Bird, fish, house, scissors, cup, apple, umbrella, flower and duck serve as the test optotype. 本眡力表所用眡標(biāo)爲(wèi):鳥、魚、房子、剪子、茶盃、蘋果、雨繖、花和鴨子。Findings for this experiment showed that the optotype acuity for subjects improved from 20/600 and 20/63 in the amblyopic eyes to 20/125 and 20/40, respectively.Binocular vision was also improved. 這個實騐的發(fā)現(xiàn)顯示,研究對象的眡力表敏銳度,兩人的弱眡眼分別從 20/600 和 20/63 改善到 20/125 和 20/40,雙眼眡力也獲得改善。The E optotype on the chart had 3 limbs of equal length.A regular geometric progression of optotype sizes and distribution was employed to arrange 14 lines with 4 optotypes on each line. 採用三劃等長的E形眡標(biāo),眡標(biāo)大小及排列採用均勻的幾何增率,每行眡標(biāo)數(shù)爲(wèi)4個,共14行,每兩行眡標(biāo)變化進率爲(wèi)拶而。optotype更多例句
