OK, but you still have to look up

I ordered these after having a transformative experience using my friend's Belaggles, but balking at the price of the Belaggles ($90). These definitely help. But the prisms are small, and framed all around. So the range of vision is pretty small, which means that after your climber moves beyond 35 ft or so, you have to start tilting your head back, even with the glasses. This was not the case with the Belaggles, which had a much wider angle of view. I have now used this pair for maybe a total of 10 hours of actual belaying, and my neck still gets belayer's neck, though much more slowly than without the glasses. I'm writing this review because I've decided to upgrade to a better pair.
