I asked which model Element scope because the "immersive" ones, 10x40 and 12x50 prism types, have extremely short eye relief, like eyelash distance, a centimeter or so; they claim 18mm but I have one and think that number is optimistic/optomestric.
It could be difficult to see the reticle with glasses on unless the glasses are pressed up against the ocular, and the eye pressed as close to the glasses as possible. I have trouble seeing all the reticle: if my eye is in the perfect spot for the center cross, I can't see the edge of the reticle if I just move my eyeball, as that is enough to move my iris outside the tiny eyebox. I have to move my eyeball AND my head a little to re-center my iris. Took a while to learn to do this, and longer to figure out why.
