An ocular comprising a magnifying device including first and second pair of lenses (22, 24;
- 22, 24) defining respective first and second substantially parallel optical paths, a frame (14, 16) defined by a holding portion (16) for holding the ocular on a human head and a supporting portion (14) for supporting said first and second pair of lenses (22, 24;
- 22, 24), means (40, 60) for separately and independently snap-attaching and detaching said first and second pair of lenses (22, 24;
- 22, 24) relative to said supporting portion (14) in individual sliding relationship thereto, each of said snap-attaching and detaching means (40, 60) including at least a pair of fastening arms (42, 44;
- 64) defining a space there-between, at least one fastening arm of each pair of fastening arms (42, 44;
- 64) being constructed from resilient material to effect snap-attachment and detachment of said supporting portion (14) relative to said space, and said pair of fastening arms (42, 44;
