But it's hard to judge a model both the form and the separation of the holes that the thickness does not have the same effect on everyone, ideally can try help a lot.
This is my 2nd pair and they suit me better. But it's personal.
I read in the comments that this kind of glasses can be used as sunglasses, watch, not at all. If it reduces the ambient light, the rays not pass the holes are neither arrested and filtered and therefore there is some danger in using them as mountain sunglasses and especially never look at the sun. These are not sunglasses.
