[0027] (First embodiment)
[0028] Below, use Figure 1 ~ Figure 3 The first embodiment of the method for manufacturing spectacle lenses and the coating liquid coating device for spectacle lens substrates of the present invention will be described in detail.
[0029] The manufacturing method of the spectacle lens of this embodiment is as follows figure 1 Implementation as shown in the flowchart. That is, the lens positioning step S1, the coating step S2, and the high-speed rotation step S3 are sequentially performed. In the coating step S2, the coating liquid coating step S2a and the coating liquid expanding step S2b are sequentially performed, and the details will be described later.
[0030] In the lens positioning step S1, such as Figure 2A As shown, the spectacle lens substrate 1 is positioned between a pair of nozzles 2a and 2b for coating liquid application. The spectacle lens substrate 1 is formed in a disk shape, and is arranged such that the optical axis C of the lens su...

[0061] (Second embodiment)
[0062] Next, use Figure 4 The second embodiment of the manufacturing method of the spectacle lens of the present invention will be described in detail with FIG. 5. in Figure 4 And Figure 5, for and use Figure 1 ~ Figure 3 The same or equivalent members are denoted by the same reference numerals, and detailed descriptions are appropriately omitted.
[0063] The method of manufacturing spectacle lenses of this embodiment can be used image 3 The illustrated spectacle lens substrate is implemented by a coating liquid coating device 11. In this embodiment, the disc-shaped spectacle lens substrate 1 is also processed in a state where the optical axis C is directed in the horizontal direction. In addition, in this embodiment, a thermoplastic coating liquid, a thermosetting coating liquid, an ultraviolet curable coating liquid, etc. can also be used.
[0064] In the method of manufacturing spectacle lenses of this embodiment, first, implement Figure 4 The...
