 h English (en)==The Anatomy of the Eye==
==== The Cornea ====
<p>The cornea is the transparent surface of the eye which covers the pupil and iris. The cornea functions not only to protect the eye, but it is also the first refractive surface that light goes through on its way to the retina. A healthy cornea contains no blood vessels, so it takes in oxygen from the air to keep it healthy. When the cornea is deprived of oxygen for long periods of time, e.g. overwearing of contact lenses, the body will try to compensate for this by growing blood vessels into the cornea. This can increase the chance of negative immune system responses in the future (causing redness, pain, swelling and eventually damaging the cornea permanently).</p>
<p>The cornea consists of five layers, the epithelium, Bowman's layer, the stroma, Descemet's membrane, and the corneal endothelium. The epithelium is responsible for protecting the rest of the cornea, as is Bowman's layer. The stroma makes up approximately 90% of the thickness of the cornea while remaining transparent. Descemet's Membrane  and the corneal endothelium function to control fluid and nutrient flow between the cornea and the rest of the eye.<ref>Binder, P. S. et al.

==== La córnea ====
<p>La córnea es la superficie traslúcida del ojo que recubre a la pupila y el iris. Además de brindar protección, es la primera superficie de refracción por la que la luz llega a la retina. La córnea carece de irrigación sanguínea en condiciones normales, de modo que el oxígeno necesario lo obtiene del aire. Cabe resaltar que ante la ausencia prolongada de oxígeno, como en el empleo excesivo de lentes de contacto, el organismo trata de compensarla con angiogénesis corneal. Esto influye en la posible aparición de una respuesta inmunológica perjudicial (enrojecimiento, dolor, hinchazón y, al final, lesión corneal irremediable).</p>
<p>La córnea tiene cinco capas: epitelio, membrana de Bowman, estroma, membrana de Descemet y endotelio. El epitelio y la membrana de Bowman protegen los demás componentes de la córnea. El estroma representa 90 % del grosor total en tanto sea transparente. La membrana de Descemet y el endotelio regular el flujo de líquido y nutrientes entre la córnea y el resto del ojo. <ref>Binder, P. S. et al.

 h Korean (ko)==눈의 해부학적 구조(The Anatomy of the Eye)==
====각막(The Cornea)====

각막은 동공과 홍채를 덮고 있는 눈의 투명한 표면입니다. 각막은 단순히 눈을 보호하는 기능뿐만 아니라 빛이 망막으로 가기 위해 지나가는 첫 번째 굴절 표면입니다. 건강한 각막은 혈관이 없으며 따라서 건강한 상태를 유지하기 위해 공기 중으로부터 산소를 받아들입니다. 각막에 산소공급이 오랜 기간 중단되면(가령 콘택트 렌즈를 허용 기간 이상 착용하는 경우), 인체는 각막에 혈관을 자라게 해 이러한 산소 부족을 보충하려 합니다. 이는 부정적인 면역 시스템 반응의 확률을 높이게 됩니다(충혈, 통증, 부종, 결국에는 각막의 영구 손상 등을 유발).

각막은 여섯 겹으로 이루어져 있으며 각각 상피세포, 보우만층, 기질, 두아층, 데스메막, 그리고 각막 내피세포층입니다(The epithelium, bowman's layer, stroma, dua's layer, Descemet membrane and corneal endothelium). <ref>Binder, P. S. et al.
