Back when I was scuba diving, we'd spit in our masks before a dive to keep the masks from fogging up. Worked like a charm.

For road riding, I am having issues with sweat falling off my brow, hitting the inside of my sunnies, and then causing problems with my vision. Only way I've found to solve the problem is to stop, whip out a cleaning cloth, and give the sunnies a clean.

Just curious to know if anyone has come up with some hacks similar to the scuba mask one at keeping sweat from sticking to the inside of their glasses. Thx.

You can try waxing the insides of the lenses with carnauba. You need to use an additive wax, nothing that cleans or polishes. Beyond that, it's often more effective to redirect the sweat to begin with.

Halo works, Sweat GUTR works, Mission Enduracool skullcaps work. But all do kinda depend on how hot/humid it is, how fast you're moving, and what helmet you're wearing. It's a lot of variables.

A Halo headband is probably the cheapest/easiest, you just have to get used to the sweat running down in front of your ears on long climbs. It feels weird. Having no hair, I lean toward the Enduracool.

Here's a simple solution. Stop wearing sunglasses.
I live in sunny Australia and I don't wear sunglasses anymore although when I was younger I wouldn't go anywhere without them and I certainly used to experience what you are talking about.
It can take a little while for your eyes to adjust but once you do you won't miss the sunglasses anymore.

Ever taken a bug to the cornea at 25 mph?
Or a piece of whatever flung up by the tires?
After a few of those events, I prefer to ride with glasses.

Wear something to wick away the sweat before it drips onto your glasses, e.g. a headband or "Headsweat®."

I would NEVER ride a bicycle at any speed without eye protection. I cannot count how many bees have slammed into my sunglasses at +25mph.

I mean, beyond that they're prescription, so if I take them off I can't really see. I also have above average night vision, so the daylight is really bright.

Not wearing eye protection isn't a solution at all.

Halo headband. It has a little rubber piece on the inside that directs the sweat away from the eyes.

NoWhammies

Considering the number of times a bug has hit me in the face or on my sunglasses at speed, I'll continue to wear sunnies thanks.

Regarding re-directing the sweat before it drops on the sunglasses, I do wear a Walz cap under my helmet. It works at keep the sweat off some of the time, but depending on a) the direction of the wind or b) where I look, I find swear might drip down on to the inside of my sunglasses. Good tips/suggestions so far. Thx.

I always use a sweatband....they work great....also adds a bit more cushion between head and helmet.

No offense, people, but the people who suggest HeadSweats or something to soak up moisture under the helmet apparently don't sweat, they do good to last an hour without needing a fresh one (as has anything else I have tried). I go through about 3 changes of clothes working outside during the summer, forget about cycling or running. I am going to have to try the wax. Nothing worse than having the vision blurred by sweat on the lens.

I second the Halo headband.

Hour long group rides at good pace and never had an issue with drippage. Longer rides and particularly slower paces tend to defeat it. In those cases I find a stop every once in a while to wring it out to be helpful.

I have utilized a few different types of glasses, and I wish I could recall all their names. Some sets were better than others about not allowing the drip to come inside, by design. I will say that my personal favorite for glasses is the Oakley "blade" variant(s). I don't get drips inside, but the way air moves around them I do eventually get a buildup of droplets that I have to stop and clean out.
By and large if the going is really slow, hot, and sweating a lot I just remove my glasses and park them in my helmet vents.

The dive shops also sell some type of anti fog that you can apply to the inside of the masks. And before anyone suggests, no its not bottled spit.

I was riding at speed across a high level bridge one day and a large bug hit my sunglasses with such force that the lens cracked. I dread to think what that would have done if my eye had not been protected by those sunglasses.

I always ride with a cycling cap under my helmet. It keeps the sweat out of my eyes, sweat typically drips off the bill of the cap. Also, the cap keeps the sun off my bald scalp.

Juan Foote

TBH, if you are using glasses for ANY vehicular purpose and having lens being cracked by bugs you need to reconsider your purchasing. There are safety standards in place that even many cheap brands of glasses conform to that would not damage in that way. Far too much at stake not to pay attention to one rating.

Miele Man

This was a severe and freak impact. I've never had such an impact again in over thirty more years of bicycling.

Pretty bad advice on so multiple levels. First off, UV is very bad for your eyes. It is the leading cause of cataracts for one. Secondly, glasses while riding, either sunglasses, or clear lenses offer wind protection, and protection from foreign objects.

Even with good glasses, you can have issue, though they will be less likely. I got something in my eye on my last bike tour. I had a scratchy eye one night, and removed my contact, and cleaned them, thinking all would be well in the morning. It wasn't. Long story short, I had a scratched cornea, and once at the doctor, I could barely make out the E at the top of the eye chart with that eye. It took two weeks for the vision to clear.

I would not recommend riding without glasses. As for fog, there are glasses cleaner that has an anti-fog built in. Here is one of many: https://www.amazon.com/Eyeglass-Clea...s%2C153&sr=8-4 Here is another: https://www.amazon.com/Jaws-Quick-An...3&sr=8-16&th=1

For sweat, that is difficult. About the only thing you can do is somehow stop the sweat before it gets to the glasses. My helmet does a decent job of stopping the sweat, but some sort of sweatband may be necessary. I tried the Halo, and it works well, but the "gutter" felt a little odd against my forehead. YMMV

Don't use Rainex on glasses, another bad idea.

No product with completely stop fogging, bit they can minimize it.

We often overlook the obvious:. Adequate airflow to cool and to evaporate our sweat.

I understand some of you are fast skinnies and pedaling at 25mph. But your sunnies and helmet may be blocking your airflow where you need it.

Standard bandana both with and without a helmet.

JohnDThompson 

I beg to differ. Without the Headsweat, I'd get perspiration pouring off my forehead onto my glasses and into my eyes, carrying sunscreen with it, which was very irritating for my eyes. With the Headsweat, I don't have that problem. Yes, it gets soaked with sweat, but that sweat doesn't end up on my glasses or in my eyes, and that's an important benefit in my book.

use a BUFF head band ... with or without a helmet ... AND don't sweat small inconveniences to your comfort > remember you're biking not LIMO ing

Halo headband or skull cap. Works in the 90F.

Y’all don’t sweat. It may buy me an hour on a good day in summer, but I need to carry several.
