Abstract
The invention discloses an optical lens for a light-emitting device. The optical lens includes a translucent body which has a concave inner surface to which light is incident. The inner surface includes a first region and a second region opposite to the first region. The first region and the second region are both substantially straight planes and extend inclinedly from the edge of the inner surface to the center of the inner surface respectively, so as to connect with each other. Thereby, the optical lens of the invention is capable of contributing to an elliptic light field.
