What Are Cataracts In Eyes?
Cataracts in eyes are one of the most common eye conditions that affect the elderly in Malaysia. Before we talk about that, let’s begin by explaining the anatomy or the structure of the eye.
This is how the eye looks like in cross section.
The lens is a clear structure which sits behind the pupil.
It has a capsule or a bag, and is suspended by fine strands inside the eye.
The front part of the eyeball – the cornea, which is the clear & transparent window of the eye, and the lens, are the structures that focuses light to fall on a single point on the retina, called the fovea.
The fovea is the most sensitive area of the retina that is responsible for fine, sharp vision. Allowing our eyes to see small details and enabling us to read small prints.
Therefore, good vision is dependent on clear cornea and lens, as well as normal retina and fovea.
Cataract occurs when the lens becomes cloudy, or more opaque.
