The dhb Photochromatic Half Frame Sunglasses offer decent performance in a variety of conditions without looking obviously technical or breaking the bank. I am also pleased to report that I found them very comfortable worn for long periods.
The lenses are made from shatterproof, scratch-resistant polycarbonate and feature a filter category 3, which is heavily tinted and an obvious choice for strong sunlight, with a mirror finish that serves to subvert glare when riding in direct sunlight or when it's being reflected along wet roads. They also, according to dhb, provide 100% UVA and UVB protection.
The photochromatic technology works very well for the most part: they react better to subtle changes in light than sudden and extreme changes such as harsh morning/evening sun, and though they're not as quick-reacting as much more expensive models I've used, such as Shimano's S-Phyre Rs (£129.99) and Julbo's Aerospeeds (£135), I wouldn't consider it a deal-breaker considering their price.
Around dusk, they handle the steady, incremental darkness surprisingly well and they've never given a misleading view of surfaces, or conditions ahead – optical clarity has remained consistently good. To date, I've not needed to remove them in very low light.
The hydrophobic coating is good, too – rain, drizzle and muddy spatter beads up and slides away, if, again, not as quickly as on more expensive models.
They're not as big as some in my collection, but I'm pleased to report I've had no issues with rain, wind, dirt or grit sneaking past.
I have experienced some minor misting, but this was cured by adjusting the glasses' position and moving them away from my face.
Fit/comfort
The matt black frames feature silicone grippers to ensure slip-free tenure around the ears, and a rubberised nosepiece to keep them unobtrusively in place. I find myself broadly compatible with most off-the-peg shades, though these are a looser fit than some around the nose; it felt disconcerting to start with, but there's been no annoying slip while road riding.
The arms are less tenacious than some designs, but have gone unnoticed, with no hint of discomfort even on day rides, keeping the glasses exactly where I've wanted them.
Off-road, they tended to bounce around a little – worth noting if you're fond of mixed terrain riding or take towpath cut-throughs on your commute – but they are geared towards road riding.
Durability
The glasses have taken some direct hits – smaller stones flicked up by large vehicles – without showing any signs of superficial let alone more serious damage.
Though slightly flexy feeling, the frames have stood up to the usual, everyday carelessness so there's no reason to think they would fail under normal use.
Value
There's not much to rival these at this price, specification-wise. If you don't mind a trail flavour, then the RockRider XC Race Photochromic sunglasses might give them a run for your hard-earned. They're almost a fiver more but come with a good spec and a two-year warranty.
A few quid more buys you BBB's BSG-58PH Impress photochromic glasses for £54.95, which boast UV 1, 2 and 3 category protection. The lenses automatically shift between 85 and 17% light transmission depending on the brightness.

Otherwise, the dhb Photochromics offer a lot of bang for very little buck. They also come with a compact softshell carry case.
Verdict
Impressive glasses for most conditions and road-biased riding, with only some minor compromises

They are shatter-proof and scratch-resistant to make them highly impact resistant against debris which may flick up from the road whilst out riding. A mirror finish eliminates glare from the sun which proves advantageous when riding in sunlight on wet roads or into direct sunlight.

A rubber nose gripper helps keep the sunglasses in place. A hydrophobic coating is featured on the inner and outer lense which helps to repel sweat and water in intense training sessions. The matt black frame is lightweight for added comfort and is finished with subtle dhb styling.

Tell us how the product performed overall when used for its designed purpose
Overall performance has been very impressive. The hydrophobic coating lacks the water shedding prowess of some and the lenses don't react at the same speed or cope with sudden and extreme changes in light as much higher-end models, but this isn't problematic in the everyday sense, and are compromises I would expect given the price point. If you are looking for a single set of glasses for bike and general wear, they're good value.
Tell us what you particularly liked about the product
Nice styling, comfortable to wear and generally decent optics.
Tell us what you particularly disliked about the product
Not much when everything's taken into account but being picky, the looser fit meant more frequent adjustment when tackling unmade roads.

can anybody with experience of both comment on the pros/cons of photochromic vs polarising. I've never used photochromic, but I like how polarising lenses selectively cut glare off the road from a low sun.
Photochromic cycling glasses (with prescription lenses) are the best thing I've ever bought for on-bike comfort.
If yours is a negative dioptre (short sight) prescription, where did you get them please?
Yes, agreed, my Rudy Rydon's were supplied by Extreme Eyewear with prescription lenses - they recalibrate the prescription to suit the high curve on the lenses. Excellent service.
These look very similar to my classic Rudy Rydon's.
Wiggle site saying 45 - 17%, seems a bit of a limited range to me.
If these are photchromic and get to category 3, what is the range? What is the minimum light reduction ?
