Guide to Fuse Lenses: A Complete Guide to Fuse

Who We Are

Fuse was founded in 2011 by two optical experts dedicated to crafting high quality lenses for sunglasses when they noticed a lack of replacement options. Since then Fuse has grown to creating lenses, frames, and accessories for eyewear fans and connoisseurs alike. Using optical grade-polycarbonate materials, we custom cut lenses to fit unique and name brand glasses.

Over the years, we’ve grown not only our products, but also our community of athletes, advocates, and trusted Fuse partners. We know your sunglasses get beat up - dropped, sat on, and taken into the harshest elements - and they don’t always stand up to the challenge. That’s why we continuously work to develop stronger scratch resistance, more durable coatings, and crisper optics. We want to not only provide the vision you expect for your high quality frames, but also become a trusted partner in all of your everyday adventures. Wanna meet the team behind fuse?

How it Works

Lenses For Any Frame

Here at Fuse, we make finding lenses to fit your needs, and favorite frames simple. To get started head to fuselenses.com, select your brand and model, customize your lenses with polarization and 20 + finish options (even prescription), then we custom cut and ship them your way.

Not sure what frames you have? Check out our guide to identifying your frames here. Still don’t see your frames listed on our site? Try our custom program that lets us do the work for you. That’s right, after you send them in, we trace your frames, custom cut and replace the lenses, then send them back to you ready to wear. It just doesn’t get any easier than that.


Your vision is constantly changing and with replacement lenses it’s easy to update your glasses as often as your prescription. Replacement lenses begin at $129 – and the best part? We accept FSA or HSA and have installment pay options. Even our Rx lenses are covered by a 1 year, 1-time replacement warranty that covers manufacturer defects to keep you on the go no matter what.

Fuse Lenses Replacement Lens Options

Whether your lenses are damaged, or you’re just ready for something new, we have lenses crafted with your needs in mind.

   Lens Colors

     Mirrored Lenses

Mirrored styles like cascade provide a sharp visual field while keeping your eyes protected.

Often uniquely and brilliantly colored, mirrored lenses are a popular choice for outdoor activities. Mirrored sunglasses contain a reflective flash coating on the lens that can help to reflect anywhere from 10 - 60% of ultraviolet rays. Our traditional mirrored lenses (like the styles glacier and sapphire) offer a distinct and sharp mirrored appearance, while our “flash” styles (like Midnight and carbon) offer a subtle reflective layer. Because mirrored lenses reduce glare and sunrays greatly, eye health is improved and damage is reduced greatly. To give you the best of both worlds, we offer polarized, mirrored lenses that maximize your lenses’ functionality.

 Tinted  (non-mirrored) Lenses

It can be confusing for anyone short of sunglass aficionado status to know what lenses might be right for them. With non-mirrored options for cloudy weather, outdoor sports, and snow, it can be hard to tell which are perfect for your daily life. When deciding on non-mirrored lenses, be sure to keep these differences of each in mind:

A grey tint is the darkest tint and can aid you in cutting glare. Grey is a versatile color and can be used in a broad range of activities and weather conditions, all while offering true color perception. Wear these lenses for everything from walking your dog to hitting the slopes. Most of our mirror-coated lenses are on a grey base for maximum versatility!

G15, better known as green lenses were developed as a prime choice for aviators and they are still on top today! These lenses offer even color perception, which helps to keep color distortion at a minimum. They also improve contrast between green and brown, which can help with reads of greens and fairways, making them a top choice for golfers too!

A brown tint is one of the most popular tints for sunglasses on the market. This lens helps to heighten contrast and improve depth perception, especially on sunny days. It is optimal for a variety of outdoor activities including inshore fishing, golf, boating and more!

Yellow tinted lens can offer greater clarity in fog, haze, and other low-light conditions. The tint can increase visibility and improve depth perception. Often, yellow lenses are preferred for indoor uses, for electronic devices, or to increase accuracy in sports. Yellow can improve your game from archery to a round of tennis.

   Blue Light

Blue light glasses are perfect for stopping digital eyestrain in its tracks.

Plugging away on your laptop can cause major digital eyestrain that can be alleviated by adding blue light glasses to your routine. These clear but stylish lenses filter out high-energy blue light that can cause migraines, dry eyes, and light sensitivity. Healthy eyes can mean increased productivity, more restful sleep, and a reduced chance of long term side effects. Here at Fuse, we offer custom replacement blue light lenses that easily pop in and out of your existing glasses so you don’t have to give up your favorite frames. For even more ways to combat digital eyestrain before it starts, be sure to check out our blog post.


When you think of transition lenses you probably think of their convenience and functionality. Photochromic options have come a long way from their single-color gray tint, and now there are a variety of colors and styles that are as fashionable as they are functional.

Photochromic lenses or light-transition lenses have a built-in coating that activates when exposed to UV light from the sun. This coating automatically adjust its tint based on the amount of light being taken in, allowing the lenses to act as a hybrid between both clear and sunglasses. Did you know photochromic lenses are available without prescription? Our non-prescription photochromic lenses block blue light, so their base color is like slightly yellow, not 100% clear.

For a busy lifestyle, having a single pair of glasses that can keep up is ideal when carrying around multiple pairs isn’t. For a fraction of the cost of a pair of glasses and a pair of shades, you’re able to have one pair with equal functionality.


If you love fishing, skiing, or any other outdoor activity, a pair of polarized sunglasses is essential. Polarized lenses have a filter in them that blocks glare where regular sunglasses don’t. Polarized lenses have a base tint that looks a bit grey giving everything a bright and vivid effect. Polarization works much like blinds, blocking all horizontal light and only allowing vertical light. That helps to reduce glare on roads, on slopes, and out on the great blue sea.

While regular polarized sunglasses tend to always cost more because of the benefits they offer - reduce eye strain, reduce glare and protect your eyes. At Fuse though high quality polarized lenses that start at 30 dollars. We can reuse and repurpose your existing awesome frames that you’ve come to love so much and that you already know you look good in.

 Fuse +Plus

You may know that our customization experience applies to tints, but did you know it also applies to coatings?  While our standard, non-polarized lenses block 100% of harmful UV light and are made from Polycarbonate, we offer two additional coatings that feature even more. Finally, Fuse +Plus Polarized + Anti-Reflective Coating lenses have all the benefits of standard and polarized lenses plus our Clear Guard hydro-oleophobic coating for easy cleaning, an Ion backside Anti-Reflective coating to block distracting light, and a stronger Fuse Force hard coating for up to 2.6 times more scratch resistance than our other lenses.

Replacement lenses are our specialty, and replacing old lenses is simple and can be done in a matter of seconds. Begin at the nasal corner of the lens on the backside of the frame.
