The glasses use nylon lenses.They polarize light and protect the eyes from ultraviolet radiation. Thanks to this, the image becomes darker and without glare - this will be especially important for drivers while driving or fishermen to see through the water. These glasses are even tested for UV protection - they do not show the image on the smartphone.
The frame is made of steel - it is much stronger than plastic or carbon fiber. At the same time, the glasses weigh only 18 grams and are almost unnoticeable when worn.
The bow between the eyepieces is curved, and the pads are made of soft slickon. Therefore, they do not press or rub the nose in any way.
