Abstract
The rim frame and the lens are continuously restrained to each other over a range other than the gap to stabilize holding of the lens while attachment and detachment of the lens can be facilitated by expanding a gap as consolidating the gaps in the two places into one place due to the deflection of the rim frame and movement of the lens in the left-right direction, whereby the lens can be easily attached and detached without using a tool such as a screwdriver, while can achieve holding stability when fixing the lens and ease of attachment and detachment.
Claims2
Spectacles, comprising:
- a lens;
- and
- a rim frame in which the lens is inserted;
- wherein a gap is formed between the rim frame and the lens at each place only on left and right sides of the spectacles,
- the rim frame is deflectable,
- the rim frame is narrower than an outer shape of the lens in an up-down direction and wider than the outer shape of the lens in a left-right direction,
- the lens is fixed by a force of the rim frame for returning to an original position by deflection of the rim frame,
- the lens and the rim frame are in a circular shape,
- the lens is in contact with the rim frame in an arc,
- the rim frame and the lens are restrained to each other to stabilize holding of the lens, and
- the up-down direction and the left-right direction are orthogonal each other on an opening surface of the rim frame.
