Heat Wave Visual Performance Rayth Sunglasses: Photochromic Z87+ are performance safety sunglasses built for users who need eye protection that can handle changing light. This is a pair of safety sunglasses designed for impact protection, glare control, and all-day wear across indoor and outdoor environments. Model Number: E_RAYTH_07T.

The big story here is the photochromic lens. Instead of locking you into a dark lens that can be annoying indoors, these lenses adapt from a very clear 75% VLT down to 17% VLT depending on light intensity. Heat Wave states the transition happens in under 30 seconds, which is a practical advantage if your day moves from garage work to the driveway, from the truck cab to the jobsite, or from early morning to full sun.

Protection is not just a marketing claim on this model. The lenses are 2 mm thick polycarbonate and meet or exceed ANSI Z87 mass impact requirements. With the Quick-Latch side-shield system installed, the glasses meet ANSI Z87+ standards while also adding lateral protection from debris and side light. That makes these a more serious option for people who actually need safety-rated eyewear, not just sunglasses with a rugged look.

The Rayth frame is built around a bold, flat-profile lens shape with a compact top-to-bottom design and a standard-width fit. In plain terms, you get a wide, tough-looking frame that does not feel overly tall on the face. Heat Wave also calls out premium frame detailing, and the design adds rubberized Hytrel inserts in the arms and nose area for better grip where it counts.

Those fit details matter more than they sound. The modified arm design is intended to reduce wear and hair snags, while the increased rubber surface at the nose helps the glasses stay planted when you are moving, sweating, or constantly looking up and down. If you have worn safety glasses that slide forward or catch your hair every time you pull them off, this is exactly the kind of small improvement you notice fast.

On the lens side, you also get UV400 protection with 100% UVA and UVB blocking, plus a category 1 to 3 tint range. Heat Wave specifically notes that these will not get as dark as their standard black lenses, and that is actually useful to know before you buy. The tradeoff is better indoor clarity and more versatile day-to-day wear, which is the whole point of a transition lens in the first place.

These Performance Rayth sunglasses make the most sense for users who split time between indoor and outdoor work, drive throughout the day, or want one pair of safety-rated glasses instead of separate clear and tinted pairs. If you are in fabrication, automotive work, shop work, ranch use, property maintenance, or you just want ANSI-rated eyewear that does not need constant swapping, this model has a clear use case.
