1 00:00:00,000 --> 00:00:05,340 2 00:00:05,340 --> 00:00:09,180 Hoy vamos a hablar del por qué es importante proteger nuestros 3 00:00:09,180 --> 00:00:12,720 ojos y nuestra visión durante un eclipse de sol. 4 00:00:12,720 --> 00:00:17,280 Nuestra estrella, el sol, es 500,000 veces más brillante que 5 00:00:17,280 --> 00:00:18,390 la luna llena. 6 00:00:18,390 --> 00:00:21,540 Entonces es importante protegerse. 7 00:00:21,540 --> 00:00:25,770 Porque mirarlo sin la protección adecuada es una receta para 8 00:00:25,770 --> 00:00:29,850 lesiones oculares muy graves, incluso la ceguera. 9 00:00:29,850 --> 00:00:32,640 No recomendamos que haga esta demostración en casa, 10 00:00:32,640 --> 00:00:37,650 pero lo que nos va a demostrar es que usando una lente y un 11 00:00:37,650 --> 00:00:42,090 papel, podemos simular el efecto de mirar al sol sin protección, 12 00:00:42,090 --> 00:00:43,980 enfocando la luz solar. 13 00:00:43,980 --> 00:00:45,720 Vamos a ver qué sucede. 14 00:00:45,720 --> 00:00:47,880 Aquí tengo unos lentes de lectura normal de 15 00:00:47,880 --> 00:00:51,000 magnificación, una lupa y un papel. 16 00:00:51,000 --> 00:00:54,000 Los lentes juegan el papel de nuestros propios lentes que 17 00:00:54,000 --> 00:00:56,010 tenemos en nuestros ojos. 18 00:00:56,010 --> 00:01:02,070 El papel juega el rol de la retina que es oscura y enfoca 19 00:01:02,070 --> 00:01:04,260 las imágenes que nosotros vemos. 20 00:01:04,260 --> 00:01:08,220 Entonces aquí vamos a simular lo que sucede, el efecto, 21 00:01:08,220 --> 00:01:11,700 cuando uno mira al sol sin protección. 22 00:01:11,700 --> 00:01:18,060 Entonces aquí tenemos la retina aquí voy a enfocar este lente. 23 00:01:18,060 --> 00:01:21,820 Y vemos que realmente se enfoca de una manera muy brillosa. 24 00:01:21,820 --> 00:01:25,350 Efectivamente ha empezado a quemar el papel. 25 00:01:25,350 --> 00:01:30,840 Aquí tenemos una lupa que obviamente causa un efecto 26 00:01:30,840 --> 00:01:34,950 mucho más catastrófico. 27 00:01:34,950 --> 00:01:39,540 Entonces es muy importante no ver al sol sin la protección 28 00:01:39,540 --> 00:01:40,140 adecuada. 29 00:01:40,140 --> 00:01:42,690 30 00:01:42,690 --> 00:01:46,110 Como vimos, la consecuencia de mirar al sol sin protección 31 00:01:46,110 --> 00:01:47,820 puede ser catastrófica. 32 00:01:47,820 --> 00:01:51,030 De hecho, no tenemos nervios en nuestra retina entonces no 33 00:01:51,030 --> 00:01:55,150 sentimos dolor y podemos injuriarnos de una forma muy, 34 00:01:55,150 --> 00:01:58,900 muy peligrosa si nosotros miramos al sol sin protección. 35 00:01:58,900 --> 00:02:01,050 Y el efecto puede ser cumulativo. 36 00:02:01,050 --> 00:02:02,940 Así que mi recomendación del día, 37 00:02:02,940 --> 00:02:06,950 no miren al sol sin la protección adecuada. 38 00:02:06,950 --> 00:02:14,000
