이것은 AAA가 일반 누진렌즈와 프리폼 누진렌즈를 비교했을 때 근용부의 시력이 넓어진 것을 제외한 모든 정지시력에서 임상적인 차이가 없었다는 결과와 일치하였다.
This is in keeping with the link between AAA comparing the main-stream progressive lens with the free-form progressive lens, and there was no clinical huge difference in all fixed visual acuity with the exception of the enlarged visual acuity into the near vision area.
