Today, I cycled on dark country lanes + semi-lit traffic roads, and wish I had my glasses not only because of the flying nocturnal insects, but also to help distinguishing road asperities (i.e. potholes, manhole grids) and surrounding dangers (overhang branches, running deers, etc.). I hear that polarized glass actually works.
Having just broken my cheap plastic sun shades, I am considering investing in glasses that fit the bill during sunny days, and at night too. So, anyone to recommend me a product that fulfills the following criteria ?
* unbreakable frame (well...flexible and virtually indestructible is good enough )
* polarized glass (to avoid night-time reflections of car headlights on wet roads)
* photochromic (to adapt between bright-dark transitions)
* under 50 GBP (ok, I might be a tad optimistic with this one ! )
Thank you very much.
