Working in the presence of dust.

I used 355 until recently, but I bought 655 this time considering usage time etc. I like the place where the glasses do not become cloudy and the place with good adhesion.

Previously I was using a light blue color, but because it is quite prominent, I chose this color this time. Eyeglasses do not cloud, adhesion is good, I think that comfort is very good. However, I am concerned about the printing of the lower letters. It would be nice if you let me make it more whitish and inconspicuous, or print it inside.

Soft comfortable to wear. Although the price is high, it is unexpected advantage when considering use time 25 hours.
