First, when the goggles main body 10A is first selected by the wearer of the goggles, the additional lens 20 is selected based on the information about the goggles main body 10A and the eyesight information of the wearer. Determine the design value of. Based on this design value, after adjusting the monomer containing a silicone resin as a main component, an additional lens is manufactured by a casting method and further cut into a predetermined shape. The additional lens 20 thus obtained is attached to the back surface Rg side of the goggle main body 10A according to the design value without using an adhesive, thereby completing goggles suitable for the eyesight of the wearer. |
