Single vision lens 要么近视，要么远视

Multifocal lenses 近视远视都有

The most commonly prescribed spectacle lenses are 'single vision' lenses. Single vision lenses have only one power in the lens and allow you to see clearly in either the distance or at near. Most younger people who wear spectacles have single vision lenses but as people get older, they gradually lose the ability to alter the focus of their eyes ('presbyopia'), and usually some time between the ages of 40 and 50, they develop a need for corrective lenses for both distance and near vision. They can use two pairs of single vision spectacles and change them as necessary or, alternatively, one pair of multifocal lenses. As the name suggests multifocal lenses are lenses which have more than one power, allowing the wearer to focus at more than one distance.

那么这里的眼睛片，也可以跟国内的一样，超薄加膜之类的？是否需要加钱

一般SINGLE VISION的价钱$75，BIFOCAL$140,一般的MULTIFOCAL价钱$249,比较好的MULTIFOCAL叫FREEFORM价格$495左右，加磨镜片肯定是另外加钱的，例如你的镜片要TINT,TRANSITION,ANTI-REFLECTION,POLARISED价格都不一样^-^
