ABO REVIEW
refraction - when the direction of light changes as it passes from one medium to another(bending
of light)
a lens has a front surface power of +2.00D and a back surface power of -8.25. the corrective power is.. -
+2.00 ( -8.25 = -6.25D
Absorption - amount of light that stays in an optical material
accommodation - the process by which the eye's lens changes shape to focus near or far objects
on the retina
amblyophia - lazy eye
amplitude - height or depth of a wave
aqueous humor - produced by the cilliay body
fills the anterior and posterior chamber
weko edgers - set on 36.5 to cut the lenses to the exact pattern size
astigmatism - football shape eye
two different powers
average human eye size - 1 ans 1/8 inches
average PD for adults - 50mm to 75mm
crest - highest point of a wave
, cylinder lens - two true powers
one is plano and other is 90 degrees away
dioptric difference between the lenses for the prescribtion of OD +2.00D and OS +.50D would be.. -
+1.50 D
diplopia - double vision
dispersion - breaking down of white light iinto colors
Red Orange Yellow Green Blue Indigo Violet
fibrous tunic - the outermost layer of the eye, consisting of the cornea and sclera and connecting
with eye muscles
frame difference - the difference betweeen the horizontal and vertical measurement
Ex. 50-45= 5mm
fusion occurs - in the brain
geometric center - point where A&B intersect
hyperopic - Able to see objects at a distance clearly but having trouble seeing things up close;
farsighted
small(flat) eyeball
plus lens
