The Metal Cross Cyl +/- 0.25 is constructed from high-quality materials such as glass and stainless steel, which ensure durability and precision. The robust construction allows the tool to withstand regular use in clinical settings, maintaining its accuracy over time. The lenses are typically mounted in a handle, making it easy for the practitioner to rotate them in front of the patient’s eye during the examination.
The primary function of the Metal Cross Cylinder is to help determine the axis and power of the cylindrical correction needed for a patient’s prescription. By rotating the lenses in front of the patient’s eye, the practitioner can compare the clarity of vision with different lens orientations. This process helps pinpoint the exact correction needed for optimal visual acuity.
The Metal Cross Cyl +/- 0.25 diopter lenses are particularly valuable because they offer fine increments for adjustment. These subtle changes are essential for achieving the most accurate prescription possible. The ability to make these precise adjustments is crucial for providing patients with the best possible vision correction.
The Metal Cross Cylinder is typically housed in a durable case to protect the lenses and keep them clean and undamaged. This ensures that the tool remains in optimal condition for use in eye examinations. The case also makes it convenient for practitioners to transport and store the tool when not in use.
During an eye examination, the practitioner places the lenses in front of the patient’s eye and asks them to compare the clarity of their vision with different lens orientations. This process helps refine the prescription and ensure that the patient receives the most accurate correction for their astigmatism.
