The Heat Wave Rayth: A Z87+ Buyer's Guide
The Rayth is the Heat Wave frame for people who hate the feeling of glasses on their face. It sits low and close, wraps just enough to keep grinding dust and brake debris out of the corners of your eyes, and weighs little enough that you forget you put it on. Heat Wave calls it "lean and locked-in," which is shorthand for a real thing: a Z87.1+ frame cut down to the smallest shape that still passes the test. If the big wraparounds slide down your nose or swallow a narrower face, this is the one to look at.
What the Rayth actually is
Two frames share the Rayth name, and the difference is the lens. The Heat Wave Rayth Z87 is the base model at $70, a polycarbonate low-profile performance frame rated ANSI Z87.1+ for both high-velocity and high-mass impact, shipped with a microfiber pouch. The Heat Wave Performance Rayth Photochromic is the $100 version, built on the same frame with the Easy Rider photochromic lens and side shields installed from the factory.
That Z87.1+ stamp is the part worth slowing down on. The plus sign is not decoration. It tells you the frame passed the high-mass impact test, a pointed weight dropped from height, on top of the high-velocity test, a quarter-inch steel ball fired at the lens. Plenty of "safety" sunglasses carry a bare Z87 without the plus, which means they cleared a lower bar. The Rayth carries the plus, the same mark defined in the ANSI/ISEA standard. If you want the full breakdown, we wrote a plain-language explainer on the Z87.1 mark.
The photochromic lens is the reason to spend the extra $30
Here is the case for the Performance Rayth Photochromic. The Easy Rider lens reads the light. Indoors, in the bay, under the lift, it sits at roughly 75% VLT, close enough to clear that you can read a sidewall stamp or a torque spec without pushing the glasses up onto your forehead. Walk out to the lot and it darkens to about 17% in a few seconds, a true sunglass tint. One frame covers the indoor job and the outdoor one, so a tech stops doing the thing every tech does, which is owning a clear pair and a dark pair and losing both by Thursday.
One pair that is clear at the workbench and tinted in the parking lot beats two pairs you keep misplacing.
For the longer story on how photochromic lenses behave on a Z87 frame, including where they fall short (they barely darken behind a windshield, for one), see our Heat Wave photochromic buyer's guide.
Fit: who the Rayth suits and who should size up
Heat Wave lists the Rayth as a fit for round and oval faces, and the operative phrase on the spec sheet is "low-profile." This is a smaller, closer frame than the Vise or the Skynet. On a narrower or medium face it locks in and disappears. On a wide face or a big head it will pinch at the temples and you will want more frame. If that is you, the Heat Wave Performance Vise runs larger and comes in fourteen frame-and-lens combinations, including a clear anti-fog lens built for indoor shops, and the Performance Lazerface is the bolder, flatter shield if you want presence. We go deeper on sizing in our fit guide for small and large faces.
How the Rayth fits in the Heat Wave Z87 lineup
The Rayth's job in the lineup is small and serious. The Vise is the do-everything frame with the deepest lens menu. The Skynet is the wider wrap with the most coverage and its own anti-fog option. The Rayth is what you reach for when those two feel like too much glasses for your face. If fogging is your specific enemy in a humid bay, the anti-fog lens lives on the Vise and the Skynet rather than the base Rayth, and we put together an anti-fog troubleshooting post that applies to any frame you own.
Outfitting a crew, not just yourself
If you are buying for a shop and not for one face, the low-profile Rayth earns its spot as the frame for the holdouts, the techs who refuse safety glasses because the big ones bounce, fog, or look ridiculous to them. OSHA requires eye protection wherever there is a reasonable probability of injury (29 CFR 1910.133), and the only protection that does any work is the pair a tech actually keeps on his face. We run volume pricing and a managed reorder setup through our corporate safety-eyewear program, which is the right door if you are kitting out a whole bay.
Common questions
Is the Heat Wave Rayth actually Z87 rated?
Yes, and it carries the plus. Both the base Rayth Z87 and the Performance Rayth Photochromic are rated ANSI Z87.1+ for high-velocity and high-mass impact, which is the higher of the two impact ratings under the standard.
What is the difference between the Rayth and the Rayth Photochromic?
Same frame, different lens. The base Rayth Z87 is $70 with a fixed lens. The Performance Rayth Photochromic is $100 and uses the Easy Rider lens that shifts from about 75% VLT indoors to 17% in sunlight, with side shields installed.
Will the Rayth fit a bigger face?
It is a low-profile frame built for round and oval faces, so a wide or large head will likely find it tight at the temples. Size up to the Performance Vise or the Skynet if you need more coverage.
Does the photochromic lens work for driving?
Not really. Photochromic lenses react to UV, and most windshields block enough UV that the lens stays lighter than you would want behind the wheel. It is built for walking between indoor and outdoor work, not for the cab of a truck.
Is the Rayth any good for the range?
It is a Z87.1+ frame, so it clears the impact bar most ranges ask for, and the low-profile wrap sits cleanly under ear pro. For a purpose-built ballistic pick, start with our shooting and range collection.
The Rayth is the easy Heat Wave to hand to anyone who has spent years skipping safety glasses because every pair felt like wearing a fish tank. If that sounds like you, the base Rayth Z87 at $70 is the place to start, and the rest of the Heat Wave frame lineup is right there when you want to hold it up against the bigger shapes.
