Q: is the working distance already in the schematic eye or do you have to manually do that youself? I would prefer it be the latter option

You can view the attached video, hope it will be helpfull to you. The working distances of our products are 50 cm, 67 cm, and 1 meter. They cannot be adjusted at will. Our technicians recommend using 50 cm directly. Looking forward to your order

Q: I don’t understand your answer regarding the working distance. And how do I know which diopter the schematic eye is set at?

Thank you very much for your interest in our products. Here are the answers to your questions: 1. “The distance” refers to the distance between the person using the retinoscope and the simulated eye, which needs to be adjusted by yourself. “The distance” is specified according to the relevant standards of retinoscopy. For example, if the distance is 50 cm, and a 100-degree lens can be used to find neutralization, then you need to add -200 degrees. The measured reading is -100+(-200)=300 degrees . If it is 67 cm, you need to put a 150-degree lens to find the neutralization, that is, add -150, and the total reading is still -150+(-150)=300 degrees. Our technicians recommend using 50 cm directly. 2. Just adjust the diopter to 0. Our Schematic Eyes are generally used by professionally trained people.
