Tifosi Unisex Swick Single Lens Eyewear

Product Information

Category 1 lenses let in 43 to 80 per cent of light. They are regularly coloured lenses, such as bright yellow, that aim to increase contrast on cloudy days. The glasses have solid frames and a curved, face-hugging wraparound lens that mostly fills the field of vision. Peripheral vision at the sides is completely covered. The lenses have vents top and bottom and I found these to be very effective. Even on cold days, these glasses never misted up when I was moving. I occasionally got a little mist when I stopped at junctions after hard efforts on really cold days, but that cleared the instant I started to move again. The nose and temple grips keep them securely in place, no matter how lumpy the landscape I’ve been running and riding over became, and for the most part they’ve been pretty comfortable to wear for reasonably long periods of time – the hydrophilic nose grips seem to pinch slightly after while, but this can be relieved by lifting the glasses momentarily. Interchangeable and/or spare lenses such as clear night-time lenses definitely add value, but only if you actually use them, so be honest with yourself about your needs.

Comfortable to wear, the flexible and robust nylon Grilamid TR90 frame has a seemingly basic design, but the arms and nose pads keep these lightweight sunnies firmly in place no matter what you’re doing, which earns them a place in our guide to the best sunglasses available at the moment for hiking and climbing. These wraparound sports sunglasses are a different animal to the other Tifosi shades we tested, and have a higher price tag to reflect this, though still pretty reasonable. Half-lens frames mean that lenses can be swapped for different conditions, and vents prevent sweat up on hot days. Looking straight into the sunlight, the far horizon and navigation mark is still visible, thanks to the polarization. This is looking through the Oakley Leffingwell Prizm lens.Everyone’s face is different, and finding ones that fit comfortably and securely in a style that you like will take a certain amount of trying on. Most brands carry multiple styles, however, that use the same ideas and technologies to suit a range of wearers. We researched other brands and found that they were appalling quality straight out of the box and often more expensive too. The force in grams required to pull the sunglasses from the wearer’s head, using luggage scale attached to the central nose bridge When it comes to lenses, you get what you pay for on the whole, and cheaper glasses will save in this area, as well as the quality of their construction. We were surprised on both counts, however, by the cheapest pair on test from Tribord, which performed consistently well in all areas, to make it the test winner. The downside is that light from your instruments can be refracted through their screens, polarizing it parallel to the surface of the glass, so you might need to tilt your head to see the screens clearly. How we tested the best polarized sunglasses

These are a reasonable pair of shades at a reasonable price, and will serve well on and off the water, but they don’t reach the standards of the best glasses in this test. Grip on the head was reasonable but not much more than those without rubber, the grips perhaps compensating for the wider more comfortable fit. Style wise, these might not be everyone’s cup of tea, but they do their job well and would double up for other sports. Is colour more important than comfort? Is style superior to adjustability? Where can you save some cash?The weight and dimensions of each pair, including how flat or wrapped around they are, measuring the linear distance from the nose bridge to a line between the rear edge of the lenses Non-mainland deliveries are subject to courier availability and capacity and may be liable to unforeseen delays. It helps to understand what your new glasses will and won’t do. Light travels in waves. These waves oscillate along different planes – imagine waves coming at you each aligned vertically, horizontally, and all the angles between, through a full 360º. Category 2 lenses let in between 18 and 43 per cent of light, and are usually coloured in slightly darker hues, meaning they are best for days where weather is intermittently sunny.
