lensometry

Lensometry is a technique used by eye care professionals to measure the optical properties of lenses, such as eyeglasses or contact lenses. It determines the lens’s power, including how much it bends light to correct vision. This process helps ensure lenses are accurately prescribed for clear vision and allows practitioners to verify or adjust existing lenses. Using specialized instruments called lensometers or focimeters, the device analyzes the lens’s focal length and curvature to provide precise measurements, ensuring optimal vision correction for the wearer.
