Abstract
An optical lens is provided. The optical lens includes, in order from an object side to an image-forming side, a first lens having refractive power, a second lens having refractive power, a third lens having positive refractive power, a fourth lens having positive refractive power and a fifth lens having refractive power. The object-side surface of the first lens is a concave surface or a flat surface. The overall optical effect of the first lens and the second lens is negative refractive power. The refractive rate on the object-side surface and/or the image-side surface of the fifth lens from the center point in a radial direction away from the optical axis changes in the same tendency.
