激光视力装置就是用激光在视网膜上形成Young氏干涉条纹,根据被检查者能分辨最细的干涉条纹的宽度,以此进行换算而测得的视力称为激光视力。激光视力的优点是不受眼屈光与调节的影响,亦不受中轻度屈光间质混浊的影响,即使复杂的屈光异常,不用矫正眼镜及接触镜也可以 Laser vision device is formed by laser in the retina Young’s interference fringes, according to the examinee can distinguish the width of the smallest interference fringes, in order to convert the measured visual acuity called laser vision. The advantage of laser vision is not affected by refractive and adjustment of the eye, nor is it affected by mild and moderate refractive errors. Even complex refractive errors can be corrected without glasses and contact lenses
