Recently, some manufacturers developed so-call specialty lenses, eg. Toric lenses, Multi-Focal lenses….etc. However, due to the local regulation constrain, those products are prohibited to do mass media advertising, so the sales and brand awareness of those products are not in good shape.

而近期又有厂商推出所谓的特殊功能隐形眼镜；如散光抛弃式隐形眼镜、老花抛弃式隐形眼镜等等，但碍於国内医疗法规的限制，均不能在大众媒体上作广告行销，而使得产品之知名度不足，所以在商品的推广及销售上都不甚理想。

The using of the fiber-optic detector can decrease the loss of light energy to reduce the unorder light's effect and can make the testing system flexible.

集光系统主要是指用于光能收集和传输的光纤探头，光纤探头的使用一方面使光能损失减少，不受环境杂散光影响，另一方面灵活性大，便于测量样品各个部位的颜色，实现微区测量。

Detected optical instrumentation, optical processing and covers all aspects of measurement, from precision to high precision formation of several major series of dozens of varieties, use of microelectronic technology upgrading of traditional instruments, so that upgrading, such as the ball by the instrument, stray light Miriam, the Center tester, lens fitted Miriam School, T value of measuring instrument, in addition to meet their production needs, are sold at home and abroad, well received by the user's trust and favorable comments.
