Cook Shark 8699 Polarized Driving Sunglasses — Al-Mg Frame, 4-in-1 Lens, Photochromic Gradient

The Cook Shark 8699 is a 145mm aluminium-magnesium rimless-style driving sunglass — the most technically specified Cook Shark at Jewelry Addicts. TAC lens combining four simultaneous technologies: HD polarized glare reduction, photochromic auto-tinting, gradient top-to-bottom tint and anti-reflective coating. Silicone nose pads, Al-Mg frame and temples, 68mm lens width, 12mm narrow bridge, CE certified. Six colour variants.

Key Specifications

Variants — Six Configurations

Black / Black lens: Dark polarized — the most neutral daily option.

Coffee: Brown-toned lens and frame — warm colour rendering.

Smoky Gray: Grey smoke lens — clean and versatile.

Gray / Gun: Grey lens with gunmetal frame.

Blue / Black Frame: Blue mirror lens with black frame — the most vivid.

Transparent / Photochromic Gun: Photochromic auto-tinting with gunmetal frame — the full 4-in-1 lens technology variant.

The 4-in-1 Lens System

The 8699’s TAC lens combines four technologies simultaneously — each addresses a different aspect of visual clarity:

1. HD Polarized: A vertical filter permanently embedded in the lens that blocks horizontal glare from roads, water, glass and wet surfaces. Works at all tint levels — effective even when the photochromic component is at its lightest.

2. Photochromic: The lens darkens in UV light and lightens when UV is absent. Transition speed depends on UV intensity — faster outdoors in direct sun, slower through windscreens and in overcast conditions. Note: car windscreens typically filter UV, reducing the photochromic response while driving.

3. Gradient: The lens is darker at the top and progressively lighter towards the bottom — within the same lens, the upper portion provides stronger sun blocking while the lower portion maintains better visibility for near-distance objects.

4. Anti-reflective: Reduces internal lens reflections and light bounce-back from the rear lens surface — improving overall contrast and reducing visual fatigue.

Gradient Lens — Why It Matters for Driving

The gradient tint is specifically engineered for driving use. When sitting in a car looking forward:

• The upper lens faces the bright sky and incoming sunlight — the darker upper gradient reduces overhead glare and squinting
• The lower lens faces the dashboard, instrument panel, phone holder and navigation screen — the lighter lower gradient allows these to be read clearly without removing the sunglasses

A uniform dark lens requires either squinting at the sky or removing the glasses to read the dashboard. The gradient eliminates this trade-off for most driving conditions.

Al-Mg Rimless-Style Frame

The aluminium-magnesium frame uses a semi-rimless construction — the frame holds the lenses from the top and sides with a reduced lower rim, creating a lighter visual appearance and reducing total frame mass. Al-Mg is lighter than standard plastic at equivalent strength, corrosion-resistant to sweat and environmental exposure, and creates the metallic finish associated with premium eyewear.

The 12mm narrow bridge is the narrowest in the Cook Shark range — appropriate for narrower nose bridges. Buyers with wider nose geometries should compare against the A571’s 30mm bridge.

8699 vs A571 vs A620 — Cook Shark Driving Models Compared

Choose 8699 for the gradient lens driving advantage and the most complete lens technology set. Choose A571 for night vision yellow lens or if 30mm bridge fits better. Choose A620 for the classic pilot/aviator frame with photochromic and adjustable nose pads.

Who Is the Cook Shark 8699 For?

The 8699 is built for:

• Gradient lens drivers who want the top-darker/bottom-lighter tint specifically for dashboard and instrument visibility
• Full-spec buyers who want all four lens technologies (polarized, photochromic, gradient, AR) in one lens
• Al-Mg frame buyers who want the lightweight metal construction over TR90 plastic
• Narrow bridge buyers — 12mm fits narrower nose bridges that would float inside the A571’s 30mm bridge
