角膜、晶状体与房水和玻璃体共同构成眼睛的屈光系统，它们通过对光线的折射使外界的物体成像在视网膜上。
The cornea, lens, aqueous humor, and vitreous humor collectively constitute the refractive system of the eye, refracting light to form images of external objects on the retina.
生物测量仪一般应用超声或光学方法对眼球的结构参数进行测量，获得角膜曲率K，并可以获得更多的眼球参数。
Biometers generally employ ultrasound or optical methods to measure the structural parameters of the eye, obtaining corneal curvature (K) and additional ocular parameters.
框架眼镜是比较简单且安全的屈光不正矫正方法，可以矫正包括散光在内的屈光不正。但如果存在较高屈光不正、屈光参差等，就会存在较大的物像变化、双眼成像难以融合、视觉质量差等视觉问题。
Wearing glasses is a relatively simple and safe method for correcting refractive errors, including astigmatism. However, if there are high degrees of refractive errors or anisometropia, visual problems such as significant changes in object image, difficulty in binocular fusion, and poor visual quality may occur.
