Jackson Cross Cylinder is a lens of fundamental importance inoptometry with a key role in the refraction routine. And yet it appears not tobe as well understood as perhaps it should be. The purpose of this paper is toexamine the linear optical character of the Jackson cross-cylinder and, inparticular, those properties associated with the operations performed on thelens in the refraction routine, namely flipping and turning. Corresponding tothese operations in physical space are steps in an abstract space, symmetricdioptric power space. The powers of all Jackson cross-cylinders lie in theplane of anastigmatic powers in the abstract space. In particular the powers ofan F Jackson cross-cylinder (for example, a 0.5-D Jackson cross-cylinder has F= 0.5 D) lie on a circle of radius F centered on null power. Flipping the lenstakes one diametrically across the circle; turning the lens takes one aroundthe circle at twice the rate. A subsequent paper shows how these operationswork in defining the cylinder in the refraction routine.

Precision and Durability Combined

Built from high-quality optically ground glass and robust metal components, the ConXport Jackson Cross Cylinder delivers exceptional durability and optical precision. The scratch-resistant glass ensures longevity, while the nickel-plated brass handle allows for a comfortable and reliable grip even through repeated use. Its smooth rotating mechanism facilitates swift and accurate measurements for clinicians.


Perfect for Clinical and Laboratory Use

Designed to meet the demands of eye clinics, optometry labs, and ophthalmology segments, this Jackson Cross Cylinder supports a wide array of vision testing requirements. The double-ended and axis-marked design simplifies both near and distance vision assessments, providing efficient and reproducible results for patient care.


Safe, Convenient, and Easy Maintenance

This instrument includes a protective carry case for safe transport and storage between uses. Cleaning is straightforwardsimply use non-abrasive agents to sterilize the surface without compromising the optical or mechanical integrity. The all-manual operation means there are no batteries or power sources required, allowing effortless and reliable performance in any clinical environment.
