Claims

[Scope of Claim for Utility Model Registration] (1) An ocular loupe that is used close to both the left and right eyes, which has a power of 3D (dioptre) or less,
In a lens that has the same optical axis and has an effective diameter that exceeds the average pupillary distance of the left and right eyes, the part that faces the left and right eyes when the optical axis corresponds to the approximate center between the left and right eyes. An eyepiece type loupe, characterized by having the eyepiece as an eyepiece part. (2) The eyepiece type loupe according to claim 1, characterized in that an objective lens portion having a larger power than the lens is integrally formed in a portion other than the eyepiece portion.
