Hey there. I'm the owner and former user of a NuEyes headset and I've also tried eSight. Both of them have their annoyances. eSight has a non-detachable remote that resembles something attached to a hospital bed but it has an HDMI input and a battery that will last a few hours. NuEyes is a lot more portable and comes with a nifty little bluetooth remote that you slip onto your thumb. Unfortunately headset battery life is about an hour at high brightness and maybe 2 if you keep it lower. eSight has larger, more color-accurate displays while NuEyes' are smaller, a bit greenish, and are in the topleft corner. This may be helpful if your peripheral vision is bettter than your foveal vision. The cameras on both are mediocre at best and suffer from the typical lag so you won't be doing anything that requires a quick response time on either of these. eSight claims they have a low-latency system but it was about the same as any other camera when I tried it.

Both get pretty hot during use and the weight will get uncomfortable. Since eSight offloads the battery and processing to the attached remote it's a little better than NuEyes but that non-detachable remote is a really hard sell. I found it not too difficult to just carry a small bag with me and hook up a battery bank to my NuEyes. It was kind of buggy though and eSight had a lot more features that made it feel a lot closer to "wearable CCTV" than NuEyes.

For me, the compactness and portability of NuEyes trumped the more robust feature set of eSight... also NuEyes was an authorized DOR vendor here in the states. Like hell I'm paying 6 grand for a camera I strap to my face. Oh yeah, the trackpad on the NuEyes broke twice on mine. I think it was sweat leaking in and messing it up. Very annoying.

Do keep in mind that I no longer use these since my vision's gotten too bad. They may have improved since then. I haven't touched my NuEyes in about 2 years. I should probably return them to the DOR before they fall off my table lol

I haven't tried the NuEyes yet, but I have tried out the eSight device. It is a lot like a CCTV, but one that you wear. Definitely worth trying out if CCTVs help.
