1. In a well lit area, put the glasses on while holding your head still. Brush any hair out of the way, and test the mirror space by moving only your eyes.

2. Don’t stare. The glasses are designed for a glance, so don’t keep your eyes for more than a second or two pointed at the mirror until you are used to them.

3. Once you’re accustomed to where the mirrors sit, turn your head 10 degrees and look the same way, and voila, you can see behind you!

You can use the HindSight box or leaflet as a training tool - put it on a shelf 3m/10ft behind you, and look for our slogan - Don't Look Back!

Be sure to use your glasses for at least 15 minutes to get use to them before testing them on any bike or scooters. 

1. While holding the frame, apply pressure to the lens until it pops out 

2. Store removed lenses in sunglasses pouch 

3. Push new lenses into frame, while aligning the raised bumps on the lens with the grooves in the frame

4. Ensure mirror bend lines are parallel - use a finger and thumb to rotate the lenses if necessary 

5. Gently wiggle the frames at the nose bridge to ensure the lens bumps are in the correct grooves

6. Test: if the mirror appears blurred, the bumps are not in the groove, adjust as necessary.
