The device for blank pressing glass bodies includes a first rotary indexing table with preforms for forming parisons from glass gobs; a second rotary indexing table having pressing molds and pressing tools for pressing the parisons into final form after formation in the preforms; and a device for shifting the first rotary indexing table relative to the second rotary indexing table so that each preform is positionable in a transfer position between a pressing tool and a pressing mold. Each preform is mounted on the first rotary indexing table by a indexable mount for holding it in a first horizontal position or in a second position pivoted away from the first position, so that, when a preform is in the transfer position, the indexable mount can be pivoted, so that a parison in it drops into the pressing mold for pressing by the pressing tool.

Device for blank pressing optical glass bodies

The optical lens, especially for a motor vehicle, is provided with a soft-focus effect, e.g. to soften a light-dark boundary on an illuminated surface. For this purpose the optical lens has an optically active surface (') provided with an embossed fine structure () extending radially outward in a direction from an optical axis (O) toward an outer periphery (P) in an undulating form and an embossed microstructure () superimposed on the embossed fine structure (). The fine structure () has a roughness that is greater than that of the microstructure (). The fine structure () preferably has a roughness of from 1 &#x3bc;m to 10 &#x3bc;m and the microstructure () has a roughness (h) in a range of from 0.1 &#x3bc;m to 2.5 &#x3bc;m.
