Finally got my Sentinel in the mail after an extended wait. Took them out, came with LIFs for my wait(score!), put them on my helmet and closed all the blinds in my bedroom...I work nights and have blackout curtains so room is totally dark. Use the IP adjustment and get both tubes where I think they should be. Focus right tube. Front, back, front. Check. Focus left tube. Front, back, front. Check. Open both eyes...everything's just so slightly blurry. I can still read stuff but it's not as sharp as just using one eye. I double checked to make sure the lenses were clean. They were. I busted out the 14 to make sure my eyes weren't messing with me. Nope. Is it something my brain has to adjust to since I've been using a single 14 so long? Is my IP adjustment wrong and I just don't know how I really need to adjust it? The right tube is just ever so slightly less sharp than the left FWIW.
