Detailed profile
It is the new product for examining the ocular aberration and evaluating the ocular optics by the technology of subjective beam tracing. There are many ocular aberrations caused by inheritance and growth, such as the curvature distribution abnormity on the surface of cornea and lens, uncoaxial cornea and lens, uneven refractive index distribution of ocular structures, which all affect the eyesight. Brite Eye Aberrometer measures these abarrations and describes them by wave aberration on the surface of pupil. It has similar functions with corneal map except that: Brite Eye Aberrometer provides the integrated aberration distribution of the whole eyes while the cornea map only provides the aberration distribution on the surface of front cornea. The product also provides 20 or 35 Zernike Aberrations including the abberations of classical geometry optics, such as astigmatism, ball abberation and so on. Pupil doesn’t have to be enlarged while measuring the wave abberation and Zernike Aberration.
