摘要： Disclosed is a method for manufacturing a three-dimensional article, including: a step of producing the article by an additive manufacturing technology, the article including at least two parts that face, at least partially, each other or that have edges facing, at least partially, each other; and a step of finishing of the article. According to the invention, the two parts are produced together with a temporary connection that links the two parts, and the method includes, after the step of finishing, a step of unlinking the temporary connection in order to separate the two parts.

摘要： An optometry device for binocular testing of the eyes of a subject, including a binocular refraction test unit with a first optical refraction element adapted to provide different vision correction powers along a first optical axis and a second optical refraction element adapted to provide different vision correction powers along a second optical axis, and a display system for providing a first and a second test images, the first test image being conveyed to the first optical refraction element along a first optical pathway and the second test image being conveyed to the second optical refraction element along a second optical pathway. The first and second test image being provided with details smaller than 1 arc minute, over a field of view of at least 8° in horizontal directions, the first and second optical pathways having a length between 25 and 100 centimeters.
