But at a distance, images focus at a point in front of the retina… making distance vision blurry.

但在远处，图像集中在视网膜前面的一点，使远距离视觉模糊。

This will result in excessive and continuous use of intraocular (ciliary) muscles in order to keep the image focused on the retina, resulting in pain.

这将导致过度和持续地使用眼内（睫状肌），以保持图像聚焦在视网膜上，导致疼痛。
