在当今数字化外贸时代，谷歌搜索留痕已成为企业拓展国际市场的重要途径。本文将详细介绍眼镜产品出口美国的FDA认证全流程，并分析为何企业需要结合谷歌推广来获取更多海外客户。
一、产品概述与FDA认证必要性
Product Overview & FDA Certification Requirements
眼镜是镶嵌在框架内的透镜镜片，戴在眼睛前方，以改善视力、保护眼睛或作装饰用途。可矫正多种视力问题，包括近视、远视、散光、老花或斜视、弱视等。
Eyeglasses are lens-mounted frames worn in front of the eyes to improve vision, protect eyes or for decorative purposes. They can correct various vision problems including myopia, hyperopia, astigmatism, presbyopia or strabismus, amblyopia, etc.
眼镜出口美国必须办理FDA注册（510k豁免类型）。除隐形眼镜外，包括太阳镜都属于医疗器械I类产品范围。
Eyeglasses exported to the US must obtain FDA registration (510k exempt type). Except for contact lenses, including sunglasses all fall under Class I medical devices.
