What is the purpose of a trial frame in optometry?

The purpose of a trial frame in optometry is primarily to allow for testing different lens powers for optimal vision. This device is utilized during the examination process to accurately assess a patient's visual needs. By placing various lenses in the trial frame, an optometrist can evaluate how different prescriptions affect the patient's vision, helping to determine the most suitable lens power.

Trial frames are adjustable and can accommodate a variety of lens types, allowing for versatile tests under real-world conditions. This process aids in finding the perfect balance for clarity and comfort, making it an essential tool in providing personalized eyecare solutions.
