各位英语达人请帮我写一些介绍近视境和墨镜,太阳镜的英文,

近视镜：Myopia lens
Myopia (from Greek:μυωπία myopia near-sightedness),also called near- or short-sightedness,is a refractive defect of the eye in which collimated light produces image focus in front of the retina when accommodation is relaxed.
墨镜=太阳镜：sunglasses
Sunglasses or sun glasses are a visual aid,variously termed spectacles or glasses,which feature lenses that are coloured,polarized or darkened to prevent strong light from reaching the eyes.In the early Twentieth century they were also known as sun cheaters (cheaters being an American slang term for glasses).
