The dashed lines are not rays; they … WebConvex lenses flip the image of the object so that the real image is rotated by 180 degrees (upside-down). Surely this would confuse the brain if convex-lens glasses are implemented because when the image is flipped somewhere along the optic nerve/brain after passing through both the cornea and the convex-lens glasses, the final image would be upside …
WebA convex lens is a lens that has an outward curve on one side. They are called converging lenses because they focus the light into a narrower beam. People who need to improve their close-up vision have glasses with convex lenses like the reading glasses in this telescope. DIY Telescope Supplies Needed
