SL-266B OPTICAL TRIAL LENS SET

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△. Additionally, it allows for the assessment of binocular vision by separating the visual fields based on color in the selected corrective glasses.
