I'm confused wasn't the FOV 180, but he couldnt use it cause he couldnt put it in his eye, so he was looking from a few inches away so it was ~20deg fov cause.... it wasnt in his eye lol
>the lens has a 30° FOV, but I can tell you that the perceived one was less. One of the reasons is that these lenses are made to show full FOV when they are worn on the eye, but of course, I could not do this test, so my perceived FOV with the lens close to the eye was probably just in the range 10-20°.
