Further moon missions are being planned.Captain Gene Cernan was the last man to leave a footprint on the lunar surface.
The first lens, the cornea, has a power of 60 diopters. This is constant, it can not change. The second lens, directly behind the cornea, is the one that is responsible for adjusting focus. This lens' shape is changed by muscles in the eye. It has a zero to 4 diopter range. At zero, when the muscles are relaxed, the eye is focused on infinity. When it is "flexed" to it's maximum of four, the eye should be able to focus on something that is at least 25cm away.
