing the object side and an image side surface facing the image side. The optical lens assembly only has the above seven lenses having refractive power and the lenses accord with the limitation of certain optical conditions.
