I agree in general that it would be useful in these situations.

As someone who wears glasses, I find it impossible to run with them because of the movement or them just falling off. Are people who wear glasses able to run with them - am I doing something wrong?

At the gym I don't really need it on the machines. Treadmill is flat, ellpitical removes bounce. But if I'm sprinting outside they can start to slide.

Get a strap for your glasses and have it pulled fairly tight to your head. They are cheap. One similar to this. It needs to be the correct shape for your glasses frame so it's probably best to go to a real store and try a few straps in person.

A lot of runners wear sunglasses, sometimes with prescription lenses. Talk to your optometrist. Everyone has a unique head shape so you might have to try several pairs until you find one that stays in place.

I ran cross country and track and field with no trouble while wearing normal prescription glasses, as did several friends. I wear my glasses fairly snug, but unfortunately everyone's ear and face shape is odd in their own ways, so it might not be possible to get a secure fit that is also comfortable.

Worst case scenario: Companies make what are essentially prescription goggles, like you can see in the NBA

I always run and cycle with glasses, no problem at all. I even have reasonably heavy sunnies. Just make sure they are a tight fit and metal frames help form them around your head. I have never even noticed them really.

I don't like running with glasses because they end up getting covered in salt and sweat, but I don't have a problem with them staying on. I would guess that largely depends on the frames you have.

Try cyclist glasses. I run with Rudy project rydon and it stays on with no goofy strap.
