Size lens set

 

Color Vision Recorder software

Product description

Optical Diagnostics sells a set of size lenses for aniseikonia management with the following specifications:

  • Set of 7 lenses
  • Optical magnification 1-7%
  • Fitted into standard trial lens rings

 

Why use size lenses?
Size lenses are lenses without refractive power, but with an optical magnification.  They are often used to evaluate the effect of an aniseikonic correction on a patient's binocular vision comfort.  A size lens check is therefore recommended before designing and ordering iseikonic lenses for a patient.  Especially with retinally-induced aniseikonia, where the aniseikonia is not constant over the retina, size lenses are extremely useful to evaluate if and what aniseikonia correction helps the patient's binocular vision comfort.

 

Size lenses could also be used to induce aniseikonia.  This allows a 'normal' to experience the binocular discomfort of an aniseikonia patient.
