ABSTRACT
Teaching at a college of pharmacy, I learned early on that it was important to point out the relevance of physics to students. I spent time looking for applications specifically in a pharmacy setting, as well as applications to
other courses in the curriculum, including anatomy and physiology. Now in my 18th year of teaching an IPLS course at STLCOP, the College is looking to expand our physics offerings as we begin two new B.S. degree programs
this fall. We are also planning a new physics laboratory, with new experiments and equipment. As a new department chair, I am looking for two new physics faculty to develop these courses, labs, and experiments, as well as
to develop more advanced elective courses appropriate for life sciences students..

.
Hyperopia (farsightedness) or presbyopia
near point is farther from eye for comfortable
reading
person needs to see close objects clearly
Example
near point at 40.0 cm, object at 20.0 cm
P = +2.50 D

PHYSICS AND PHYSIOLOGY
The Eye

Acts like a converging lens to produce a real image
Most refraction occurs at the cornea
Lens small amount of refraction needed for
proper focus accommodation
To see distant objects
ciliary muscle is relaxed, largest diameter
ligaments pull outward on lens flatter shape
To see close objects
ciliary muscle is tense, smaller diameter
ligaments lose tension on lens fatter shape
As a person ages
lens becomes denser and less flexible
does not relax to its fatter shape
difficulty seeing close objects (presbyopia)

The Middle Ear

Eardrum, ossicles, and Eustachian tube
Ossicles malleus (hammer) is connected to the
eardrum; incus (anvil); stapes (stirrup) connected
to oval window
Create much larger force on oval window needed
for wave motion in fluid of inner ear
This increased force is a result of two factors.
surface area of eardrum compared to stapes
lever system mechanical advantage
