Selecting the Perfect Sunglass Lens Material


Sunglasses are your go-to defense against the sun's harmful UV rays. But to maximize their effectiveness, it's crucial to opt for the right lens material. Each material brings its own set of advantages, so let's explore your options.


What are the Different Types of Sunglass Lens Materials?




Polyamide stands out as the top-tier option for sunglass lenses – and it's our preferred pick at Sunglass Fix. While pricier than glass, it boasts near-identical optical clarity. Plus, it's shatterproof and flexible enough for hassle-free self-installation into your favorite frames.




Glass stands out as one of the top-tier materials for sunglass lenses. It excels in refracting light, offering unparalleled optical quality. With exceptional scratch resistance and superior UV light filtration, glass provides an unbeatable visual experience. However, it's worth noting that glass lenses are heavier, pricier, and more prone to cracking compared to other options.




Polycarbonate lenses strike a balance between durability and clarity. Renowned for their impact resistance and clear vision, polycarbonate lenses are the go-to choice for safety, sports, and children's eyewear. While polarized polycarbonate lenses offer lightweight comfort and affordability, they may not be as scratch-resistant as other materials.


AC Lenses


Looking for a budget-friendly alternative to polycarbonate? Enter acrylic lenses, ideal for those moments of occasional or casual sunglass wear. While they offer a cost-effective option, it's essential to note that acrylic lenses may not match the optical clarity of glass or polycarbonate. Additionally, some image distortion might occur.




CR-39 lenses have been a staple since their inception in 1947. Renowned for affordability and superb optical clarity, they're resistant to radiation, aging, material fatigue, and chemicals. Plus, they're less likely to shatter, making them a durable choice. With the added benefit of being lightweight and easily tinted, CR-39 polarized lenses are a versatile pick for any sunglass enthusiast.


What to Consider




Size matters when it comes to sunglass lenses. Opt for larger frames for increased UV protection, but don't sacrifice comfort. Find the right fit to ensure you can wear your sunglasses comfortably, whether you're working outdoors or hitting the sports field under the sun.




Quality sunglasses are essential for lasting protection. Consider replacing them every two years to maintain optimal UV defense. Though they may be pricier, investing in quality shades pays off with durability and scratch resistance.




Choosing the right sunglass material isn't just about protection – it's about comfort too. Find a material that fits your face shape snugly and caters to your lifestyle needs. Whether you prioritize contrast enhancement or maximum outdoor protection, selecting the perfect lens material ensures both comfort and functionality.


Lens Color


Sunglass lenses offer a spectrum of color options, from solid tints to gradient shades like brown, gray, or green. While color doesn't affect UV protection, it does influence visual contrast. Certain hues enhance contrasts, making them ideal for athletes in sports like swimming, golf, and baseball. Choose a lens color that suits your outdoor activities and enhances your performance.


Evaluating Lens Quality


When selecting sunglass lenses, quality is paramount. Look for lenses with a uniform tint rather than overly dark ones. Before buying, hold the lenses at arm's length and inspect them for imperfections. Move them slowly along a straight line – any defects will cause the straight edge to sway or distort. Remember, low-quality lenses provide minimal UV protection and offer little benefit over not wearing sunglasses at all. Choose wisely for optimal eye protection.
