NO
To investigate the efficacy of divergence on near visual function
Efficacy
Objective refraction
1. Near binocular visual acuity
2. The rate of variability of pupil diameter
3. The presence or absence of blurred vision
Interventional
Single arm
Non-randomized
Open -no one is blinded
Uncontrolled

Prevention
Device,equipment |
Divergence eye movement with base-in prisms.
The subjects were induced into 4 degrees of esophoria (0~2, 4, 8, 10~16 prism E) by putting the base-in prism. We investigate the objective refraction, near binocular visual acuity, pupil diameter, subjective symptom, while the subjects fuse an accommodative target at near fixation in each degree of esophoria. Prism wearing time of each stage is about 10 minutes. Measurement time is about 45 minutes in total.

Visually healthy young subjects who have corrected visual acuity 1.0 or better without ocular diseases.
Volunteers who have hyperopia, manifest strabismus, intermittent exotropia, post-refractive surgery.

Difference in the accommodative lag was observed significantly 0 PD E and 10-12 PD E. A correlation was observed between the angle of esophoria and the NBVA, and between the accommodative lag and the NBVA. There was no correlation between the angle of esophoria and the rate of VPD.As the degree of divergence amplitude increased, the accommodative lag increased, and the near binocular visual function decreased.
