Amblyopia should be suspected as a contributor to decreased visual acuity when ( )
A: Hyperopia ≥ +5.00 DS
B: Myopia ≥ -10.00 DS
C: Astigmatism ≥ 2.00 DC
D: Difference of clyindrical diopter ≥ 1.00 DC
A: Hyperopia ≥ +5.00 DS
B: Myopia ≥ -10.00 DS
C: Astigmatism ≥ 2.00 DC
D: Difference of clyindrical diopter ≥ 1.00 DC
举一反三
- Visual acuity decreasing is myopia
- Visual acuity decreasing is myopia A: 正确 B: 错误
- 在67cm处检影,当加-1.50 DC ´120时,各个方向的影动都被中和,则此被检眼应戴眼镜度数为( )。 A: +1.50 DS/-1.50 DC ´120 B: -1.50 DC ´120 C: -1.50 DS/-1.50 DC ´120 D: +1.50 DC ´120
