Silicon eyeball manufacturing method {Method for producing silicon eyeball}

The present invention relates to a method for manufacturing a silicon eye, and more specifically, to enhance the realism side by increasing the texture, glossiness, transparency of glass, light transmittance, etc. of the eye so that it can be reproduced with full and realistic feeling. The present invention relates to a method for producing silicone eyeballs used for high anthropogenic restoration.

Generally, eyeballs are classified into educational eye models, eyeballs for restoring humanity, medical eyeballs, etc.In order to generate educational eyeballs, corneas, lenses, eyelids, vitreous bodies, choroids, retinas, sclera, etc. It is made of synthetic resin material and has a structure that can be assembled and disassembled.

In the restoration of high humanity, which requires extremely precise expression, acrylic resin eyes, urethane eyes, other silicone eyes, and the like are used.

On the other hand, compared with the urethane eyeballs, the eyeballs using acrylic resins are more frequently used because they are similar to the actual eyeballs in terms of fact. However, the eyes using the conventional acrylic resin also have a problem in that it is insufficient to express the actual eye in terms of texture, glossiness, transparency of glass, light transmittance, etc. in terms of the fact. Accordingly, there is a demand in the art for technology development to provide silicon eyes for high-human restoration more realistically.
