With a bit of clever thinking and dexterity I managed to replace the glasses and the glasses intense, depending on the test with different tinted glasses, brightness. It is very easy to be deformed, but does not make a cheap impression. The frame is swung pleasant and adapts - of course depending on head shape - good, clean and closes fully seated.
The glasses are polarized. It can be seen no reflections, the color contrast but not distorted. I wear glasses while driving and water, this can highly recommend the glasses in any case.
