What does Zeiss digital lens and garage mean?

Early lenses were all formed by lathe processing, so they were called garage sheets.

Theoretically, it can be accurate to 1. At present, most garage parts are also received on the 25th. Of course, the parameters such as pupil distance, aspheric surface, astigmatism and axial position will be customized accordingly, so that the matching effect can reach the best state (not only the thickness is more uniform). Because of the wide pupil distance, reading glasses are generally equipped with 50 files and 25 files. Myopia lenses are generally designed according to 25, and astigmatism is also designed according to 25. If it exceeds 200, it needs to be customized.

Pupil distance is the distance between the pupils of both eyes. Normal people's eyes look at the same object, which is imaged on the retinas of both eyes and overlapped in the visual center of the brain to form a complete three-dimensional single object. This function is called binocular monocular vision. However, in the process of binocular monocular vision formation, infants are easily influenced by external factors, resulting in one eye staring at the target, and the other eye tilting, unable to see the same target, so strabismus occurs. In medicine, the eyeball squints inward when staring at an object, which is called esotropia, which is also commonly known as "cross-eyed".
