A road.cc review found that Povec’s C1 Performance Sunglasses can switch between a lighter Cat 2 tint and a darker Cat 3 tint in roughly one to three seconds. The reviewer said the quick adjustment is useful when riding through changing light, but noted the £249 price, some lens artefacts and limited suitability for very low light.
Road.cc has reviewed Povec’s C1 Performance Sunglasses, cycling eyewear that uses an electrochromic lens layer to switch from a lighter Cat 2 tint to a darker Cat 3 tint. The reviewer found the change took about one second when lightening and two to three seconds when darkening, offering riders a faster way to respond to sudden changes in light than conventional photochromic lenses, though the glasses cost £249.
The C1s are half-frame riding glasses with a yellow-mirror lens and black frame; other lens and hardware colour combinations are available, according to the review. They weigh 40 grams. A small battery in the frame powers an electrochromic layer inside the lens. Opening the arms switches on the system, and swiping the logo on either arm changes the tint. A covered USB-C port is used for charging.
The reviewer said the glasses move from dark to light in about one second, while the change from light to dark takes roughly two to three seconds. Povec’s stated claim, quoted in the review, is that riders can “Choose the right tint level in under 1 second.” The reviewer found that description broadly accurate for lightening, but not for darkening. The review compares this with a wait of around 30 to 60 seconds for photochromic lenses to adjust.
On test rides, the reviewer used the lighter setting before entering dense tree cover and on rides affected by clouds or passing showers. The lens offered a wide field of vision and was described as clear and distortion-free across most of its area. The reviewer also reported occasional artefacts and colour fringing around bright light sources, which they attributed to light reflecting within the lens’s layered construction. The lens repelled water, and the review cited an IP65 ingress rating; the battery life is stated by the manufacturer as up to 28 days, based on four hours of use daily.
Rapid Tint Changes on the Road
The review’s main finding is that the C1 offers a practical way to change tint while riding, rather than waiting for changing conditions to affect a photochromic lens. That could help riders moving between bright roads and shaded sections, or setting out in dim morning light as the day brightens. The reviewer said being able to lighten the lens ahead of dense tree cover made it easier to see than staying in a dark tint.
The feature comes with trade-offs. At £249, the glasses cost substantially more than the lower-priced photochromic examples mentioned in the review, and they do not cover every lighting condition. The reviewer found the lighter setting only just adequate in darkness, while the lens’s minor optical artefacts were more apparent in low light. The product may suit riders who value quick manual control, but the review does not establish that it is a better choice for all riders or conditions.

How the C1 Tint System Works
Photochromic lenses change tint in response to light, but the review says they can take 30 to 60 seconds to adjust. The C1 uses an electrically controlled layer instead: riders activate a tint change with a swipe on the arm of the glasses. This is not a continuously automatic adjustment; it is a manual change between two tint levels, as described in the review.

The supplied material does not include a separate product launch date, additional laboratory measurements or comparative testing against other electrochromic eyewear.
““Choose the right tint level in under 1 second.””

Limits of the Review Evidence
The findings describe one reviewer’s testing; the supplied report does not give the length of the test period, a full battery-life test or laboratory measurements of tint transmission and optical distortion. Battery life of 28 days is a manufacturer claim based on four hours of daily use, rather than a result independently verified in the review.
The review does not establish how the glasses perform across every face shape, riding discipline or weather condition, nor does it provide a direct comparison with another electrochromic model. It also does not specify the product’s current availability or whether the listed £249 price has changed since publication. The reviewer’s assessment of low-light performance is qualitative, not a measured safety finding.
What Riders Should Check
Readers considering the C1 can compare its two tint settings and manual swipe control with the slower, light-responsive operation of photochromic glasses. The review suggests paying particular attention to low-light use and lens clarity, since those were the main limitations reported by the tester. Riders should also check the current price, fit and product specifications with a retailer before buying; the supplied source does not say whether Povec has announced revisions or a successor model.
Key Questions
How quickly do the Povec C1 lenses change tint?
Road.cc reported that switching from dark to light takes about one second. Going from light to dark took the reviewer about two to three seconds.
What tint levels does the C1 offer?
The review describes a lighter Cat 2 setting and a darker Cat 3 setting, selected by swiping the logo on either arm.
How much do the Povec C1 sunglasses cost?
The review lists a price of £249. The supplied report does not confirm whether that price remains current.
Are the C1 glasses suitable for very low light?
The reviewer said the lighter lens was only just adequate in darkness and that lens clarity issues were more noticeable in low light. That is the tester’s assessment, not a formal safety certification.
How long does the battery last?
Povec’s stated battery life is 28 days, based on four hours of use per day. The review says the tester had not needed to recharge after the initial charge, but does not report a complete battery-life test.
