Too expensive for the features offered
I will give my opinion on these gunnars after several weeks of use.
First of all, the blue light filtering part is impeccable and I use them quite often, especially in the evening and at night.
Now let's move on to the negative points:
The temples look cheap and very fragile, you have to be careful when handling the glasses, as if they were porcelain. There is no anti-reflective coating on the lenses, so daytime use is complicated and quite disappointing.
The lenses scratch VERY easily. For a pair at this price, one would expect anti-scratch lenses with an anti-reflective filter...
It's a shame about Gunnar. The glasses do their job at night, but for that price, you might as well keep your money and get a 30€ pair that won't have any difference with these Gunnar.
I would add that the zoom effect is marketing bullshit.
