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

The reduced aperture design helps in minimizing peripheral aberrations, providing more accurate results during eye examinations.

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

Additionally, the set includes accessory lenses like prisms, frosted lenses, slit lenses, and colour lenses for specialized testing

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

The set is typically housed in a sturdy case, often with removable trays and combination locks for security

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
