A trial lens set is an essential optometry tool consisting of various lenses (spherical, cylindrical, prisms) used to manually determine a patient's exact refractive error during subjective refraction. These lenses are inserted into a trial frame to test vision, often for myopia, hyperopia, or astigmatism. They allow for precise testing, especially for complex prescriptions or when a phoropter is unsuitable.
