Dual Strength Bifocal Sunglasses Dark Tint In Black - The Card Shark combine everyday sun protection with custom close-up support in a clean, wearable rectangular frame. Designed for unisex appeal, this style offers a balanced average fit, lightweight plastic construction, and a polished silhouette that feels easy to wear for driving, travel, outdoor reading, and day-to-day life in bright conditions.
With its dark tinted sunglass look and practical bifocal design, The Card Shark is a smart choice for anyone who wants stylish outdoor eyewear with more personalized reading support than standard readers can offer.
Custom Bifocals
This style is made as a dual-strength bifocal sunglass, allowing you to customize the magnification power in the upper and lower reading segments. That means you can choose one strength for one viewing need and a different strength for another, all within the same pair.
A dual-strength bifocal design can be especially helpful for people who want more flexibility for different near-vision tasks, such as checking a phone, reading outdoors, viewing a dashboard, looking at instruments, or switching between close-up and slightly farther reading distances.
Dark Tint Outdoor Comfort
The dark sunglass tint helps reduce brightness while keeping your frame versatile enough for outdoor errands, patio lunches, beach walks, travel days, and sunny afternoon reading. It is a practical way to combine reading support and sunglass convenience in one frame.
Lightweight Plastic Construction
Crafted from plastic, The Card Shark offers a lightweight feel that stays comfortable through daily wear. The rectangular shape gives the frame a clean and confident profile, while the average-width fit makes it a versatile option for a wide range of face shapes.

Why Traditional Readers Fall Short
You can’t see everything clearly at once
Your book is sharp, but your screen isn’t.
Why it happens:Traditional readers focus at only one fixed distance.
Result:You lean forward, tilt your head, or constantly adjust.
You keep switching glasses
On. Off. Swap pairs. Repeat.
Why it happens: Standard lenses aren’t built for how people actually move between tasks.
Result: You now manage two pairs of reading glasses to navigate your day.
Your eyes feel tired too soon
By afternoon, your eyes feel strained.
Why it happens:Your eyes compensate when lenses don’t match real working distances.
Result: Fatigue, tension, and reduced comfort.
