How contact lenses are made (Video)
length 4:44
This video shows how a contact lens is made … from lathe, to polisher, to sterilization. The process is more involved than you might think, though disposable lenses must be more automated then what’s seen here. Interesting how topography is used to check the surface of the lens.
fantastic and informative. how to download these videos in mpeg format for powerpoint presentation.
Very useful and interesting and it would be better if we could download them for presentation purposes.
Thank you
