Conversentibus unius puncti radiis, ad punctum situm post oculum, im-
possibile est fieri distinctam visionem.

Mnis enim oculus Fabrieatus est, ut aue remoca distincta vi-
deac, quae radiane quali parallee, auc propinqua, quae diver-
sences mircum radios; radiis aucem conversencibus (qui ab arce,

Si centrum oculi, directe a visibili recedat, vel ad illud accedat; erit
i tangens semianguli viforii unius stationis, ad tansentem se-
mianeuli visorii alterins stationis; ita reciproce, distantia cenri
ocularis, a centro visibilis unius stationis, ad distantiam centri ocna
