They detect and process light, and make you see the things arond you. The surface of the eye contains a transparent membrane known as the cornea. The cornea can be damaged if a sharp object or a spark comes to contact with it. This is why wearing protective glasses is important! <br/> <br/> In addition to damage to your corneas,<b> bright and strong</b><span> lights can damage the </span><b>sensory cells</b><span>, which are located in the eye's </span><b>retina</b><span>. </span></p> <br/> <a href="https://peda.net/oppimateriaalit/e-oppi/peruskoulut/vantaa/vkk/21-22/grades-3-6/e53e2/turvallisuus/nsl2/silm%C3%A4n-rakenne/s#top" title="shutterstock_661400689.jpg"><img src="https://peda.net/oppimateriaalit/e-oppi/peruskoulut/vantaa/vkk/21-22/grades-3-6/e53e2/turvallisuus/nsl2/silm%C3%A4n-rakenne/s:file/photo/9897c312474b4db443cbef808bbab8c209b4fb8b/shutterstock_661400689.jpg" alt="" title="The structure of the eye." class="inline" loading="lazy"/></a><br/> <em>The structure of the eye.</em> 2021-08-09T08:10:08+03:00 https://peda.net/id/2a0522def8d 2020-08-05T10:25:14+03:00 <b>Sun</b><br/> The Sun is our nearest star, and it emits large amounts of bright light. This is why you should never look at the sky directly. It is especially dangerous to look at the Sun with binoculars. You can protect your vision during bright days by wearing sunglasses. <br/> <br/> <b>Splatter</b><br/> You should protect your eyes from splashes and splatters. Various chemicals can damage your eyes. Some of them can even lead to blindness if they come to contact with your corneas. If a chemical comes to contact with your eye, you should rinse the eye with plenty of running water. Do not rub your eyes. If you feel a pain in your eyes, you should go see a doctor. <br/> <br/> <b>Splinters</b><br/> You should protect your eyes from splinters. Always wear protective glasses when drilling or sawing things. Metal drills are especially dangerous, as they send sharp metal flakes everywhere. <br/> <br/> <b>Fireworks</b><br/> Protect your eyes when looking at fireworks. A firework can sometimes change its direction and fly directly at your face. 2021-08-09T08:10:08+03:00 https://peda.net/id/2a058329f8d 2021-08-09T08:10:08+03:00 <dl><dt><!--filtered attribute: class="thumbnail"--><a href="https://peda.net/oppimateriaalit/e-oppi/peruskoulut/vantaa/vkk/21-22/grades-3-6/e53e2/turvallisuus/nsl2/n%C3%A4%C3%B6n-suojelua/kaovaot#top" title="shutterstock_200466137_tuli_aurinko_suojalasit_p_p.jpg"><img src="https://peda.net/oppimateriaalit/e-oppi/peruskoulut/vantaa/vkk/21-22/grades-3-6/e53e2/turvallisuus/nsl2/n%C3%A4%C3%B6n-suojelua/kaovaot:file/thumbnail/5151567ed0615da4a38044d3c8acaa859f9d8aad/shutterstock_200466137_tuli_aurinko_suojalasit_p_p.jpg" alt="" title="During the summer months, sunlight can be very bright.
