Snow blindness occurs when sunlight reflects off a surface like snow, water or sand. This is a genuine concern for mountaineers challenging the Himalayas. Doubly so for anyone attempting Annapurna, the worlds deadliest mountains. It takes great skill and intuition to make the steep climb. I wasn't ready. I fell, but I didn't die. Lost on a mountain, blizzard raging, I was rescued. By a Pokémon.
