16. Presbyopia
    With age, we all lose our ability to focus on nearby objects (accommodation). In our eyes, the crystalline lens loses flexibility and our ciliary muscles weaken. This limits our minimum focusing distance. Presbyopes with 6/6 vision need reading glasses; presbyopic myopes and hyperopes need bifocals....
