Oakley Jawbreaker Prizm Road



Larger lens provides less obstructed field of vision than most other glasses, and new Prizm Road lens offers impressive clarity

At 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.

Oakley's Jawbreaker Prizm Road glasses might evoke memories of Greg LeMond's Eyeshades, which transformed the professional peloton forever back in the 1980s, but these are thoroughly modern and packed with the latest tech. Enough to make them a worthy successor to the venerable Radars that have long been a favourite of the professional and amateur racing cyclist.

First things first, the Jawbreakers certainly have a very bold and very distinctive appearance. A bit like Marmite, you'll either love them or hate them. I urge you to at least try them on before you write them off hastily. The shock of the new has subsided now that they're almost commonplace among the professional peloton and local club run. Their looks don't win them immediate fans, but after one ride in them you might find yourself unable to go back to your previous glasses. This happened to me.

The Jawbreakers were developed in collaboration with Mark Cavendish, a sprinter renowned for his very low head position when racing for the line. Usually for the win. The downside to that sort of aggressive position is that the top of the frame on most cycling glasses obscures your line of sight, and the result is usually a sore neck from craning to see under or over the frame.

With the Jawbreakers, Oakley sought to increase the upward field of view. The result is that the top of the frame is much higher than most other eyewear I have ever tested. There's very little intrusion into your vision. It's very impressive. Get your chin down on the stem and assume an aggressive position, as you would when racing or time trialling, and the top of the frame really doesn't intrude into your vision at all.

It's when you go back to a regular pair of glasses that the enormity of the difference really makes you realise how good the Jawbreakers are. I was sceptical when I first started testing the Jawbreakers, quick to write them off as a gimmick. Several months later, and I've not been wearing any other eyewear.

Not only has Oakley developed the new frame, but it has also introduced the new Prizm Road lens. It's a lens developed for road cycling and designed to deal with the changeable light conditions. It noticeably boosts contrast, making it easier to read the road surface in varying levels of light such as when dropping into a dimly lit tree-lined lane.

The lens is easily changed too, and there's a wide range of tints. To make changing lenses easy, Oakley's Switchlock is a ball joint mechanism that hinges the frame apart, allowing the lens to be easily removed and swapped for another.

The glasses are very comfortable. The arms are adjustable and they're a bit shorter and flatter than the Radars, meaning they're more compatible with the retention devices on most helmets I've tested them with. They place no noticeable pressure on the temples yet they don't move about, even when sweat is dripping off your face. The nose-pieces keep the glasses comfortably snug on your face.

The only downside I've really found with the Jawbreakers is that they tend to collect pools of sweat rather excessively. But the lenses are vented, which does prevent them steaming up.

Yes they're expensive but the fit, comfort, field of vision and high lens quality are good counter arguments. If you think they're expensive, you're not going to buy them, but the high price clearly hasn't put a lot of cyclists off investing in them.
