The HindSight Edge rear cycling glasses, developed with Olympic medallist Callum Skinner, are now on sale, featuring an innovative two-part angled lens with semi-transparent mirrors. This patent-pending lens technology claims to allow cyclists to “see forwards and backwards with a simple shift of focus rather than having to turn their heads”—for both commuter safety and a performance advantage in racing.
The HindSight Edge glasses were launched in a Kickstarter campaign last year, as we reported here, and it turned out to be a very successful one, raising more than £100,000 from over 600 backers in 38 countries.
Invented by physicist Alex Macdonald and developed with Rio 2016 Olympic gold medal-winning cyclist Callum Skinner, these glasses have been designed by optical engineer Bob Henderson.
“The team created a mathematical model based on cyclists, looking at head rotation rates, metrics such as average interpupillary distance and optimal range of eye movement, using the widely recognised Gullstrand model of the human eye,” says HindSight.
The glasses are designed to be a more stylish and functional solution for rear vision over rear-view mirrors that can be mounted on helmets or handlebars.
As well as helping to make commuter cyclists safer, HindSight says the glasses can benefit professional cyclists by giving them a “performance edge by allowing them to see competitors without losing crucial seconds by looking back over their shoulders”—which is why the brand has worked so closely with track sprinter Skinner.
Skinner notes: “Managing aerodynamic profile is essential for any elite cyclist, and by turning back to look over your shoulder you can easily lose efficiencies in your speed and performance.”
The innovative glasses have won a series of entrepreneurial development awards in 2020 including the Scottish Edge Award, the Scottish Enterprise Unlocking Ambition program, and the Allia Business Impact Accelerator fellowship.
There are three models available, starting at £199.99 for the HindSight Edge Sport, currently available at a discounted pre-order price of £174.99.

Anna has been hooked on bikes ever since her youthful beginnings at Hillingdon Cycle Circuit. As an avid road and track racer, she reached the heady heights of a ProCyclingStats profile before leaving for university. Having now completed an MA in Multimedia Journalism, she’s hoping to add some (more successful) results. Although her greatest wish is for the broader acceptance of wearing funky cycling socks over the top of leg warmers.
I came here to see if I could replace my handlebar end mirror with a set of these, but that price is way too steep. For that money, I'd want a HUD with stats and a rear view camera.
I've used a mirror that clips to my glasses arms for many years, and even though it is well outside of the arms, I still have to move my head slightly to see what is behind. I don't understand how these glasses can work without significantly moving your head, which kind of defeats the object doesn't it?
Maybe that's where the physicist comes in. The arms are made of neutron star, so the gravitational lensing allows you to see round the back of your head, because it warps spacetime.

Thanks, I knew there had to be a good scientific reason.

They are having a bit of a giraffe with that price tag.
I wish them luck while i stick to my bolle's

"without losing crucial seconds by looking back over their shoulders”
Would love to see the science behind the claim that one can lose "seconds" by glancing over one's shoulder.
"Specially formulated for consumers with abnormally large heads."
Maybe he means when racing and not your average roadie/commuter.
I was going to suggest by avoiding coming out of an aero tuck; but your rear view would be at 135 degrees?!?

lol, absolute tat. Standard kickstarter...
Invented by a physicist? Really? My kids had some a few Christmases ago, £3.95. They didn't have the word 'Sport' on though .

Ouch! Those are actually painfully similar!
