Ciliary muscles and suspensory ligaments (and Lens)
Ciliary muscles – focusing muscles that change the shape of the lens.
Suspensory ligaments – focus pullers (the ropes): connectors that join ciliary muscle to the lens.
The silly muscle man (ciliary muscles) was wearing suspenders (suspensory ligaments) and admiring himself so much he hadn’t noticed he’d stood on his glasses’ lenses (lens) and broken them.
Ciliary muscles and suspensory ligaments work together to change the shape of the lens, and thus enable objects near, far and in between to be focused on the retina for sharp vision. This ability is known as accommodation.
The ciliary muscle acts like the sphincter of a bottom (i.e., a circular muscle that normally maintains constriction of a natural body passage or orifice).
