Contact Lens 被水衝走

I always wear contact lens to swim and 每次都 ok. But who knows! Bad luck strikes. I think I swim too fast and the right side of my contact lens is being washed out from my eyes!! I end up having half clear and half blur vision to drive home! Any way, the good news is I found out my this pair of contact lens already 4 years old, so I guess 舊的不去﹐新的不來。呵呵﹗
