Key Features
Overview
Heat Wave Visual Carat Sunglasses: Ultra Black are fashion sunglasses built for bright outdoor conditions and everyday wear with a sharper, more modern cat eye shape. This is a pair of sunglasses designed for glare reduction and eye protection in intense sun. Model Number: E_CAR_BLACK_01U.
The big story here is the Ultra Black lens. Heat Wave rates this lens at 6% visible light transmission, which is notably darker than the common 11% range mentioned in the source data. In plain terms, these are meant for hard sun, reflective environments, and people who want a much darker lens than the average fashion frame offers. Snow, sand, white roofing, and poolside use are exactly the kind of situations where that darker tint earns its keep.
The Carat frame takes a classic cat eye direction and cleans it up with a flush-mount flat lens design, a high gloss black frame, and polished gold details. That gives the sunglasses a more structured, less soft look than a traditional rounded cat eye. If you want something that still reads stylish but does not feel overly delicate, that design choice matters.
Fit is another real advantage. The arms have a wire core embedded in the polycarbonate frame, which lets you twist, bend, and fine-tune them for a better fit. That is useful if you have dealt with sunglasses that slide at the nose, sit unevenly at the temples, or feel too tight behind the ears right out of the box. Being able to tune the arms makes these more wearable day to day instead of just looking good for ten minutes.
On the lens side, Heat Wave calls out 1.9 mm polycarbonate construction, UV400 protection, and 100% UVA and UVB blocking. The source data also states the lenses are tested for clarity, color, and light transmission standards, and that the product meets Z80.3 standards. That combination tells you these are not just dark lenses for appearance. They are built to give actual sun protection with impact-resistant polycarbonate material that makes sense for regular outdoor use.
One important note that buyers should know up front: the source data specifically says these lenses are legally not intended for use while operating a vehicle because of how dark they are. That is not a minor detail. If you want one pair for driving and all-purpose wear, this specific Ultra Black version may be too specialized. If your priority is maximum darkness for harsh sun, though, that is exactly why you would choose it.
These sunglasses make the most sense for people who want a fashion-forward frame with genuinely aggressive sun control. They fit shoppers looking for women’s sunglasses, cat eye sunglasses, and dark-lens outdoor sunglasses that can move from casual daily wear to bright open environments without looking like technical sport eyewear. If you like the cat eye profile but want something cleaner, darker, and easier to personalize at the temples, the Carat is a smart buy.
Built for Brutal Brightness
If you spend time around highly reflective surfaces, lens darkness is not just a style choice. The Ultra Black lens is meant for the kind of sun that bounces hard off snow, sand, concrete, water, and light-colored surfaces.
- 6% visible light transmission for a much darker view than standard sunglass tints
- UV400 protection with 100% UVA and UVB blocking
Modern Cat Eye, Easier Fit
The frame keeps the cat eye look but tightens it up with a flatter lens shape and cleaner lines. Just as important, the adjustable wire-core arms let you dial in the fit instead of settling for whatever comes out of the box.
- Flush-mount flat lenses for a cleaner, more modern profile
- Wire-core temples embedded in the frame for bend-to-fit adjustability

Pro Tip
Buy these for harsh daylight, not as your one-pair-for-everything sunglasses. With a 6% tint, the Ultra Black lens is best when the sun is punishing, and the source data specifically says it should not be used when operating a vehicle.
