Objective

Students are able to explain and solve problems by drawing and calculating related to the eye, optical instruments and lenses, their problems, function and correction. Areas are (1) refraction at single spherical or plane surfaces, (2) thin lenses, (3) thick lenses, (4) sphero-cylindrical lenses, (5) thin prisms, (6) prismatic effect, and the manipulation of lens form and setting to obtain the desired control of prismatic effect, (7) mirrors.

Content

Refraction at single spherical or plane surfaces
o Curvature and sagitta
o Refractive index and rectilinear propagation
o Vergence and dioptric power
o Object-image relationships
o Lateral magnification
o Snell’s law of refraction
o Total reflection
Thin lenses
o Vergence: dioptic and effective power
o Object-image relationships
o Lateral magnification
o Lensmaker’s formula
o Ray tracing
Thick lenses
o Object-image relationships
o Cardinal points and principal planes
o Dioptric power
Eye models and sphero-cylindrical lenses
o ametropias and refraction of the principal meridians
o sphero-cylindrical lenses and the location of foci, image planes, principal meridians, least blur confusion
o dioptric distributions in lenses, also between principal meridians
Lens prismatic effect
o Prentice formula

o vertical prism effect
Mirrors
o Planar and spherical reflection
o Proportion of light reflected from a surface (Fresnel’s law)
o Object-image relationships
