I'm flying with the Zeiss Cinemizer OLED glasses. They're beautiful with bright hi-res 870x500 OLED screens. They have an HDMI port and a plain AV (composite) NTSC/PAL inputs - meaning you can attach almost anything.
The glasses support a variety of 3D formats and I can't wait to fly stereoscopic FPV.
Two things I'd like to see improved.
First, they offer an optional set of eye-cups/sun-shades that black out your peripheral vision. The glasses are fit to your face by inserting these tiny (very lose-able) plastic pieces between the nose pad and the glasses. However, the sun-shade interferes with these pieces forcing a choice between using the shades or having the glasses line up properly with your eyes. If you have a face that doesn't require you to use any of the inserts - you're fine.
Itty Bitty Losable Nose-pad Inserts
Second, my first impression of the glasses was tainted because they had a serious violet chromatic aberration. Very very distracting. It turned out that the severity of the violet flares was due to a misfit of glasses to my face. You need to get your pupils aligned to the optical axis of the eyepieces. Thus, the use of the nose adjustment inserts. Here's the rub: there is no inter-occular distance adjustment (imagine laying a ruler across the bridge of your nose and measuring the distance from the center of your left pupil to the center of your right). I'm 6'3" with a fat head to match - so my eyes are a little further apart than average. So I'm unable to align both eyes - leaving me to choose which eye will see a clean image and which will see violet flares.
For a set of glasses this expensive and video/optics this nice, a couple of rack and pinion adjustments for the nose pad and inter-occular distance would be nice. It would improve the experience tremendously and get rid of those silly, guaranteed to get dropped in a wheat field, tiny plastic nose pad spacers.
