Mirror Lens technology - The external appearance and color of the lens does not mean that it also filters the given spectrum from sunlight. For example, if the lens is blue on the outside, it does not mean that you will see a blue image through it. The color or tint of the lens is determined by its material, not by the color finish. It has only a minimal effect on changing color vision. All mirror lenses of the QX and QP series are multi-coated and pass the most rigorous tests. The lenses provide good scratch resistance and wear life. The surface treatment is uniform and the same over the entire surface of the lens. Thanks to this, rainbow effects do not occur on the sides of the lenses.
