Right here’s what I prioritized when deciding which sun shades to check and what I seemed for throughout our testing:
Protection: The extra curvature that sports activities sun shades have, the extra safety they supply. “Base curve,” “wrap,” and “bend” are all phrases used to explain lens curvature. I examined fashions marketed as having base curves starting from 6 to 10; I most popular fashions with a 7 or 8, for his or her steadiness of safety, versatile styling, and prescription compatibility.
Fog resistance: Some sun shades worth safety over breathability, which can make them extra susceptible to fogging throughout vigorous actions—particularly while you cease transferring, which reduces airflow. Most high-quality sun shades have an anti-fog coating, however it’s laborious to stop fogging if the sun shades are very near your face. I seemed for sun shades that steadiness protection with airflow.
Match: I seemed for sun shades that are available a couple of measurement. I additionally seemed for adjustable sun shades, that means that I may alter the temples completely by bending them or swap the nosepieces to alter how the bridge matches. If the temples weren’t adjustable, I examined their flexibility—in search of temples that’d unfold sufficient to suit comfortably.
Weight: Until you’re knowledgeable athlete, the load of your gear often shouldn’t be an enormous concern. Nonetheless, whereas testing sun shades—typically for 12 hours at a time—I did discover which pairs had been lighter and which had been heavier. (Our picks vary in weight from 24 to 33 grams.)
Sturdiness: I sat on every of the sun shades I examined, pressed their nosepieces to the temples, flexed the temples in reverse instructions, and threw them throughout my workplace on the wall or onto a tough flooring. I additionally by accident dropped a number of pairs whereas operating (when eradicating them to wipe away sweat) and whereas ski touring (when altering from sun shades to goggles). All of our picks got here by these exams admirably. Nonetheless, I additionally prioritized sun shades with replaceable components—together with lenses, temples, and nostril pads.
Lens high quality: When transferring quick, you need sharp optical high quality; that’s, no eyestrain and the power to see particulars clearly whereas in movement. Most sport sun shades lenses are manufactured from polycarbonate, a robust plastic proof against shattering that additionally has nice optics, particularly when lenses are preshaped in a mildew, which most high-quality lenses are. Our runner-up decide and our price range decide each use polycarbonate lenses; our prime double-lens decide makes use of polycarbonate lenses in its cheaper lens choices.
Trivex is a fair stronger materials with an edge in optic high quality over polycarbonate; it’s offered underneath just a few different model names as properly (NXT, Phoenix, and Trilogy). The Rudy Challenge Rydon’s pricier lenses are manufactured from Trivex (the corporate’s proprietary identify for it’s ImpactX). The fabric is usually dearer than polycarbonate.
Nylon (typically known as polyamide) additionally offers wonderful optics—higher than polycarbonate and shut in high quality to Trivex. Our prime shield-style decide has nylon lenses. Very light-weight and versatile, nylon isn’t rated as being as impact-resistant as polycarbonate and Trivex, however it’s robust sufficient for sport use.
The most affordable lenses we’ve seen are sometimes manufactured from primary plastic or acetate plastic, which is lower from a sheet, then bent to form. Such lenses are virtually positive to trigger eyestrain over time. “They may appear fuzzy, soiled, or foggy, however they’re not,” stated SportRx’s Rob Tavakoli. “They’re simply not good lenses.”
Lens darkness and tint: I seemed for sun shades that are available a wide-enough number of darknesses and tints that most individuals will have the ability to discover a lens that’ll work for them.
Lens darkness is measured in variable mild transmission, or VLT. The next VLT means much less mild for shiny days, and a decrease quantity means extra mild for darker days. By tint, I imply base tint—what you see from the within of the lens. Coatings and mirrors can alter a lens’s exterior look, however it’s the within that counts.
Because you would possibly want completely different lenses for various situations, I additionally seemed for sun shades with lenses you possibly can swap out (and examined to see how simple it was to take action).
Prescription compatibility: Not each pair of sports activities sun shades is prescription-ready. It’s difficult to construct a prescription into lenses as curved as these you discover on sports activities sun shades. “A heavy wrap in even a low Rx goes to trigger some issues,” stated John Seegers, optician and founding father of OpticianWorks, who can be a leisure bike owner and mountain climber. “Because the Rx energy goes up, so will the distortion.”
Protect sun shades are even much less properly suited than double-lens sports activities sun shades for individuals who want correction. It is because prescriptions are made for every eye, and constructing in two prescriptions into one lens is tough, particularly because the prescription will get stronger.
When you’ve got a robust prescription—usually, this implies prescriptions of +/- 4 energy or extra—you’ll seemingly want double-lens model sun shades, whose lenses might be individually dialed in to suit your prescription.
Availability and return coverage: A few of the sun shades we examined can be found solely on-line, whereas others are stocked in shops. For these which might be out there solely on-line, we prioritized these with good return insurance policies.
