Make sure the lenses are clean, and make sure the power selector is turned all the way down. I don't know how old your scope is, but on the current version there is an adjustable eyepiece with a lockring. However, the adjustable eyepiece is for focusing the reticle to your eyesight. If the reticle is already sharp, you should not need to touch that. But try this: look through the scope at a blank wall or ceiling across the room and close your eyes for a few seconds and then open them. Is the reticle instantly clear and sharp, or does your eye adjust to it? Do that several times until you can decide if it is instantly clear or your eye is adjusting to make it clear. It should be instantly clear and sharp, and if it's not, the eyepiece needs adjustment. I suppose if your eyepiece was adjusted way wrong for you, and your eye was struggling to focus on the reticle, the image behind the reticle (the field of view) might become blurry….
Youre right the eye piece needed adjustment, did that first put the power on low 2.5 picture crystal clear but
as i zoom the picture in the scope gets progressively blurry as you zoom, i checked my 243 with a bushnell 3x9 picture clear throughout zoom range.
Otherwise, there might be some moisture in the scope. It is a gold ring scope and has a lifetime warranty. They will fix it or replace it if there is a defect in workmanship that caused the problem.
