406. Is the eye similar to a camera?
Yes, your eye is exactly like a camera, except that the real image forms on your light sensitive retina rather than on a sheet of film. The lens bends light to a focus on the retina. If you are nearsighted and can only see nearby objects clearly, then your lens is too strong and bends light too much. Light from a distant object focuses before reaching your retina. If you are farsighted and can only see distant objects clearly, then your lens is too weak and bends light too little. Light from a nearby object doesn't reach a focus by the time it strikes your retina. It would focus beyond your retina, if it could continue on through space.
