What effects on prism will changing a myope from contacts to glasses have? -
(answers)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? - (answers)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? - (answers)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? - (answers)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? - (answers)Specs: Myope<Emmetrope<Hyperope
Cls: Hyperope<emmetrope<myope
