Key Specifications

Package Options

Only Sunglasses: Frame and lenses only.

With Original Case: Sunglasses, hard zipper case, brand box, cleaning cloth, stickers, manual, polarized test card.

Lens and Frame Variants — Eleven Configurations

The camo variants (C7, C8, C9) are the most distinctive in the range — grey camo, outdoor camo and black/red camo patterns on the frame surface. C10 white and C11 green are the only non-black, non-camo, non-grey solid colour frames across all seven models. C5 and C9 both feature black and red frame combinations — confirmed by the listing as distinct configurations.

Rubber Temple Covers

The KN1991 adds rubber foot covers at the temple tips — the section of the temple that rests behind the ear. Combined with the rubber nose pads, both contact points between frame and head use rubber rather than hard plastic. This provides a softer feel against skin during extended wear and improves grip behind the ear during active use — particularly relevant for cycling, running and fishing where movement is continuous.

No other model in the range specifies rubber temple covers alongside rubber nose pads.

135mm — The Narrowest Frame in the Range

At 135mm the KN1991 is the narrowest overall width across all eight models — 4mm narrower than the KN0616 (139mm) and 16mm narrower than the KN0910 (151mm). The 113mm temple length is also the shortest in the range. For buyers with smaller faces or shorter head depth who find other models too wide or too long at the temples, the KN1991’s dimensions are the appropriate starting point.

Camo Frame Options

Three camo variants — grey camo (C7), outdoor camo (C8) and black/red camo (C9) — are available exclusively on the KN1991 across the full eight-model range. Camo frames are primarily selected for outdoor activities where frame visibility against natural backgrounds is a consideration (fishing, hunting, hiking) or for buyers who specifically want the camouflage pattern as a design choice.

Complete Range — All Eight Models

Choose KN1991 for the narrowest 135mm fit, rubber temple covers, camo options and the 5-barrel stainless hinges with full rubber comfort package. Choose 0717 for similar 5-barrel hinge quality at a slightly wider 144mm without camo options. Choose KN0616 for 139mm with non-slip nose pads and the widest colour selection (11 variants).

Who Are These Sunglasses For?

The KN1991 is built for:

• Camo frame buyers — the only model in the eight-page range with camo options
• Narrow face buyers — 135mm is the smallest frame in the range
• Maximum comfort buyers who want rubber contact at both nose and temple simultaneously
• White or green frame buyers — C10 and C11 are the only solid non-black coloured frames across the full range
