What effects on prism will changing a myope from contacts to glasses
have?CLS eliminate the Bin of minus specs upon convergence for
near gaze
What effects on prism will changing a hyperope from contacts to glasses have on near
gaze?Cls eliminate the Bout of plus specs upon convergence for
near gaze
,If you switch a myope to contact lenses from glasses, how will their accommodation and
convergence demands change?They will need to accommodate
and converge more
If you switch a hyperope to contact lenses from glass, how will their accommodation
and convergence demands change?Hyperopes will exert less
convergence and accommodation through contacts compared to glasses
What is the order of accommodative demand from least to most in specs and contact
lenses?Specs: Myope<Emmetrope<Hyperope
Cls: Hyperope<emmetrope<myope
What are the three layers of the tear film?1. Lipid layer
2. Aqueous layer
3. Mucin (mucous) layer
What secretes the lipid layer of the tears?Meibomian glands
Glands of Zeiss and Moll
,What is the function of the lipid layer of the tears?Retard
evaporation of the tear film between blinks and promotes tear film stability
What secretes the aqueous layer of the tears?Lacrimal gland
Glands of Wolfring and Krause
What is the function of the aqueous layer of the tears?1.
Lubrication of the corneal surface
2. High optical quality
3. Maintains neutral pH
What secretes the Mucin (mucous) layer of the tears?Goblet cells
What is very abundant in the mucin tear layer?Glycoproteins
What is the most important layer of the tear film when it comes to contact
lenses?Mucin layer
, What are the functions of the mucin layer?1. Decrease surface
tension an minimize dry spots
2. Minimize hydrophobic effects of lipid layer
3. Remove metabolic wastes with blinks
What are the tear film abnormalities discussed in class?1. Aqueous
deficiency
2. Mucin Deficiency
3. Lipid Deficiency
4. Lid Surfacing Abnormalities
5. Tear Base Abnormalities
What two syndromes are associated with aqueous deficiencies?1.
K Sicca
2. Sjogren's syndrome
What medications can decrease aqueous production?1. Anti-
anxiety
2. Anti-histamine
3. Anti-cholinergic
