Accommodation is an important function of the human eye, which can change the parameters of
ocular refractive system and also has a strong correlation with the development of myopia and presbyopia. Several subjective measurements have been applied in accommodation assessment such as push-up test, push-down test and minus-lens procedures. It can be measured objectively by measuring the change in refraction
of the eye with dynamic retinoscopy or autorefractor. This article reviews the application of measurement
of accommodative amplitude and research progress in accommodation, providing clinical information
for further studies．
