Fixed my night vision issues! For the last 4 months or so I couldn’t figure out why my night vision was so dark. Turns out it started to focus on the brick that is near the eye on the left side & rendered everything else dark. I don’t know if there was an update or something else, but it had worked fine for over a year prior to this. Decided after reading another review about their eye focusing on their brick to try the wedge. It finally works again!!
