Abstract

The invention relates to spectacles having a spectacle frame (11) and at least one additional frame (20) that can be placed on the front of said spectacle frame so as to be removable, both frames having lenses (12, 22) made of transparent material. The lenses (12) of the spectacle frame (11) are varifocal lenses for the purpose of correcting vision for different distance ranges in order to achievein each case maximum or clear visual acuity for at least one distance range, while the lenses (22) of the additional frame (20) are single-vision lenses or varifocal lenses. In combination with the lenses (12) of the spectacle frame (11), the lenses of the additional frame correct vision in a manner customized to the needs of the user. In a simple, cost-effective and convenient manner, a broad field of sharp vision in all distance ranges is afforded to the user, and therefore significantly improved vision comfort tailored to their requirements is provided.
