Abstract: A protective lens for people with presbyopia is revealed. The protection lens includes a plano lens area and a presbyopic lens area. Both the plano lens area and the presbyopic lens area are produced by injection molding which is performed by an injection molding machine with a single material outlet. The presbyopic lens area is defined in and connected to the plano lens area. There is no overlap between the plano lens area and the presbyopic lens area. The plano lens area and the presbyopic lens area are connected directly without any medium therebetween. The presbyopic lens area is a circular area with a diameter of 3-5 centimeter. The presbyopic lens area is just corresponding to eyes on people's face after mounted to an eyeglass frame. Thereby the protective lens not only protects people's eyes during working but also allows people with presbyopia see close objects clearly.

Abstract: A protective lens for vision correction is revealed. The protective lens for vision correction includes a plano lens area and an optical lens area. The optical lens area is a round area whose diameter ranging from 3 cm to 5 cm. After the protective lens being cut and mounted in an eyeglass frame, the optical lens area is corresponding to eyes of users. The optical lens area is a concave lens or a convex lens. Thereby users with vision correction needs can wear the protective lens for vision correction conveniently and the protective lens with vision correction function is easy to use.
