Lensometer can be used in optical spectacles, spectacles shops and ophthalmological department of hospital to determine the optical parameters such as apex diopter, cylindrical astigmatic diopter, cylindrical astigmatic axial angle and the prismatic power. It is an essential optical measuring instrument for correcting defects of vision and inspecting the lens during production.
