Our Product

The Sunglass Fix made a decision early on to produce our lenses out of an optical grade polyamide for a wide variety of reasons. Our polyamide lenses are far lighter, more flexible, nearly impossible to shatter, safer to handle, as scratch resistant and as clear as a glass lenses. All of our lenses meet the AS/NZS 1067:2003 standards and all other known regional quality and safety standards. They provide 100% UV protection so you know your eyes are being protected.


SFx Diamond: Our Diamond range represent the pinnacle of sunglass lens technology and optical excellence. Every Diamond lens is manufactured from optical grade polyamide – an incredibly durable material with the clarity of glass. All have an exclusive Anti-Reflective (AR) coating on the inside to reduce bounce back and an ultra-tough outer hardcoat, to help with scratch prevention. Whether classic Onyx black, Burnt Umber brown, or our new G15 gradient lines, this exclusive range has a lens to compliment your frame with technical specifications and performance to match. If nothing but the best will do, you simply can’t do better than our SFx Diamond lens.


SFx Ultra: These are one of the strongest, lightweight and durable lenses made. All SFx Ultra lenses integrate a Japanese polarization film with 99.9% efficacy rating - making it one of the best anti-glare lenses available. SFx Ultra lenses are available in a wide variety of tints, gradients and both subtle (flash) or solid mirroring. These polarized lenses are the definition of style and function.


SFx Edge: Safe, durable, lightweight with crystal clear HD performance. These non-polarized lenses are coated with a protective layer that resists scratching and repels water & sweat. All SFx Edge Lenses are made from a unique, flexible polymer that has unbelievable optical clarity. In fact, laboratory testing ranks our lenses with glass - but ours are a third of the weight, don't break, are safer and easier to install.

The Sunglass Fix does not work with glass lenses.

Cleaning:

  • Clean lenses daily: Give your lenses a careful wipe every time you put them on. It’s the surest way to keep them looking good and performing their best. First quickly blow off any dust & dirt.
     
  • Lens cloth only: If possible, only use the microfiber cloth or pouch that they came with or the one we supply. A soft, clean cloth will also do. But don’t use paper towel or tissue...these are like sandpaper to a lens.
     
  • Warm soapy water: When the smudges are bad you can use a specialist lens solutions or spray, but we recommend warm soapy water. Washing up liquid works a treat – but check there’s no added moisturizer.

     

Storage:

  • Use your case: Lenses are generally scratch resistant, they’re not scratch-proof. So, keeping them in their original case or pouch is definitely the best way to avoid damage when they aren’t on your head.
     
  • Up side down: Scratches very seldom happen to your shades while you’re wearing them. But, when you do put them down, try to ensure you place them upside down with the arms wide open.
     
  • Clean before storing: To ensure that your sunglass lenses do not determinate while you are not wearing them, its best to clean your lenses and sunglass frames before you store them for an the winter time.

     

Additional:

  • Check the screws: If your sunglasses have screws, check them with an optical screwdriver to ensure they’re tight. The arms should open easily, but shouldn’t unfold under their own weight. And if none of the tips above are working for you, don’t throw your favorite shades away. Simply fit a pair of high quality replacement lenses from Sunglass Fix and get that brand new feeling all over again.
     
  • Keep out of direct sunlight and heat: While sunglass lenses and frames are designed to be in direct sunlight, doing so on a regular basis all day can determinate lenses causing visual defects. This effect is exaggerated if the lenses and frames are dirty or wet.

Full frame: The best way to uninstall the original sunglass lenses is to find the thinnest or straightest section of the frame to begin from. The lenses should be removed by pushing on the concave side of the lens. It can often be helpful to warm the frames up to make the plastics more pliable, and/or pull the frame away from the lens while pushing the lens out. The installation is done in a similar method in reverse, Install the most curved area of the lens first (usually the arm side), Its best to work around the frame. In most cases its best to do arm first, then the top, and finally the nose side, the rest of the lens should click into position.

 
Metal full frame: Almost all of all metal frames will have a small screw hidden behind the arm of the sunglasses. Its best to partially remove this screw to loosen the frames and make the installation process much easier. We recommend not removing it completely. Once you have loosened the frames the installation process is as simple as lining up the new replacement lenses into the frames and retightening the screw.


Half rim: To remove these lenses begin by holding the lens firmly and pushing the lens towards the arm, then pry the nose area upwards and the lens will unclip quite easily.
To install your new lenses insert the arm side (thin section) of the lens into the frames and squeeze the lens into the frames from below.

Polarized lenses are some of the higher quality lenses in the industry, these lenses have a thin layer which reduces or eliminates bouncing light, otherwise known as glare. Essentially this means that polarized lenses makes it clearer to see in almost any every day situation. Polarized lenses will reduce your eyestrain which in turn will help with irritation, fatigue, redness and headaches.

Some of the major health benefits of polarized lenses are:
Safety: On sunny days, objects in the distance often appear hazy, and nearby vehicles reflect almost blinding light. Polarized lenses eliminate those effects by blocking reflections, improving eye comfort and allowing you to drive with full eye function.

Reduce eyestrain: Squinting to gain vision clarity puts stress on the eyes, sometimes causing redness, irritation, fatigue, or headaches. Polarization can neutralize these problems, helping eyes to feel more comfortable and well-rested.

Water sports: Polarized lenses are favorites of aquatic sport enthusiasts, since polarization makes it easier to see into the water. Without polarized lenses, light reflects off the water's surface, but with their help, underwater visibility is vastly improved.

Stronger vision: Wearers of replacement polarized lenses report better perception of color and images, since they are able to perceive images crisply and clearly in any environment.
 

Testing a polarized lens:
There are several ways to test if a lens is polarized, but the simplest method is to preform the check below. This displays two polarized lenses and how they completely block all light passing though when the polarization planes are held 90 degrees from each other.

There are other ways to test if lenses are polarized such as looking through your lenses onto a digital display such as a computer monitor or TV. Please note that some displays work in the opposite way and could cause some confusion weather the polarization plane is correct.

You can read more about polarized lenses and their benefits on our blog.  

look on your inside arms for your model and size information to get correct sunglass replacement lenses

When searching for your model on our site putting in less information is better than more. We store lens information at the model level, usually the four numbers or name of your frame. We don't store all the subsequent numbers that manufacturers use.

For example a Ray Ban frame will have RB#### number of the arm. Simply type the #### numbers in our lens search engine and it will usually display a few models along with their photos.

Double checking the lens width measurement is very important. To do this find the two numbers usually written before a small square on your sunglass arm or simply measure your sunglasses as instructed below to make sure you get the right lenses for your frames.

Many brands such as Persol, Prada, and Ray Ban Sunglasses commonly use the same model number but make several different sizes. For example, the Ray Ban Aviator Large Metal sunglasses all have the model number of RB3025LM. However, they come in 3 sizes - 55mm, 58mm and 62mm wide.

Unfortunately Sunglass Fix is unable to make single mask lenses that cover both eyes. The frames must support two separate lenses. We are hoping that we will have this technology in the future but at the present time the only option we can point you to is contacting the original manufacture. If they are unable to help you please consider getting sunglasses with two lenses for your next purchase and the Sunglass Fix will keep them scratch free for years.   

Sorry, we can not make single lenses that cover both eyes.

No, we do not have any branding on our lenses.

The Sunglass Fix operates just like an optometrist. We manufacture and source premium quality sunglass lenses and shape them to fit all sunglass makes and models. We do not have any affiliation with any sunglass manufacturers. Instead, we just make great lenses for all frames like an optometrist would but at a fraction of the price.
