In hyper-metropia, the accommodative convergence, withoutcorrection of refraction, is, of course, greater as arule than in emmetropia. What conditions lessen the accommodative… … Fig. 46.—The conditions in a myope who has latent convergencein distant vision. shew how the diminution of accommodative con-vergence (id) in myopia is made up by greater reflex(and perhaps also voluntary) convergence (ao)y theamount of which is influenced by the condition ofthe tonic convergence…
