Oakley Flak Beta – Top Performance Sunglasses


Oakley is a world leader in the field of sports eyewear.

They’ve been trusted by elite athletes in a multitude of different sporting professions for a simple reason:

Oakley continuously delivers high-tech sunglasses that deliver sturdy protection and clear optics thanks to their highly innovative approach.

Simply put, these guys make some of the best sunglasses on the planet.

Oakley has a stirring passion to reinvent. This devotion to creating with leading-tech in mind has produced some great results.

Amongst these results are technologies like High Definition Optics, Impact Protection, Switch Lock, and True Digital Edge.

What this all means for you, the consumer, is that you’re getting the highest quality, most innovative protective-sunglasses on the market today.

Of particular intrigue is their Prizm tech which is ‘a revolution in lens optics built on decades of colour science research’.

You’re able to purchase a pair of Oakley Flak Beta sunglasses with the Prizm lenses.

What this gives you is automatic light transmission control resulting in colours precisely tuned to maximize contrast and enhance visibility.

All in all, active users of these sunglasses adore the advanced lens features, solidly built form-factor, and protective quality.

Let’s jump into the details.

Buy the Right Pair of Flak Beta Sunglasses

Smith MAG Technology

First up, we have the Grey Lens pair.

They come equipped with a matte black frame and grey lens.

These sunglasses come with most of the innovative technologies that Oakley has developed with the notable exception of Oakley’s Prizm lens tech.

This is reserved for the more sports-oriented sunglasses – namely the Golf Prizm and the Trail Prizm which we’ll look at next – but your eye protection needs may very well be adequately served by a pair of the Flak Beta Grey Lens sunglasses.

Next, as mentioned a moment before, are the more sports-oriented Oakley Beta’s.

They come equipped with Oakley’s Prizm lens tech (explained further in the article) meaning you’re getting sunglasses that enhance colour and contrast for more accurate vision.

To play golf well, you have to do more than just read the green.

You need to spot the transitions between the fairway, fringe, and rough. You have to gauge distance with accuracy, and you need a good eye for grass textures.

The Oakley Flak Beta Prizm Golf lenses help golfers with all these things and more.

The separation of colours gives you more depth cues to gauge distance for wedge shots.

What’s more, when you’re on the green, you can easily differentiate grass conditions and grain direction to predict ball speed.

Simply put, having a pair of these on your face provides the very real possibility of reducing your handicap.

Sounds like an essential tool to add to your golf-mastery toolbox.

In a similar vein, the Oakley Flak Beta Prizm Trail lenses may make you a better runner.

By offering clearer differentiation in the running surface, you have a lower risk of inadvertent injury as you’ll be able to spot that puddle of water for what it really is – an ankle-jarring pothole.

It seems only sensible to allow yourself the opportunity to finish a race (or casual Saturday morning run) injury- and stress-free, every time.

The Prizm tech dramatically improves your chances of being a better golfer and/or a less injury-prone runner.

So, in short, you’re probably better off purchasing a pair of Flak Beta’s that come with the Prizm lenses from the start.


There are many sunglasses on the market that tend to partially block your vision with the frame.

This can be quite the impediment where you need completely unobstructed vision in your sporting activities.

The Oakley Flak Beta sunglasses have optimized peripheral vision and side protection of 8.75 base lens curvature.

This means that the coverage of these sunglasses offer not just an undistracted view of the surrounding environment but also serve as a layer of protection from side-entering debris


Comfort is a priority for sunglasses used in sports and general outdoor settings.

Perspiration, dust, and sharp movement can all disturb the general comfort of other sunglasses on the market but not the Oakley Flak Betas.

They guarantee all-day and all-condition comfort with a couple of key technologies built into the glasses.

Unobtainium™ earsocks and nose pads keep these glasses in place and have a clever increased grip in the presence of perspiration.

The stress-resistant frame material, O-Matter™, is lightweight and durable for all-day comfort and protection.

All this talk of “lightweight” and “all-day comfort” may leave the impression that these sunglasses lack the sturdiness and strength that may be implied by heavier sunglasses. This couldn’t be further from the truth.

Oakley performance eyewear, due to decades of innovation, offers uncompromising protection against high-velocity and high-mass impact.

The truly premium materials and unique build architecture ensure that you’re getting the best of both worlds – resilient strength and all-day comfort.

Photochromic vs. Prizm Lenses

Oakley glasses have been pioneers with their lens technology. Buy a pair of Oakley’s and you’re guaranteed to provide some top-notch protection for your eyes.

As mentioned earlier, there are two main lens variations on offer when you purchase a pair of Oakley Flight Flak Beta sunglasses: photochromatic lenses or Prizm lenses.

The photochromatic lenses on the Oakley Flak Beta sunglasses are built with Oakley HDO technology.

In short, these are optical lenses that darken on exposure to light of a sufficiently high frequency.

Imagine then that you start your run on a cloudy morning. Your photochromatic lenses will be lighter (allowing in more light), and later, when the sun peeks out in the afternoon, your lenses will automatically darken giving you more UV protection.

The key here is that the process is automatic. This saves you from swapping out one kind of lens for another when lighting changes.

Now for the Prizm lenses.

They too are built with Oakley’s High Definition Optics tech but where they differ from the photochromatic lenses is in the contrast and colour they offer.

They’re designed to specifically enhance colour and contrast.

So whether you’re golfing or running, you’re guaranteed to pick up environmental details that you were previously unaware of.

The Prizm lenses on offer by Oakley are served in a variety of colours which each have unique colour filtering features such as the Prizm Golf and the Prizm Trail.

Style and Aesthetics

While aesthetics may not be your number one priority when you purchase sports sunglasses, the Oakley Flak Beta sunglasses strike a neat balance between utility and aesthetic.

You’ll find, for example, that the more subtle matte black frame and grey lens may be suitable for the days where you need something for your morning run and afternoon braai with friends.

They will serve your purposes very well on a larger number of applications, aesthetically speaking, than the Flak Betas equipped with the more visually striking Prizm lenses.

However, if you’re looking for all the fantastic benefits of the Prizm technology, then you may need to forgo social style in favour of the Prizm Golf or Prizm Trail lenses.

While you definitely won’t be attending your next business meeting sporting either of the lens variations, you best believe that you’ll be looking your performance-optimized best for the next tee-off or Run Club.

Buying Oakley Flak Sunglasses in South Africa

Although Oakley Flak Beta sunglasses are available in several brick-and-mortar stores nationwide, Oakley doesn’t have a store finder in South Africa, making it hard to find a specific store that carries it.

The good news is that Oakley has online-based authorized resellers that sell authentic Oakley sunglasses.

Oculux is an authorized reseller of Oakley, Rayban, Arnette, and Vogue Eyewear online and has made over 11,000 customers happy over the years.
