If you have an eye watch, you can definitely turn it. The effect depends on your eye socket and the level of being an eye doctor. In short, many factors cannot be explained clearly in one sentence. Let me tell you something! If your eye lens is customized according to the eye model, plus the activity of the eye surface, the effect is generally very realistic, and you can't see it without looking carefully. The fidelity of the finished product is very poor. I used an imported plastic artificial eye, 5000 yuan. If there is no secretion, I don't need to take it. If I pursue comfort, glass is obviously better. Some finished products in Wuhan are 2 100. If you want to make plastics, I recommend my colleagues in Beijing to do it in Guangzhou.
