If you stop using glasses, your eye's axial length adjusts, but the visual system doesn't care. It'll still think your vision is distorted in the same way as before and has a dependency on the lenses you used, while accommodating as needed to make it focused. | If you stop using glasses, your eye's axial length adjusts, but the visual system doesn't care.

Whenever a cylinder is changed, the eye compensates for it, affecting all later focal planes. Equalizing seems to just "repair" one eye while leaving the other one alone. Simple binocular spherical changes (and object distance) just "navigate" the focal planes.

Simple binocular spherical changes (and object distance) just "navigate" the focal planes. When undoing the changes, you can slowly undo the cylinder change point, which creates unresolved cylinder distortion in the nearer focal planes. | ||
It's interesting how our visual system can compensate for cylinder and spherical distortion. | It's interesting how our visual system can compensate for cylinder and spherical distortion. |
