"其實不論路上光源充足與否,個人建議都不要用閃燈"
一般道路上的汽機車用閃燈多是要超車的情況下,
為了通知前車讓路才會用閃燈
(或是會車時警示對向…等)
一般燈具常亮狀態下的警示作用就已經足夠了
在沒有路燈黑漆漆的情況下,就算是LED小紅燈也是路上最亮的光源
在有路燈光源充足的情況,視力正常都看得到會車,燈具常亮模式也足夠示警
閃燈的壞處:
1.會閃得對向或周遭用路人很不舒服
人的瞳孔會隨著光源放大縮小,路上有光源一直閃爍
不論是不是刺激最強的白光還是較弱的紅光
在黑夜中看久了一定都會感到難受
2.會對散光患者造成一定的影響
散光白天的時候影響視力較為不明顯
但在黑夜時看東西會較為吃力
看燈光會容易有條狀、霧光或是有光暈的情形
3.閃燈容易讓人視力失焦
尤其是較亮的白燈更嚴重!
如果視覺上看不清楚,大腦就會一直想把影像弄清楚
就容易出現頭暈、眼睛酸澀的情況
或許有人會覺得,角度調低點不要照到人就好了?
但不要忘了光線是會折射的,就算調低到肚子或是更低的高度
眼睛仍然能接受到一定程度不等的光線射入
所以建議各位車友夜騎時:
1.不要開閃燈,前後燈都用常亮模式最好
2.前燈角度最好是照射在車前5M以內的距離就好
以免會車時遠遠地就把對向給照瞎了
不但沒有達到警示作用還造成危險
(其實白光照明雖好,但黃光才是最好的選擇
光線較溫和不像白光那麼強,而且遇到霧時穿透力也比較好)
