“能见距离”常见的英文表达是 “visibility range” 或 “range of visibility”。
visibility range：强调能见度所覆盖的距离范围，在气象、航海、航空等领域描述能见情况时常用。例如：The visibility range was reduced to less than 50 meters due to the heavy fog.（由于大雾，能见距离缩短到了不到50米。 ）
range of visibility：意思与“visibility range”相近，也是表达可视的距离范围。例如：We could hardly see anything beyond a short range of visibility in the storm.（在风暴中，我们的能见距离很短，几乎看不到更远的东西。 ）
