Rather than get sick or headaches; why not just buy Denkmeier's LOA 21mm 3D eyepiece pair (and possibly an extra non 3D epepiece for when you want to binoview withot 3D). LOA 21 3D is both proven and fun!
I didn't like the LOA 3D eyepieces.
I read a lot of amazing reviews about them and dreamed of buying them for several years. And when my dream came true, it became one of the biggest disappointments. I tried to force myself to love them, used them both in my 10" telescope and in 18" with different settings and as recommended under a very dark sky, but I could not see the smoothness of the transition in the three-dimensional image. Yes, the 3D effect is certainly present, but it highlights the square of the plane, which by itself no longer has an volumetric image. The visible field of the eyepiece is simply divided by squares that are closer and which are further away. I can see the boundaries of these squares very well both by double stars on the border of arrays and by a clear line in the difference between distant and approximate stars.
Globular clusters were not voluminous. I didn't see the shape of a ball in them, there was only a square of the plane in the center of the globular cluster, which was either closer or further away depending on the setting. But there was no shape of the ball. There was also a 3D effect on planetary and small ones, but again, the nebula stood out closer or further against the background, but there was no volume. I also looked at the large Orion nebula, which filled the entire visible field, and also noticed that it was simply divided into squares, some of which were closer and others farther away, but these were exactly flat, square parts, and not smooth transitions of depth.
As a result, I sold these eyepieces.
I liked the view much more through a couple of ordinary 32mm Plössl eyepiece on scattered clusters and nebulae, and with them I just noticed a small volume and that the stars are really some closer and others farther away. This was most noticeable in the double cluster.
