Yup. Under. And that includes my sunglasses over my prescription glasses.

Imagine in cold weather and you have to wear a cap over your ears? Who wears glasses where the the arms aren't sitting on your ears?

You can never 'prove' anything scientifically, it's not possible. Like Newton's first law doesn't 'prove' anything about gravity, it only describes and predicts the motion of objects.

"Cyclist head and facial injury risk in relation to helmet fit: a case-control study."
https://citeseerx.ist.psu.edu/viewdoc...=rep1&type=pdf

While this doesn't prove anything, you can see from this qualitative study that anything that deviates from an almost 'ideal' fit the probability of getting an injury was much higher. .

Now in this study it doesn't distinguish if the helmet tipped back or moved to the side because it was too big or if the straps weren't adjusted properly, but you can infer that anything that could lead to these conditions (fit, straps, etc.) can lead to a reduction of the helmet's effectiveness in a crash. But my thinking is if the straps not as tight as they could otherwise be to accommodate glasses underneath or they stretch out then you may be at greater risk of the helmet tipping back than you would be otherwise opening yourself up to injury. But we can't really prove that can we?

My Specialized helmet only says not to wear anything under the helmet and not to attach anything to it like camera or mirrors, but nothing about something under the straps specifically. I guess we'll have to wait for someone to sue for that specific warning to get added by the lawyers! I might be paranoid about safely equipment, but I always ask myself, "Am I paranoid enough?"

I wear two pairs like Robert Stack did in Airplane!

I'm not very smart.
When I wear straps under the sunglasses, without thinking, I sometimes whip my helmet off first. Which sends the sunglasses flying. Can't happen with straps over the sunglasses.

I wear my glasses under the straps. I've pulled my glasses off my head when removing the helmet when I wore the glasses outside the straps. I've never accidentally yanked the helmet off my head by wearing my glasses the "wrong" way.

I call them potential organ donors.

Over the straps.

Rule #37: // The arms of the eyewear shall always be placed over the helmet straps.No exceptions. This is for various reasons that may or may not matter; it’s just the way it is.

one can avoid the issue w/ a helmet that has an eye shield

Same thing has happened to me 3 times and since I had my glasses under the straps I was able to remove my helmet without stopping. One time it was while I was riding in a duathlon and so it slowed me down but at least I didn't have to come to a complete stop.

It depends on the width of the lenses. It’s not about style but function, unless you are about style over function, then you might need more help than you can find here. . I seriously doubt that any thinking person would give it a second thought how you wear them.

I know this is heresy to some, but my glasses are more important than my helmet. They go directly on my head so they stay on, even if my helmet gets jarred.

I need glasses to see. Being a fashion statement, reducing sun glare and keeping bugs out of my eyes are nice extras.

It depends on the helmet and the sunglasses shape. On my current helmet with the glasses I usually wear while riding, going under smashes the arms of the glasses painfully against my temple and/or pulls the nosepiece too hard into my face, so I go over (when I think about it - or ride outside at all, mainly Zwift these days and not at all after being hit by a car a month ago as my bike and back are not functional). Other helmets that aren't as tight against the temple or glasses that don't go as far out before coming back in, and I might go under.

Actually, you DO want your glasses to fly off to parts unknown if you crash. Take this from someone who wore glasses on a strap, crashed, and narrowly missed losing an eye (65+ stitches - 3 layers deep - in my right eyebrow).

livedarklions

Strap over the glasses, both helmet and glasses feel quite secure because it's really being on both sides of the ears and under the jaw that secures the helmet straps. Put anything between the glasses and my head, however, and it's bound to knock the glasses loose. Me losing my glasses while riding would be a disaster--I'd basically be blind.

Sigh... I don't care what "the rules" say, since I'm the one who makes cycling rules, not the one who follows them. Also, I don't really care that much about losing my cycling glasses when taking off the helmet, since my cycling glasses are not corrective (I wear contacts). And, of course, I'm already well used to the fact that when taking off the helmet glasses should be taken off first. Yet I believe that a properly designed helmet should have its straps laying flat on the wearer's head for their entire length. The strap attachment points should be located on the inner surface of the helmet (or very close to it). What Specialized did with its Prevail II is weird. (I have no experience with the original Prevail, so I don't know whether it was also like that).

I ended up retuning this helmet. Got myself a POC Ventral Air SPIN instead. POCs are somewhat goofy and not as "serious" looking as Specialized helmets. POC's design definitely borrows something from mushrooms from Mario universe. But deep in my soul I have always wanted a POC. So, this was my chance. That POC does not suffer from this issue.

falling or failing 7 times sounds painful

Why would wearing glasses over straps keep the arms from resting on your ears?

grizzly59

Be careful with this, as this will cause you to dog-track crookedly down the road.

canklecat

You'll like the POC in summer heat. The ventilation is excellent. I have an Omne Air Spin. I originally intended it only for riding my hybrid, but wound up wearing it often on the road bikes in summer daytime rides for the better ventilation. Only problem with the Omne Air Spin is the brow is a bit low so when I'm in the drops I have to crane my neck up a bit for an unobstructed view. So I don't wear it for harder workout rides when I expect to be in the drops, or with aero bars. I have other helmets for that.

I wear my sunglasses under the straps. A habit from wearing a "beanie helmet" when riding my Harley.
My full-face helmet has a built in visor.....but I digress.

If you are getting money from your sponsor, don’t hide the logo, It started with golf you get a close up side shot while putting, that why the logos moved to the sleeve.

I go over the straps for safety, not for looks. If you crash, you want your glasses to go flying off you rather than to be pushed into your eye or face possibly causing loss of sight or permanent disfigurement. If your new helmet does not allow you to put the glasses over the straps, I'd suggest returning the helmet.

And then always remember rule #5

REV160

Rule # 5 would say to pick up your eyeball from the road along with those bloody hunks of skin from your face, straighten out your handlebars, and finish the ride; but it would not say to intentionally do something foolish that requires invoking Rule #5.
