The Metal Cross Cyl +/- 0.50 is a specialized tool used in optometry to refine the measurement of astigmatism and ensure accurate prescriptions. This tool, often referred to as the Jackson Cross Cylinder, is designed with a polished silver metal finish and comes in various diopter strengths, including +/- 0.50
The primary function of the Metal Cross Cylinder is to help optometrists and ophthalmologists determine the precise axis and power of astigmatism. During an eye examination, the practitioner uses the cross cylinder to compare the clarity of vision at different angles. By rotating the cylinder and observing the patient’s responses, the optometrist can pinpoint the exact correction needed
The Metal Cross Cylinder is constructed with a sturdy metal framework, ensuring durability and longevity. The power marks are printed on the lens surface, making it easy for the practitioner to identify the diopter strength during use
Additionally, the Metal Cross Cylinder is often housed in a protective case, which ensures the lenses remain in pristine condition and are easy to transport
