Ophthalmic Trial Lens Set

Ophthalmic Trial Lens Sets are a type of equipment used in ophthalmology and optometry practices. They are part of the supply class Ophthalmic Instruments, Equipment, and Supplies, which falls under the supply group Medical, Dental, and Veterinary Equipment and Supplies.

Ophthalmic Trial Lens Sets are used to determine the appropriate prescription for eyeglasses or contact lenses. They consist of a collection of lenses with different powers and shapes that can be interchanged to simulate different corrective lens options. These sets typically include spherical lenses, cylindrical lenses, and prisms.

During an eye examination, the ophthalmologist or optometrist will use the trial lens set to perform a refraction test. This involves placing different lenses in front of the patient's eyes and asking them to read letters or identify objects at a distance. By assessing the patient's visual acuity with different lens combinations, the practitioner can determine the most suitable prescription for the patient.

Ophthalmic Trial Lens Sets are an essential tool in the field of ophthalmology and optometry, allowing practitioners to accurately diagnose and correct refractive errors in patients' vision.
