These inexpensive RSP Membrane glasses offer very good optics ideal for low light autumn/winter cycling and even a spot of cyclo-cross riding, only slightly let down for me by their fit.
You can spend a small fortune on cycling-specific eyewear. These Membranes prove you really don't need to. They're a simple design with a half frame construction, a one-piece curved lens and a soft rubber nose piece attached directly to the lens.
The arms have soft flexible end sections, but despite this they exerted just a bit too much pressure. After a couple of hours left me a little sore. Those with a big head might want to check the fit first. However, their tight grip does ensure they don't shift about on your face, they cling firmly to your head even on rough roads or bumpy trails on the cyclo-cross bike.
I had some compatibility issues with the Giro helmet I was testing them with, but trying a few other helmet brands reveals it seems to be an isolated issue. It's not a big concern, I'm just really fussy about how well glasses fit and interact with helmet straps and retention systems.
As a contact lens wearer, I always don cycling eyewear when cycling. At this time of year, with very low light levels common and early morning and late evening rides rendering nearly all lens tints useless, the clear lens has been a huge bonus.
You don't get a hard case to keep them in, just the clear plastic packaging they're sold in. At this price such an omission can be excused.
Inexpensive eyewear with a clear lens ideal for night-time and low light cycling.

RSP Premium Innovative Design.
Very good construction.
The fit isn't quite perfect, but that aside the optics are very good with decent coverage, an ideal choice for low light and night-time riding.
They're not supplied with a hardcase so you have to look after them carefully, on the bike durability has been just fine so far.
Yes they're very light.
The arms apply a little too much pressure to my head and on longer riders left me a bit sore.
Despite their not-quite-perfect fit, the clear lens has seen them getting a lot of use at this time of year, and because they don't cost much, you're not worried about scratching them.
