Cycling
The rear-view mirror, for the cyclist.
You wouldn't drive without a rear-view mirror. Knowing what's happening around you is the difference between operating safely and operating blind — in any environment. HINDSIGHT brings that same standard to the cyclist. Built into the lens.
The blind spot you have accepted
The shoulder check. The wobble. The close pass you didn't see.
Every cyclist has run the same loop. Hear the engine. Decide whether to look. Turn the head a quarter-second — too long. Swerve a centimetre — too far. Hold the line and hope.
The shoulder check is the cost of a missing mirror. A car has three. The cyclist has had none — until now.

None, built in. Until now.
HINDSIGHT
The rear-view mirror, built into the lens.
What the lens does for you
The HGV is in the lens before it reaches the wing mirror.
HINDSIGHT puts the rear-view in your sightline. The HGV blind spot closes. The car you couldn't hear above the wind surfaces in peripheral vision. Eyes stay forward. Line stays clean.
The data on the cost of looking back is brutal — close passes inside 50cm happen 1-2% of the time, and the shoulder check costs the same two seconds NHTSA says doubles your crash risk.
Rear-view, built in
The lens is the mirror. The mirror is the lens.
The research
139 milliseconds faster.
Tested at Edinburgh Napier University. Forward vision continues through the mirrored zone.
Research conducted at Edinburgh Napier University measured how wearers respond to hazards approaching from behind, compared to the same wearers using conventional lenses.
Reaction time to a rear hazard was 139 milliseconds faster. Forward vision continues through the mirrored zone.

Questions
In plain language.
What does HINDSIGHT do for cyclists?
Forward and rearward vision, delivered through a single semi-transparent mirrored lens. The mirrored zone is engineered into the lens surface. Forward vision continues through it. Shift focus and the rear-view appears.
Is this a replacement for a helmet or handlebar mirror?
HINDSIGHT removes the need for an accessory. The mirror is the lens. The lens is the mirror.
Does the rear view distort forward focus?
The Napier study recorded forward vision continuing through the mirrored zone while wearing the lens. The rearward image sits in the natural peripheral field, the way a wing mirror sits in a driver's.
Is there independent research?
Yes. Research conducted at Edinburgh Napier University measured 139 milliseconds faster reaction to rear hazards.
Does it have cameras or electronics?
No. HINDSIGHT is passive optics. No cameras. No batteries. No screens. The lens is the mirror.
Can I get prescription lenses?
Prescription availability depends on the certified partner product. Look for the HINDSIGHT certification on partner sites.
How does HINDSIGHT help in heavy traffic?
By placing the rear view inside the lens, HINDSIGHT lets the cyclist see the HGV, the close pass, or the approaching car without taking eyes off the road. The shoulder check that costs balance and visibility goes away.
Will HINDSIGHT replace my handlebar mirror?
Yes — for most riders. The mirrored zone in the lens sits in peripheral vision the way a wing mirror sits for a driver. No mounting, no vibration, no accessory to lose. Bar-end mirrors stay useful for very specific touring setups but lose visual lock on rough surfaces.
Does HINDSIGHT work in the rain?
Yes. The mirrored zone is engineered into the lens surface. Rain and spray on the lens reduce overall legibility the same way they do on any sunglass, but the rear-view function continues. Wipe and ride.
Are HINDSIGHT cycling glasses prescription-compatible?
Prescription availability depends on the certified partner frame. Look for the HINDSIGHT certification mark on the partner product page for current prescription options.
Key facts
What HINDSIGHT means for the cyclist.
- "Failed to look properly" is the most common contributory factor in reported cyclist collisions (UK Department for Transport).
- HGVs cause 16.8% of UK cyclist fatalities from 1.6% of collisions. The rear-view in the lens surfaces them before the cyclist could turn for them.
- Two seconds with eyes off the road doubles crash risk (NHTSA / Virginia Tech). A shoulder check costs more than two.
- Research conducted at Edinburgh Napier University measured 139 milliseconds faster reaction to rear hazards.
- HINDSIGHT certified lenses are passive optics. No batteries, no screens, no maintenance penalty.
Look for the HINDSIGHT certified mark on every approved partner product. The standard is the product. The lens is the proof.
