An UPDATE:
I kept using MY PRECIOUS TIME, and learning stuff from ytube and internet. I’m glad I kept coming back to Assetto Corsa game and different free Steam VR experiences/mini movies for testing. It’s not the easiest thing to deal with as bad image makes me bit uncomfortable, dizzy. But my efforts helped me to CONFIRM the issue and I believe I found a solution. It is to do with a shape of face and distance from eye to glass. When I adjust/pull headset on left eye maybe milimiter back, same time keeping right side as it is, the IMAGE GET’s CLEAR ON separately left and right. I believe I need a spacer what STUDIOFOAM Creative offers. There is a youtuber from Australia, he did 3Dprint his own wedges and put in bottom of both sides. An update regarding not sharp image in one eye. I did DIY a side spacer from velcro (similar as in Studiofoamcreative.com) and did insert it in between device frame and soft padding on bottom left side about 7cm long. That improved sharpness in left eye image. But now headset does not sit on my face symmetrical. Quite a strange feeling. If you wondered, the vision in my both eyes is symmetric and my face is fairly symmetric too LOL.
Please let me know guys what you think
