G-Scope has no light-focussing lenses. Instead, it has an aperture to project an image on the retina. The laser-cut hole size of our G-Scope is truly microscopic. The photon energy passing through this hole is miniscule, and dispersed over a large retina area. The resultant visual brightness when looking directly at the sun is less than a 5 watt lamp observed from one metre. It is entirely safe to look directly at the sun using G-Scope.
