HindSight Cycling Glasses put eyes in the back of your head! 

In addition to bikers, law enforcement, teachers, and others could find these glasses very useful.

This has been a pack-in with kids magazines in the 90s😂 „Spyglasses“

Keeping my head on a swivel for 60+ Years awesome product definitely going to check these out to watch my 6👍🏼

Pretty cool. I use a Take a Look glasses mirror with great results but this is much more stylish.

That tip on turning right to see items behind your left is pretty neat. I wonder how much helmets interfere. Jake's helmet is like a chili bowl, so there is not interference. But not all helmets are like his.

Thanks for the review! Love the feedback, and the enthusiasm for our tech 😎.

This is amazing!

This might be the first commercialized/modern version, but my great grandfather had a pair of these circa 1920 because he was deaf from birth and couldn’t hear behind him… he might have made them DIY since he was an engineer 🤷🏽 circular glass with small slices of mirror on the outer edges, very similar design. These look much more comfortable and advanced than what he was rocking though 😂😎

How the hell did I miss this one? Never enough professor, more content from you. Always informative. I send every new rider to your Learning w Leary series. Glad to see FM wasn't able to poach you.

Why’d you reupload??? You gotta tell us

Pretty cool product! Wish they were polarized. Dang Jake your sub count is going crazy!

Comprehensive lucid review!

a helmet mounted mirror does a good job for about $10

Ooof! That price is harsh but I just might with that discount…

Since I wear prescription glasses, I would need wrap arounds. I can see where that would just not work, as the glasses would get in the way.

So they took my toy from 40 years ago and making a profit. Good thinking.

Do you just notice when people approach you from behind or do you have to actively look periodically to notice them? Also, do the temples obstruct the mirrored view at all?

Their website seems to be down

Where’s the link?

FUUUUUUUUUUU- I had an idea to produce glasses like these, but wanted to test different lense shapes. I also wanted to price them at around 30 dollars. Fortunately I'm not seeing the designs I'd picked out here.

Good idea. Purchased. But $33 shipping to US address ? Seems silly high !

Use them when younger when sold stuff in highschool we could win glasses like this and we use them for looking at girls asses the awsome way and tell them hate to see u leave but looks good bAcc here and they would flicc us off and when u tell them flicc me off really abd they trip and wonder how we saw that and u got them cuz the glasses lol and say ur dealing u can see if someone sneaking up it for woman at night or day for sad men thay have to do bad things to be with woman now we can catch who ever why we are doing stuff and be safe

This is a really just a re-marketed kids spy toy.

I was wearing glasses mirrors 40 years ago

That's cool, but not close to $200 cool. Many many far cheaper options
