Ophthalmic Trial Lens

Ophthalmic Trial Lenses are a type of lens used in optometry and ophthalmology to determine the refractive error of a patient's eyes. 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 Lenses are typically made of glass or plastic and come in various shapes and sizes. They have different optical powers, which can be combined and interchanged to simulate different prescriptions. These lenses are used during a refraction test to determine the appropriate corrective lenses for a patient.

During an eye examination, the optometrist or ophthalmologist will place different trial lenses in front of the patient's eyes and ask them to read letters or identify objects at a distance. By changing the lenses and observing the patient's responses, the doctor can determine the patient's refractive error and prescribe the appropriate corrective lenses, such as glasses or contact lenses.

Ophthalmic Trial Lenses are an essential tool in the field of optometry and ophthalmology, allowing eye care professionals to accurately diagnose and correct vision problems.
