There was an item in the newspaper today - Dow Corning has been working with an NGO on ways to reduce the many problems associated with poor vision and lack of access to prescription corrective glasses. So they have been testing a prototype of a "self-adjustable" lens. A person puts on the glasses, manipulates what sounds like a form of pump to adjust the amount of an "optical silicone fluid" in the lens to adjust the power of the lens. The adjuster can then be detached and the user has what look like a normal pair of glasses.
My mind is boggled! I wonder if optical silicone fluid would be lighter than, for example, HD glass in modern camera lenses? And how about a hydraulic adjustment to zoom rather than via mechanical motors and gears? stan -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
