The lens used in this study is a 90 diopter
ophthalmic lens that is produced for ophthalmologists.
In this study conducted in 2015, mean refractives pherical equivalent (SE) before operation was -3.401.70 diopters
Like the Bushnell Quest, the LRB 7x50SPD has a one-piece body and left-eye interpupiliary adjustment, but it does not have center focus, instead requiring individual eyecup diopter

Unlike conventional IOLs, the TECNIS Toric 1-Piece IOL can correct a patient's loss of focus due to pre-existing corneal astigmatism of one diopter
Designed to work in conjunction with the hooded front sight, the Rotary Diopter
Sight System attaches to the receiver's M1913 rail.
There are a number of other important features: a precise, lockable diopter
setting and aspherical lenses that eliminate a blurred view in the marginal ranges, and they just feel right.
A day-to-night offset of 1/2 or 3/4 diopter
* is typical, says Bowen, who prescribes night-driving glasses for some patients.
Other features include ergonomic center-focus; diopter
adjustment for precise, repeatable settings; multi-coated lenses; Aspherical Lens elements for flatter field-of-view; High Lux System (HLS) prism coating; sliding eyecups; and black rubber armor or leather coating (Leica Sport Optics, 1-800-222-0118, www.leica-camera.com).
The center-mounted diopter
adjustment locks in place.
The expanded range for the Visian ICL with CentraFLOW will now go from -0.5 diopter
to -18.0 diopters
on the myopic range and +0.5 cylinder power to +6.0 for the Toric ICL models.
