Variable Lens System for Refractive Measurement

Variable Lens System for Refractive Measurement

A refractive measurement tool measures refractive aberrations of the human eye. The tool includes a variable lens system. One or more refractive attributes of the variable lens system-such as spherical power, cylindrical power, cylindrical axis, prism or base-are adjustable. The user holds the tool...

Zusammenfassung:A refractive measurement tool measures refractive aberrations of the human eye. The tool includes a variable lens system. One or more refractive attributes of the variable lens system-such as spherical power, cylindrical power, cylindrical axis, prism or base-are adjustable. The user holds the tool up to his or her eyes, and looks through the tool at a near or far scene. Iterative vision tests are performed, in which refractive properties of the variable lens system are changed from iteration to iteration.
