We can create “optical illusions” in order to enhance the cosmesis of patients and/or to hide defects that would otherwise make the patient insecure, with nothing but lenses. Here are some examples of ‘cosmetic optics’:
Changing the appearance of the size of the eye:
- Plus (+) power increases the eye size and brings the appearance forward.
- Minus (-) power makes the eye look smaller and recessed
Changing the appearance of the lids:
- Minus (-) cylinder at axis 180 gives the illusion of a narrower lid opening
- Minus (-) cylinder at axis 90 gives the illusion of a wider lid opening
Hiding a superior sulcus defect or pseudo-blepharoptosis:
- Gradient tints in lenses can mask an upper lid defect
