Trial frame lens set TL-232

The Luxvision TL-232 Trial Lenses Set features 232 reduced-aperture glass lens pieces with plus and minus cylinders secured in plastic rings. This trial lens kit comes in a leather case with removable tray, diopter indicators, and dual combination locks for security. Wide ranging sphere and cylinder powers as well as a variety of accessory lenses will allow you to perform better vision testing. This classic form of refraction enhances prescription accuracy for low vision patients in particular, offering accurate vertex distance, which is very helpful for high refractive error patients. Similarly, any patient who relies on eccentric viewing and needs to move their eyes or head to see around a scotoma can greatly benefit from trial frame refracting. Spheres The kit includes both concave (-) and convex (+) spherical lenses to examine myopia, hyperopia and presbyopia. Powers include ± 0.12D to ± 20.00D. Cylinders Examine astigmatism with the plus and minus cylindrical lenses included in the TL-232. Powers range from ± 0.12D to ± 6.00D. Prisms You can perform prism testing up to 10∆D with the TL-232 Trial Lens Kit. Frosted Lens Use this semi-transparent cover lens for babies or outside of the room as an occluder. Slit Lens Examine astigmatism by turning this lens in front of the eye. Color Lenses The TL-232 includes red, green, blue, yellow and dark brown lenses for use in examining color sensitivity. The lenses are especially helpful for use with cataract patients as well as in color blindness testing. Additional Lenses Maddox, plano, occluder and pin hole lenses are also included in the TL-232.
