Replace a missing or broken plus-cylinder trial lens with an individual Good-Lite glass replacement lens for refraction testing. Each lens features a chrome tabbed ring and full-aperture design. Select the required positive cylinder power from 26 options ranging from +0.12 to +6.00 diopters (D). Available powers are +0.12 D, +0.25 D, +0.37 D, and +0.50 D, followed by 0.25 D increments through +6.00 D. Sold individually: one plus-cylinder lens in the selected power, not a complete trial lens set. This listing is for plus-cylinder lenses only. Before ordering, confirm the lens-ring diameter and compatibility with your trial frame or existing trial lens set.
