When focusing on closer objects, do the lens in the eye become more or less powerful?

Also, do the ciliary muscles contract or relax when focusing on a close object?

When objects are closer the ciliary muscles contract and suspensory ligaments slacken so the lens becomes fatter, thus focusing more.

Its around an hour long, so if you just pick out the stuff you like and play it at 1.5 speed, you can still get in some nice bits.

Plus, that guys smile at the end is quite nice
