炎热的夏天,强烈的太阳光特别刺眼,于是许多人戴上太阳镜以遮挡阳光对眼睛的直接刺激。的确,阳光中含有大量的紫外线和红外线,这些射线较长时间直接刺激眼睛,可以损害眼角膜和晶状体,使眼睛红肿,甚至导致白内障的发生。因此,戴太阳镜是必要的,尤其是长时间在户外工作的人,如交通警察、地质勘探队员等更应选戴太阳镜来保护眼睛。 Hot summer, intense sunlight is particularly dazzling, so many people wear sunglasses to block the sun’s direct stimulation of the eyes. Indeed, the sun contains a lot of ultraviolet and infrared rays, these rays directly stimulate the eyes for a long time, can damage the cornea and lens, the eye redness, and even lead to the occurrence of cataracts. Therefore, wearing sunglasses is necessary, especially for a long time outdoor work, such as traffic police, geophysical team members should also wear sunglasses to protect the eyes.
