A protective presbyopia lens is revealed. The protection lens includes a plano lens area and a presbyopia lens area, both being produced by injection molding. The plano lens area and the presbyopia lens area are connected directly without any medium therebetween. The outer surfaces of the plano lens area and the presbyopia lens area are spheres with the same radius of curvature while the inner surfaces of the plano lens area and the presbyopia lens area are spheres with different radius of curvature. The presbyopia lens area includes upper and lower edges, left, and right edges. Both the vertical distance between the upper and lower edges and the horizontal distance between the left and the right edges are ranging from 3 cm to 5 cm. The presbyopia lens area is corresponding to and covering the users eye while being worn. Thereby people with presbyopia can see clearly during work.
