Vision Problem - Dizziness when looking through sights

[guest6l]

Gray Jay, had the same problem. I cured by raising my position thus, head is automatically more upright. You are probably looking under the brow and don't know it. This will make you dizzy.

I am asking in relation to both - dizziness, focal problems and eyestrain occur both outside and in, although mostly outside.

that rules out problems with range lighting

did you try adjusting your rear aperture? you can change its focus to be more clear like on a spotting scope
