There are provided an optical lens and a lighting apparatus using the same. The optical lens includes an incidence part provided as a light incident area and including a micro lens array formed on at least a partial region of a surface thereof; a reflection part spaced apart from the incidence part by a predetermined distance and reflecting at least a certain amount of light having passed through the incidence part; and a side surface part connecting the incidence part and the reflection part and transmitting the certain amount of light reflected by the reflection part. In the case of using the optical lens, when light incident from the light source is emitted to the outside, an angle at which the light is emitted therefrom is enlarged, whereby an orientation angle of the light source is improved.
