My glasses are ~6 years old. I can still through them, but it could be better. They scratch way too easy.
Oops, I misread your question. I don't have cycling glasses, just regular glasses with polycarbonate lenses. They're tough, but don't cover the eyes as much as they should for cycling.
@Criggie I can understand BMX riders because their races are very short, less than a minute if I remember correctly, but a downhill racer could probably spare a second or two. He's going downhill after all and Aaron proved it that you don't need to push the pedals that hard.
There was an XC race yesterday in my city, in one of the parks and a guy abandoned after just 2 seconds after he broke his chain.
Nice course in the forest. What was so bad about those jumps, did you fall or almost felt?
So there are two ways it could go badly - there was the front fork turning on landing, because the sideways load is not held by the rider's arms, and its in front of the normal contact point so trail becomes negative and adds to (desire to turn) rather than subtracting.
The other possibility is the front brake is on and the whole bike does an endo, so you flip over and stop quickly.
The correct technique is to power into the jump, take off so the front wheel doesn't drop like that. You want the back wheel to touch down at the same time as the front, or slightly before.
After that I started trying to absorb the bumps with the legs, keeping th ebody "flying level" as much as possible. Less showy, but probably faster cos you can power down the slope on the far side.
I can confirm this after falling down at very low speeds - 0 km/h :-) Though what I meant earlier was that even if you don't fall right, there's less chance of losing control.
