Disclosed herein is a method of manufacturing a plano lens for preventing optical distortion, which is capable of removing an angular difference caused by a spherical lens and minimizing prism action at a specific position, by modifying a refractive mechanism of a plane lens and applying the same to the spherical lens. The method includes a step of setting a normal line to a primary refracting surface of a spherical lens, a step of setting a normal line to a secondary refracting surface of the spherical lens, and a step of adjusting an R value such that the normal line to the primary refracting surface is parallel with the normal line to the secondary refracting surface. |
