Abstract

Perfeccionamientos en la fabricación de cristales para gafas de sol, caracterizados porque el cristal se constituye, por una pluralidad de hojas transparentes dispuestas verticalmente adyacentes entre si, que se extienden lateralmente , curvadas en un plano horizontal alrededor de la cara del portador de las gafas, estando una de dichas hojas libre de impedimentos para determinar una abertura visual alargada, y estando al menos otra de dichas hojas provista de celosías que se extienden longitudinalmente , estando dispuestas estas celosías a determinada separación entre si para determinar una hoja de protección parcialmente transparente y verticalmente adyacente a dicha hoja provista de la abertura visual.
