The Cook Shark 8793 is a 145mm aluminium-magnesium half-frame photochromic polarized sunglass — the lightest Cook Shark at Jewelry Addicts at 21.8g. TAC polarized UV400 photochromic lens, silicone nose pads, textured anti-slip temple tips, 69mm lens width (the widest in the range), 41mm frame height, 10mm bridge, 132mm temples. Four lens colour variants.

Key Specifications

Variants — Four Lens Options

Silver: Mirror silver lens — the clearest and most reflective.

Gray: Grey tint polarized.

Black: Dark fixed polarized — standard bright-sun option.

Photochromic: Auto-tinting + polarized — the primary variant for variable outdoor light.

21.8g — Lightest Cook Shark

At 21.8g the 8793 is the lightest Cook Shark at Jewelry Addicts — lighter than the 8790 (24.1g), 8038 (18g noted but frame material unconfirmed), A666 (56g) and all driving models. For buyers who prioritise zero-presence wear during long outdoor days, the 8793 is the minimum weight option in the confirmed Al-Mg range.

69mm Lens Width — Widest in the Range

At 69mm the 8793 has the widest individual lens in the Cook Shark range — wider than the KN0910 sunglasses (68mm) and all other Cook Shark models. A wider lens provides more horizontal eye coverage, reducing side light entry and improving peripheral glare blocking. The wide lens combined with the half-frame lower edge maximises the visible field without additional frame weight.

Half-Frame Construction

The 8793 uses a half-frame design — the metal rim runs along the top of the lens only. The lower lens edge is unrimmed, held by a channel or nylon cord. This construction:

• Removes the lower rim weight — contributing to the 21.8g total
• Opens the lower field of vision — less frame intrusion below the lens
• Creates a lighter visual appearance on the face

Combined with the 69mm wide lens, the 8793 provides the widest unobstructed lower-field view of any Cook Shark in the range.

Photochromic Function

The 8793’s photochromic lenses activate under UV exposure — darkening outdoors and lightening indoors. The listing states a 5-second transition — this is the manufacturer’s claimed response time under direct UV. Actual speed varies by UV intensity, temperature and lens condition. Through UV-filtering car windscreens the response is slower; the polarized filter remains effective at all tint levels.

8793 vs 8790 — Two Lightweight Al-Mg Half-Frame Models

Choose 8793 for the lightest weight, widest 69mm lens and the photochromic function as standard. Choose 8790 for more lens colour choices (8 variants including brown) and the marginally narrower 9mm bridge.
