Q

Emmetropization

A

the proess by which the refractive state of the eye neutralises.
At birth the natural refrative state of the eye sit at around 2.00 DS +/- 2.00 DS, as the child grows the eye also grows and the refractive state of the eye neutralises

this is both an active and a passive process

Q

Passive

A

this refers to normal eye growth, therefore as the eye physcially grows in size the power of the optical components decreases proportionally reducing the refractive error and therefore maintaining emmetropisation

A

emmetropizatin describes a visual feedback mechanism in the control of eye gowth (visual experience)
