Sergio Maggi, with a MSEE in Electronic Engineering from The University of Rome, joined Texas Instruments in 1973, where he designed the first 16-bit Microcomputer in a single silicon chip (TMS 9940) and received a patent for the world first Graphic Processor (TMS 34010. US Patent 5522082).

In 1987 he moved to Silicon Valley, where he worked at Fairchild, Micro Power System and finally Logitech, where he worked from 1991 to 2009, when Glaucoma and low vision terminated his career. He was pronounced Legally Blind in the same year.

At Logitech he worked on the worlds first Digital Camera under $1000 (Fotoman 1991), the first USB scanner (US  Patent 5956158) and many of the low cost Logitech Webcams that made video communications affordable and new social interactions possible. Sergio specialized in hardware and software Image Processing, and especially in auto-exposure algorithms for still and video cameras. He also wrote the first semi-automated test software for video cameras (IQVCC 1.0).

By the year 2009 his vision was greatly reduced by Narrow Angle Glaucoma and his activity was reduced to research in video effects. Then his retirement and the “Legally Blind” status.

Having vision problems when gardening on sunny days, he made himself the first multi-filter prototype glasses. He tested some friends and found that most of them, with normal eyesight, claimed improved vision as well.

It was the start of a new project: Briter Vision^TM and the Multi-Filters Vision^TM eyewear,
