It's important to note that eSight won't restore vision wholesale in every case. According to CEO, Dr. Brian Mech, the technology has a 50% chance of working in all conditions. It's also, in its third iteration, still bulky, operated with a separate handset that adjusts for stuff like picture and contrast, and is not yet waterproof. Still, they're getting there, he tells CNET, and is bullish about the prospect of adapting the technology to contact lenses: "We're not talking 20 years from now, we're talking about maybe in the next five to 10 years." (If you remember your Star Trek lore, LaForge eventually got those too.)
For now though, it's enough that people like Felix can experience seeing anything, especially the moments that count, like seeing her 2-month-old son for the first time. "It was the most beautiful image, like it's burned in my mind for the rest of my life," she said.
