I am having a lot of trouble with my reticle disappearing. When I first look through my scope (6x24 FFP PST) the reticle is sharp and thick. The more I look through my eyes adjust and focus on what I'm looking at through the scope. When this happens my reticle completely disappears. I have to close my eyes and let them readjust constantly.

Is this a training issue or a scope set up issue. I'm having a hard time trying to get the LOP and they eye relief perfect as well. If on low power I have to move back some and on max power scoot up some. This scope doesn't seem to have a spot that likes a single spot for the entire magnification range.
