Therefore, in the past two years, optical manufacturers have also developed ophthalmic lens for driving at night, they expect to use the optical characteristics of the lens to increase the safety of night driving. The purpose of this study is to use the spectrum analyzer, wavefront sensor and modulation transfer function (MTF) test system to measure the optical spectrum and characteristics of the two brands of driving lenses on the market, and then analyze and compare them. We collect the night driving lenses from two different manufacturers on the market, according to the refractive index and diopters of the lens, the lens specifications are refractive indices of 1.5, 1.6 and 1.67, with diopters for plano, -3.00 and -6.00. The samples collected from two manufacturers have a total of 18 ophthalmic lenses, and the night driving lenses are measured by our proposed method. The results show the transmittance characteristics, wavefront aberrations and MTF values to find out the discrepancy of two different manufacturers' lenses for night driving, and to explore the relation with the refractive index and diopters of the night driving lenses.
