* type of refractive error is the same * BUT Amount of error is considerably unequal. > 2.00 D * correction with glasses or contact lenses |
|
|
Antimetropia |
* one eye myopic and one eye hyperopic |
|
|
Amblyopia |
aka lazy eye *dimness of vision * can not correct to 20/20 vision * visual therapy incl patching etc. To strengthen the weak eye |

* involuntary, rapid movement or rotation of the eye * often associated / photophobia * pt w/ significant amount of refractive error may benefit from CL due the lens moving with the eye |
|

Aniseikonia |
* relative difference in size and/or shape of the ocular picture * correctes w/ iseikonic lens * often results from Antimetropia or severe Anisometropia |
|
|

" Tendency " * ocular muscle out of balance * breaking fusion * once line of sight is clear ... fusion will generally occur |
|

"Definte" *both eyes are not focusing on the object viewing * the brain can not overcome the turning ofbthe eye to create fusion * may result from a weak or damaged ocular muscle or the brains inability to create fusion |
