At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.What the road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
The BZ Optics RST Mirrored Glasses are cost-effective, bike-focused shades which offer good performance and innovative features aplenty at a competitive price.
The RST Mirrored Glasses have some really neat features. For a start, the arms adjust up and down by up to 15 degrees, thanks to a ratchet system, meaning that no matter what your riding position the lenses can be angled for maximum comfort and protection.
The nose piece is adjustable too, and can be bent into shape to fit 'just so'. All the relevant parts are non-slip.
The lens is non-removeable is a cool-looking Red 'Revo' mirror, which changes from yellow through to red depending on the angle you see it. They are aimed at bright light use, with 12% light transmission.
They're light and comfortable, and the adjustable nose bridge is easy to use and very secure, even if you're getting sweaty. The size of the lenses is generous but not over-large, so they are a good unisex option.
The lenses do a decent enough job of reducing glare on bright days, but they're not quite as dark or relaxing for my eyes as some others I've worn.
I found them just a little too light, but then I do have quite photosensitive eyes. I found best on less ferociously sunny days. The graduated tint isn't particularly noticeable either.
I did experience some fogging of the lens between my eyebrows on a particularly hot and sweaty ride, but on the whole the glasses stay pretty clear.
At £79.99 it's hard to find fault, given their decent lenses and impressive adjustability. Sure, you can get cheaper ones – the Madison Stealth glasses are particularly good value at £34.99 – but it's easy to spend more without getting appreciably more performance.
The BZ Optics RST Mirrored Glasses are perhaps a little too light for the very brightest days, but their adjustability, comfort and performance are impressive.
Well-designed, nicely featured glasses that are comfortable and adjustable
