The magnification of the Zeiss type of fundus camera depends, except for the case of emmetropy, on the camera-to-eye distance. Its relative variation is equal to the product of the patient's ametropia and the difference in the camera-to-eye distance. Moreover, magnification is also affected by changing the diopter range scales on the camera.
蔡司型眼底照相机的放大倍率，除正视眼情况外，取决于相机与眼睛的距离。其相对变化等于患者屈光不正度数与相机到眼睛距离差异的乘积。此外，改变相机上的屈光度范围刻度也会影响放大倍率。
