Eye protection is super important for daily bicycle use, no matter weather or time of day. A single speck of dust falling into the eye at the wrong time can cause a serious accident.

The more you ride, the higher probability of such thing happening. Not to mention wind drying your eyes, it can be serious pretty fast.

Yeah, blinking lights make it more difficult to assess position and speed relative to cyclist, especially at night without street lights. At least get another one that shines all the time, or one that fades in and out but always shines at least a little, or a really good and big reflective one.
