Just got my cv1. I've got one major problem. It's not clear enough for me, it feels like everything is a little blurry. I calibrated by looking at the green cross. Should I see solid lines across? I see almost dotted lines I.e. very pixilated. In the Hollodeck tiny town demo, it appears to be out of focus. I kneel in to look but it's not sharp. My eyes start to feel the strain after like 10mins. Please help.
