showblind
雪盲 
(形容因光線太亮而頓時失去視覺的狀況)

explanation : 
The sunlight which reflects off of packed snow can cause bright glares.  To be "snowblind" is to be temporarily blinded by the very bright light in these conditions. 

e.g. James forgot his sunglasses when he went hiking and had trouble seeing the wildlife because of snowblindess.
