Bagian-bagian mata
The parts of the eye we can see from the outside include:
- Kelopak mata (atas dan bawah)
- Bulu mata
- Pupil (central dark part of the eye)
- Conjunctiva (white part of the eye)
- Iris (coloured part of the eye)
- Cornea (clear layer over the iris and pupil).
Other important parts of the eye include:
- Lens
- Retina (back of the eye)
- Optic nerve.
Cara kita melihat
- Light enters through the pupil
- The light passes through the lens, which focuses it on the retina
- An image is formed on the retina
- The image is sent to the brain as electrical signals through the optic nerve
- Ketika sinyal mencapai otak, kita bisa melihat.
To see well, each part of the eye needs to be working properly, and the eyes need to work together.
