Ludicrous Speed Snow Goggles for kids include your choice of helmet compatible, dual adjustable, anti-slip strap color, plus two interchangeable lenses: 1) Sunlight responsive lens for low-light conditions that magically transitions from clear to grey in the sun, and 2) Polarized mirrored lens with 100% UVA/B protection for high glare conditions.
Guaranteed to make you 22% faster and 77% radder looking (not really, but maybe!). Each pair comes with a zipper carrying case and microfiber polishing sleeve. Anti-fog, anti-scratch lens coatings, hypoallergenic foam padding and 8 vents for breathable fog-free runs.
Right Eye (OD) & Left Eye (OS)
OD stands for "oculus dexter" which is Latin for "right eye". OS stands for "oculus sinister" which is Latin for "left eye."
Sphere (SPH) aka Power (PWR)
If you’re nearsighted you’ll have a minus (-) before the number, and if you’re farsighted you’ll have a plus (+) sign.
Cylinder (CYL)
This is only for people with astigmatism. A nearsighted astigmatism will have a minus (-) before the number, and a farsighted astigmatism will have a plus (+) sign.
Axis
This is only for people with astigmatism. The axis is a number between 0 and 180 and determines the orientation of the Cylinder (CYL).
We need your Pupillary Distance (PD) to ensure that your glasses are customized to fit you perfectly. PD is the distance between the centers of each eye. Once we get your PD we can finish your glasses!
Kid PD Range: 35-65 mm.
Adult PD Range: 50-80 mm.
If your PD has 2 numbers, it is typically written 22/20 on your prescription. The first number is the right eye (OD), and the second is the left eye (OS).
1) ONLINE PD TOOL: Virtually measure your PD using our online tool! Click the "Measure My PD" button and follow the on screen instructions. Then enter your PD number in the form.
2) EMAIL A PHOTO: If your little squirmy wormy can't sit still long enough for the online tool (we totally get it!), you can just take a picture at home and we'll measure the PD for you. Follow these directions here.
Sometimes it can be hard with little ones, we totally get it! Take a picture following these directions and we'll measure the PD for you:

Our youth size goggles fit ages 5-15 years old (depending on head size) and the anti-slip silicone strap is adjustable to fit over a helmet as well.
The Ludicrous Speed Snow Goggles passed the Antarctica test; and I give them an A+! These goggles were a critical piece of my gear for the Wolf's Fang Antarctica Marathon stage of the Great World Race (7 marathons on 7 continents in 1 week, November 2025). I have a really small face and struggled to find any goggles, much less goggles with polarized lenses, that would fit. Compounding the requirement for polarized lenses to prevent snow blindness, the dangerously cold and windy weather conditions (-37 F windchill, 0 F) meant I could not stop and remove my gloves (frostbite) to address gear issues, most especially goggles (risking snow blindness). I put on my Ludicrous Speed goggles before I deplaned and stepped onto the Antarctic Ice and never once needed to adjust them. They were perfect. They stayed in place over my hat and under my hood, were completely comfortable and never fogged up once, despite wearing a balaclava tucked into the bottom of the goggles frame for most of the race. I could see clearly, including peripherally and my eyes were protected from the light reflecting off the snow and ice. (It was a ~1AM race start but complete daylight.) I am forever grateful to Ro Sham Bo for designing and manufacturing these awesome small polarized goggles. Your flawless goggles helped me earn 2nd place in the Antarctica marathon and kept me safe while running in this unforgiving environment. I love the goggles so much that I've ordered two more pair for my youngest…
This is the most inspiring review we have ever received!! You are amazing!! Thank you so much for the kind words, it means so much to us!
Customer service is amazing and very responsive. The sides gap some on my daughter but does not bother my daughter. Can’t beat the quality for the price!
YES! Love this so much!! Thank you so much for supporting our little family company!
Great goggles for my 6 year old grandson! He loves them.
My kids love these for snowboarding. They used to hate it when I made them wear sunglasses on bright days and now these goggles do a great job of protecting their eyes and they react really well to changing light conditions.
The ludicrous speed ski goggles by Ro Sham Bo are incredible! My kids actually WANT to wear goggles now. The fun colors and interchangeable lenses get the kids excited, and mom is excited their eyes are protected and there are no more fights about putting goggles on! Great product, now just please make adult sizes!!!
