This was exactly my question after reading about Zeal Optics

They call the product “Transcend”. There is a small computer which assembles information from a number of on board sensors to provide location, speed, altitude and temperature information to the wearer via a micro-LCD display inside the goggles
! The image from the display is then virtually projected so that it appears out in front of the user! Exciting isn’t it?!

Transcends eye wear also provides the wearer with live performance information and details of their surrounding environment! A head mounted micro-LCD display inside the ski goggles shows real-time speed, altitude, vertical odometer, distance, location and temperature- as well as keeping track of the time and having a stopwatch and chronometer mode.
There will be two Recon/Zeal Optics Transcend lens options available. The retail price runs from USD 399.- 499. I'd say reasonable! And it's rumoured there's also an API app in development and download community in the pipeline! Details will appear on their website.
Seriously, this would be incredible technology to build into a motorcycle helmet visor! Recon/ Zeal
