Abstract
A lens and a pair of glasses incorporating the lens wherein each lens has first and second lens elements, preferably formed of mineral glass, with a bigradient coating deposited on the inner surface of the first lens element by a vacuum coating process. The lens elements are laminated together with a polarization film therebetween and have an anti-reflectant coating preferably on the outer surface of the second lens element. Waterproof coatings may be formed on the anti-reflectant coated outer surface of the second lens element and the outer surface of the first lens element.
Claims30
A lens, comprising:
- a first lens element having inner and outer surfaces;
- a bigradient coating on said inner surface of said first lens element;
- a second lens element having inner and outer surfaces;
- and
- a polarization film disposed between said inner surface of said second lens element and said bigradient-coated inner surface of said first lens element such that said first and second lens elements are laminated together with said polarization film between said two lens elements.
A pair of glasses, comprising:
- an eyeglass frame;
- and
- first and second lenses disposed within said frame wherein each of said lenses are comprised of:
- a first lens element having inner and outer surfaces;
- a bigradient coating on said inner surface of said first lens element;
- a second lens element having inner and outer surfaces;
- and
- a polarization film disposed between said inner surface of said second lens element and said bigradient-coated inner surface of said first lens element such that said first and second lens elements are laminated together with said polarization film between said two glass lens elements.
A method of manufacturing a lens, comprising the steps of:
- providing a first and a second lens element wherein both said first and second lens elements have an inner and outer surface;
- coating said inner surface of said first lens element with a bigradient coating;
- disposing a polarization film between the bigradient-coated inner surface of said first lens element and said inner surface of said second lens element;
- and
- laminating said first lens element to said second lens element with the polarization film disposed therebetween.
A method of manufacturing a lens comprising the steps of:
- providing a first and a second lens element wherein both said first and second lens elements have an inner and outer surface;
- aligning the horizontal axis of said first lens element with an aligning means;
- vaporizing a bigradient coating material with a vaporizing means disposed beneath said aligning means such that said inner surface of said first lens element faces said vaporizing means;
- blocking vaporized material along said horizontal axis of said first lens element;
- partially coating the inner surface of the first lens element such that the portion of the inner surface of the first lens element which is not blocked is coated with the vaporized bigradient coating material;
- disposing a polarization film between the bigradient-coated inner surface of said first lens element and said inner surface of said second lens element;
- and
- laminating said first lens element to said second lens element with the polarization film disposed therebetween.
