Necktec

These are double frame eyewear glasses with lifting lenses. Lenses can be removed from the field of view when not in use. Dual frame allows combining two pairs of lenses. The Uplifting glasses are necessary primarily for the farsighted. They are are suitable for myopes with progressive presbyopia and as sunglasses. Sunnies are not worn all the time, they are removed when light and shadow change quickly. Uplifting sunglasses suit everyone and especially for correcting presbyopia. NeckTec has patented Four-bar linkage for a lens lifting mechanism. Thanks to the precise calculation of the length of the levers, their attachment points and the angle of their rotation, it was possible to achieve what the designers of glasses have never been able to. The lenses in the raised position completely free the field of vision, but do not rest against the forehead, since the lenses are parallel to it, respectively, do not get dirty on the skin. This type of lifting mechanism will come in handy for smart glasses designers as it allows the near-eye-displays to be lifted when not in use, without removing all glasses.
