صحّة العين

Eye health refers to the condition of a person’s eyes.

If a person’s eyes are not healthy, it affects how well their eyes can work.

أجزاء العين

The parts of the eye we can see from the outside include:

• الجفنَين (العلوي والسفلي)
• الأهداب
• 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.

كيف نرى

• 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
• عندما تصل الإشارات إلى الدماغ، يمكننا أن نرى.

To see well, each part of the eye needs to be working properly, and the eyes need to work together.
