There's diopter adjustment for those with vision deficits and binocular-style focusing.
2
There's also a built-in diopter beneath the rear edge, which means it won't get spun around in your bag.
3
Zou, for example, is near-sighted, so Iris would recognize her and immediately set the diopter so she can see clearly.
4
Depending on the diopter of a lens, eyes have to rotate through fewer or more degrees to correct for refractive change.
5
The difference between PMMA and cornea ablation rates should be considered when using PMMA to test ablated diopter and smoothness for photorefractive surgery.
6
Myopia -0.5 diopter or less in either eye or hyperopia 2 diopters or greater was observed in less than 3% of children.
7
The average age of the patients was 50 years and average refractive error was -4.25 diopters (D).
8
Results: Overall, the patients showed an increase of 9.14 prism diopters (PD) during a mean preoperative follow-up of 4.2 months.
9
Attempted corrections ranged from 2.25 to 14.5 diopters of myopia, giving theoretical ablation depths of 182 to 332 microm below the corneal surface.
10
Methods: Color stereo optic disc photographs of 562 patients with POAG and a myopic refractive error of less than -8 diopters were morphometrically examined.
11
Conclusions: Corneal endothelial cell density and morphology were unchanged 2 and 12 weeks after LASIK for the correction of up to 14.5 diopters of myopia.

A, 46-year-old Indian male, known hypertensive presented with left esotropia of 25 prism diopters (PD) after head injury in a roadside accident 9 months back.
