Frequently Asked Questions
The human eye is a complex organ composed of several parts including the cornea, iris, pupil, lens, retina, and optic nerve. Each part plays a vital role in processing visual information.
Light enters through the cornea and passes through the pupil. The lens then focuses the light onto the retina at the back of the eye, where photoreceptor cells convert it into electrical signals sent to the brain.
Photoreceptors are specialised cells in the retina known as rods and cones. Rods are responsible for vision in low light conditions, while cones detect colour and detail.
Myopia (nearsightedness) occurs when light focuses in front of the retina due to an elongated eyeball. Hyperopia (farsightedness) happens when light focuses behind the retina because of a shorter eyeball.
Glaucoma is a group of diseases that damage the optic nerve due to high intraocular pressure, leading to gradual loss of vision if untreated.
