The present invention relates to a method of manufacturing a soft contact lens for presbyopia that forms a light penetration region having a given diameter in a center of the soft contact lens to selectively interrupt the light entering an eye and thus increase the depth of focus. Also, a light interruption region having a give diameter is formed around the light penetration region, and micro holes are formed in the light interruption region so that the distribution density of the holes is increased toward the outside, thereby ensuring the amount of the light which may be insufficient due to the light interruption region, and thus ensuring the light visual field. Also, since the light penetration region and the light interruption region are tinted by a color to adjust the contrast sensitivity and, thereby interrupting ultraviolet rays or blue light and thus to prevent damage to optic nerve or visual cells. |
