Sunglass Lens Types and Frame Materials: A QUAY Guide
Sunglass lens types fall into two groups: the material a lens is made from, such as polycarbonate or the high-index lenses used for prescriptions, and the treatment it carries, such as polarized, gradient, fade or mirrored. Frames add a third choice, since acetate, metal and injection frames each wear differently. This guide gives you the short answer for each, then points you to the Quay page that goes deeper.

What Are the Main Sunglass Lens Types?
The main sunglass lens types are solid tinted, gradient or fade, polarized, mirrored and photochromic, and each one changes how a lens handles light in a different way. Here is how they compare at a glance.

What Is the Best Lens Material for Sunglasses?
There is no single best lens material for sunglasses, because the right one depends on how you wear them, and what protects your eyes from the sun is the UV rating, not the material or the tint. For prescription sunglasses, our store lists two lens materials:
• Polycarbonate. A 1.58 index polycarbonate lens. Thin and lightweight, they are recommended for prescriptions from +4.00 to -4.00.
• High-index. The 1.67 lenses are extra thin and lightweight, while the 1.74 lenses are ultra thin and lightweight. The 1.67 option is recommended for prescriptions from +6.00 to -6.00, while the 1.74 option is designed for stronger prescriptions of +/-6.00.
You can see every option in the prescription collection, and our guide on adding prescription lenses to sunglasses walks through how it works. For the price side, the prescription sunglass cost guide covers it.
Are Polycarbonate Lenses Good for Sunglasses?
Yes, polycarbonate lenses are a strong choice when toughness matters, with one caveat about scratches. According to the American Academy of Ophthalmology, polycarbonate plastic sunglasses, used in many sports, are especially tough, but they scratch easily, so if you buy polycarbonate lenses, look for ones with scratch-resistant coatings. Our guide on getting scratches out of sunglasses and glasses explains what to do when a lens does pick up a mark.
How Do You Choose Sunglass Lens Colors?
Sunglass lens colors are a style choice that also changes how light reaches your eyes. Our guide to sunglass lens colors owns the full breakdown, and the short version is below.
• Brown. Reduces glare and enhances the clarity of polarization.
• Black. Displays colors accurately and works on sunny days as well as in cloudy and rainy conditions.
• Green. Brightens surroundings, reduces glare and enhances color accuracy.
• Purple. Enhances color perception, especially in low light like gray cloudy skies.
To shop by color, open the black lenses, brown lenses, blue lenses, clear lenses, gold lenses, green lenses, orange lenses, pink lenses, purple lenses, red lenses, silver lenses or yellow lenses collection.
Are Mirrored Sunglasses Worth It?
Mirrored sunglasses feature a reflective coating that gives your lenses a bold, standout look while reflecting light away from your eyes. The finish is a style choice, separate from polarization and UV protection, so make sure your sunglasses offer adequate UV protection regardless of the lens finish.
Explore our mirrored lenses collection to find your look, and check out 6 reasons why mirrored sunglasses are a must-have for more style inspiration.
Polarized, UV400 or Both?
They do different jobs. Polarized lenses help reduce glare from reflective surfaces like roads, water and snow, while UV protection helps shield your eyes from harmful ultraviolet rays. Our polarized vs. non-polarized sunglasses guide breaks down the differences to help you find the right pair for your needs.
Whether they're polarized or not, all QUAY lenses block 100% of UVA and UVB rays. For more on UV protection, explore our UV400 sunglasses guide. And if you’re still weighing your options, check out our guide to whether polarized sunglasses are right for you.
Which Frame Materials Does Quay Use?
Our frames come in acetate, metal and injection constructions, and each has a distinct feel on the face.

• Acetate. Known for its durability and lightweight feel, acetate can also be dyed to create the rich colors and patterns that make each frame stand out. Check out our guide on what cellulose acetate is to learn more.
• Metal. Sleek and lightweight, metal frames offer a classic look that's made to last. Explore our metal frames collection or read more about why metal makes for perfect eyeglasses frames.
• Injection. Some styles, like TOTAL VIBE, feature premium injection frames for a different take on everyday eyewear.

If weight is your priority, our guide to lightweight sunglasses compares comfortable styles, and our durable sunglasses roundup covers frames built to last.
Frequently Asked Questions
What type of sunglass lens is best?
The best sunglass lens type is the one that fits your routine: polarized for glare from roads and water, a gradient for a lighter view below, or a solid tint for everyday wear. Whatever you choose, check the label for UV protection, because the FDA advises choosing sunglasses with a UV400 rating or 100% UV protection.
What is the best lens material for sunglasses?
It depends on how you use them. According to the American Academy of Ophthalmology, polycarbonate is especially tough but scratches easily, so look for a scratch-resistant coating. For prescriptions, Quay lists polycarbonate and high-index lenses.
What is better, UV or polarized sunglasses?
Neither replaces the other. UV protection shields your eyes from the sun, while polarization reduces glare, so look for a pair that offers the rating first and polarization where glare is your problem.
Are mirrored lenses polarized?
Not necessarily. A mirror finish is a coating on the outside of a lens, and polarization is a separate filter. Check the product page for which a style offers, and for UV, check the label.
Do nylon sunglass lenses exist at Quay?
We only name a lens material where a Quay product page states it, and our sunglasses pages do not state a nylon lens. Check the pair you are interested in.
