Cornea: the transparent circular part of the front of the eyeball. It refracts the light entering the eye onto the lens, which then focuses it onto the retina. The cornea contains no blood vessels and is extremely sensitive to pain.
Your eyes are the sensory organs that allow you to see. Your eyes capture visible light from the world around you and turn it into a form your brain uses to create your sense of vision. Your brain doesn’t have sensory abilities of its own. It needs your eyes (and other senses, like hearing and touch) to gather information about the world around you. Refractive errors. These are problems with how you see because light isn’t coming into focus on your retinas correctly. Refractive errors can take many forms, such as focusing too soon ( nearsightedness) or too late ( farsightedness). They can also involve distortions in your sight, like with astigmatism. Jaakkola, MS; Jaakkola, JJ (1 December 1999). "Office equipment and supplies: a modern occupational health concern?". American Journal of Epidemiology. 150 (11): 1223–1228. doi: 10.1093/oxfordjournals.aje.a009949. PMID 10588083. Opening of the eye is not just the result of passive relaxation of the orbicularis muscle but also is the effect of the contraction of the levator palpebrae superioris muscle of the upper lid. This muscle takes origin with the extraocular muscles at the apex of the orbit as a narrow tendon and runs forward into the upper lid as a broad tendon, the levator aponeurosis, which is attached to the forward surface of the tarsus and the skin covering the upper lid. Contraction of the muscle causes elevation of the upper eyelid. The nervous connections of this muscle are closely related to those of the extraocular muscle required to elevate the eye, so that when the eye looks upward the upper eyelid tends to move up in unison. Conjunctiva: a thin layer of tissue that covers the entire front of your eye, except for the corneaTrouble seeing clearly or properly: Blurred vision from refractive errors, or specific vision issues like night blindness or color blindness.
In our opinion, Clinique Skincare products deliver value for money, but take a look at other brands that don’t require you to sacrifice your precious money. Wear protective goggles in classes where debris or chemicals could go flying, such as wood shop, metal shop, science lab, or art. Wear eye protection. Safety glasses or goggles can make all the difference in avoiding eye injuries or damage. While putting them on might seem like a hassle or unnecessary step, they can spare you a lot of pain and avoid irreversible damage. Tears also keep your eye from drying out. Then the fluid drains out of your eye by going into the lacrimal duct (this is also called the tear duct). You can see the opening of your tear duct if you very gently pull down the inside corner of your eye. When you see a tiny little hole, you've found the tear duct. Artificial tears: These eye drops are a lot like your natural tears. They can help treat dry or irritated eyes.

Retina: a light sensitive layer that lines the interior of the eye. It is composed of light sensitive cells known as rods and cones. The human eye contains about 125 million rods, which are necessary for seeing in dim light. Cones, on the other hand, function best in bright light. There are between 6 and 7 million cones in the eye and they are essential for receiving a sharp accurate image and for distinguishing colours. The retina works much in the same way as film in a camera. Versura, P; Profazio, V; Cellini, M; Torreggiani, A; Caramazza, R (1999). "Eye discomfort and air pollution".
