We&#8217;re going to go over those briefly.<\/p>\n<p>We&#8217;ll begin with the outer layer of the eye wall called the sclera. <strong>The sclera is here in the outer wall of the eye, and it is for protection.<\/strong> The cornea, the front of the eye, is actually attached to the anterior portion of the sclera.<\/p>\n<p>Both top and bottom, I&#8217;ve only drawn in a representation of the top. The cornea&#8217;s job is to refract light that enters from the outside in order to put it through the lens and eventually put it onto the retina to allow vision. <strong>The outer part of this 3-tiered system of the wall of the eye is called the sclera.<\/strong><\/p>\n<p>It&#8217;s primarily for protection and anchors and holds the cornea. <strong>The middle layer of the eye wall is called the choroid.<\/strong> The choroid&#8217;s job is basically to keep the inside of the eye dark. You&#8217;re trying to receive light from the outside for vision.<\/p>\n<p>You can&#8217;t have light coming in from all sides. It&#8217;s got to come through a very narrow and small area. Basically, you&#8217;ve got a protective layer, a layer that creates darkness, and then you&#8217;ve got an inner layer. This inner layer is called the retina.<\/p>\n<p><strong>The retina, receiving the light coming in through the cornea, is responsible for communicating color to the optic nerve, therefore giving us vision.<\/strong> Within the retina, you&#8217;ve got both rods and cones. The rods&#8217; job is to take low-light, colorless environments and help us see.<\/p>\n<p><strong>The cones are for our color vision.<\/strong> I happen to be red\/green color deficient. My cones are messed up and I have a very difficult time distinguishing red from green. Christmas tends to be a very boring holiday for me with all these different shades of brown, essentially.<\/p>\n<p>I get asked all the time, &#8220;How do you see colors?&#8221; It&#8217;s hard to describe. I do see colors, but I&#8217;m deficient in being able to distinguish reds from greens. They are very similar to me. Anyway, this has just been a basic overview of the eye wall and its three divisions: The outer, middle, and inner, sclera, choroid, and retina.<\/p>\n<\/div>\n<\/div>\n<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview of the Human Eye!<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"open","template":"","meta":{"footnotes":""},"class_list":{"0":"post-1361","1":"page","2":"type-page","3":"status-publish","5":"page_category-ear-eye-skin-videos","6":"page_category-patient-care-videos","7":"page_type-video","8":"page_domain-science"},"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO Pro 4.9.9 - aioseo.com -->\n\t<meta name=\"description\" content=\"The human eye is a multi-layered complex structure that enables sight.
