Anatomical terminology. [ edit on Wikidata] The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. Along with the anterior chamber and lens, the cornea refracts light, accounting for approximately two-thirds of the eye's total optical power. [1] [2] In humans, the refractive power of the cornea is ...
Kornea ialah bahagian mata lutsinar yang menutupi iris, anak mata, dan kebuk anterior. Kornea bersama kebuk anterior dan lensa membiaskan cahaya, yang mana kornea menyumbangkan kira-kira dua pertiga jumlah kuasa optik mata. Kuasa pembiasan kornea manusia adalah sekitar 43 diopter.
Fungsi utama kornea adalah membiaskan (membelokkan) dan memfokuskan cahaya yang masuk ke mata. Dalam proses melihat , cahaya masuk perlu dibiaskan oleh kornea menuju lensa mata, kemudian diteruskan ke retina. Pada retina, cahaya diubah menjadi impuls listrik untuk diteruskan ke otak, kemudian diterjemahkan menjadi gambar.
Oct 30, 2023 · The main function of the outer coat is to protect structures inside the eye. The cornea contributes to this function by creating a structural barrier that protects the eye from bacteria and subsequent infections. The cornea is also one of the main contributors to the optical power of the eye and acts as an anterior refractive surface for the eye.
Feb 27, 2019 · Cornea Definition. The cornea is the clear front surface of the eye. It lies directly in front of the iris and pupil, and it allows light to enter the eye. Viewed from the front of the eye, the cornea appears slightly wider than it is tall. This is because the sclera (the "white" of the eye) slightly overlaps the top and bottom of the anterior ...
