Your post seems like it was aimed towards a specific person, although I'm not sure who. I also agree that the eSight device is quite useful for people who can use it, although it doesn't benefit everyone.

I think some people have an issue with their advertising slogan, which is "Making Blindness History". I've had a number of clients complain that their advertising campaign makes it sound like it cures blindness and vision loss of all types, which it doesn't.

One thing I am curious about it, who told you that you don't need to use a cane when using the eSight device? When I was trained as a eSight pre-screener (this was ages ago, when the device was first coming out), we were told specifically to remind clients they still needed to use their canes. Because of the design of the device, it allowed someone to read upcoming signs and identify landmarks. But due to the reduced fields when using it, someone can't see drop offs. That is why the device can be lifted up, so the user can use their existing vision when traveling. I haven't had a chance to try the newer version of the device, but I can't imagine the fields have increased to such a significant degree. Their own FAQ says...

"With eSight’s patented Bioptic Tilt capability, users can be mobile while using the device. They can tilt the eyewear to the precise position that, for them, presents the best view of the video feed, while maximizing their natural peripheral vision (which is often still functional for people with low vision). This, along with imperceptible short latency, ensures that a user’s balance is not disturbed and, hence, no nausea occurs – common problems with immersive technologies such as virtual reality headsets."

It would normally be the peripheral vision that would detect the drop off. But if they need to use a white cane because the peripheral vision isn't sufficient, then the device wouldn't be able to assist.
