Hi everyone,I want to build a kind of mask over monitors to show gauges and radio panel, for a better view I was thinking of buying small fresnel lens into the gauges holes. At the site www.3dlens.com they sold such lens and at very cheap prices. Does anyone evr try this? When using fresnel, are we seeing correctly only right in front of them or it's OK with a little angle?Any advices would be nice.Thanks

as far as I read .. fresnell only works if you have no angle (direct in front) so i wouldn't recomend doing what you plan ..
