The Trial Lens Set Reduced Aperture 232 lenses is a comprehensive kit designed for precise vision testing and refraction. This set includes 232 lenses with reduced apertures, typically around 25-26mm in diameter
Lens Types and Powers: The set features a wide range of spherical and cylindrical lenses, both concave (-) and convex (+), to examine various refractive errors such as myopia, hyperopia, presbyopia, and astigmatism
Spherical lenses range from ±0.12D to ±20.00D, while cylindrical lenses range from ±0.12D to ±6.00D
Design and Construction: Each lens is secured in a plastic or aluminium ring, ensuring durability and ease of handling. The lenses are marked with power indicators on the handles for quick identification during examinations
Applications: This trial lens set is ideal for use in clinical settings, particularly for patients with high refractive errors or those requiring eccentric viewing. The reduced aperture lenses enhance prescription accuracy by providing a more precise vertex distance measurement
