Outline: Optics and the Eye
Light
As a wave: frequency, wavelength,
speed
As a particle: quanta/photons
Units
Radiometric, e.g. watts, watts/m2,
etc.
Photometric, e.g. lumens, candelas/m2, etc.
Optics
Reflection
Mirror/Specular
Matte
Refraction
Index of refraction
Lenses, ray diagrams, focal length
Dispersion
Prism
Blue bends the most
Later: Chromatic aberration
Diffraction
E.g., by the pupil
Eye structure
Cornea
Lens, muscles of accommodation
Aqueous & vitreous humors
Iris and pupil, muscles for dilation
Retina
Optic disk/blind spot
Vasculature and why you don't see it
Fovea
Optic nerve
Muscle pairs and possible eye movements
Accommodation
Emmetrope
Myopia
Hypermetropia
Presbyopia and accommodative range
Astigmatism, blur circles/ellipses
Correction of optical errors
Cataracts, aphakia
Pupil control
2 - 8 mm diameter, hence factor of 16
in area
Light gathering versus depth of field
Depth of field versus diffraction
Pupils are controlled jointly
Affected by light level, emotion, etc.
Eye movements
Listing's law (why have cyclotorsion)
Tremor
Nystagmus (including optokinetic)
Vestibulo-ocular reflex (VOR)
Smooth pursuit
Saccades
Disjunctive eye movements (convergence/divergence), diplopia
