The purpose of this research was to measurement real Accommodative response amount using both eyes open-view autorefractometer. Compared each Accommodative response amount to distinction of sex, age, kind of ametropia, amount of astigmatism and kind of astigmatism. The subjects were 153 healthy men and women between the age of 20~80 years. Age comparison, 20 years 1.15D, 30 years 1.23D and above 40 years 0.60D. It was no difference between 20 to 30 years old. But, is decrescent remarkably above 40 years old. Ametropia examined by hypermetropia 1.78D, emmetropia 1.51D, low myopia 1.08D, middle myopia 0.72D, high myopia 0.643D. Myopia increased, Accommodative response amount was expose that decrease. Astigmatism examined by non astigmatism 1.13D, low astigmatism 1.12D, middle astigmatism 0.85D, high astigmatism 0.83D. Astigmatism increased, Accommodative response amount was expose that decrease. The sex and astigmatism type difference appeared with the fact that the result is not a difference.
