A lensometer, also known as a lensmeter or lens analyzer, is an optical instrument used in optometry and ophthalmology to measure the prescription of eyeglasses or contact lenses. It is an essential tool for opticians and eye care professionals to ensure accurate prescription measurements and verify the quality of lenses.
The primary function of a lensometer is to determine the power, axis, and other specifications of lenses. It allows precise measurement of the lens power in diopters (D) and the cylindrical power in astigmatism correction.
