Adjustable Ophthalmic Trial Frame – Eye Refraction Testing Frame

The Adjustable Ophthalmic Trial Frame is a precision optical instrument designed to hold trial lenses during subjective refraction testing and spectacle prescription assessment. It allows ophthalmologists and optometrists to evaluate refractive errors, including myopia, hyperopia and astigmatism. Featuring adjustable pupillary distance, rotating lens holders, nose pads and temple arms, the frame provides accurate lens positioning and comfortable fitting during examinations. Suitable for eye hospitals, optometry clinics, ophthalmology centres, optical shops and vision screening facilities.
