This optical trial lens set is designed for the subjective test method of selecting corrective glasses. It enables ophthalmologists or optometrists to accurately determine the necessary correction of ametropia up to ± 20 diopters using stigmatic trial lenses. It can also correct astigmatism up to 6.0 diopters and strabismus using prismatic lenses with a prismatic action ranging from 0.5 to 10.0△.

The ophthalmic trial lens set is an essential tool for optometrists and opticians when prescribing corrective lenses for patients. This set consists of 266 lenses that are housed in a sleek, silver metal rimmed case. The lenses are made of high-quality glass, which offers excellent light transmission.
