All About the Eye Lens: Functions and Common Diseases

The eyes are responsible for sight. It detects light and sends signals to the brain, so it can recognize the image captured. It is the organ that allows you to experience the beauty and appreciate all the things that surround you. However, the eyes won’t function with a single part. The eye is a complex organ composed of various parts that perform specific functions.

What is the Lens? 

One of the many parts of the human eye is crystalline (lens). It changes the focal distance of the eye, by changing its shape. Hence, the primary función del cristalino is to refract or focus, as the light rays pass through it and to the retina. With this ability of the lens, it creates clear images of the objects at various distances.

The lens also consists of several parts, which include lens epithelium, lens capsule, and lens fiber. The lens epithelium supports the stable functioning of the lens and creates lens fiber for lifelong growth. On the other hand, the lens capsule is the outermost layer of the lens. Meanwhile, lens fibers are long and thin transparent cells that form the lens. 

When you think of it, the eye lens works similarly to a camera. It allows you to capture clear images when in good condition. Unfortunately, like a camera, the eye lens is also vulnerable to diseases and infections. When infected, it will affect a person’s ability to see clear images. It is one of the reasons behind poor eyesight and some eye problems.

What is the Common Lens Problem? 

1. Cataract

The most common eye problem that affects the lens is cataract. It is the clouding of the lens, which results in poor eyesight. This condition slowly develops on one eye, starting from small cloudy speck until it grows and covers the whole eye. Moreover, it can affect both eyes. 

The primary signs of cataract are blurry and double vision, faded colors, seeing halos around light, difficulty in seeing bright lights, and during the night. 

A cataract develops due to aging, eye trauma, exposure to radiation, and genetics. 

When you notice the signs of cataract development, immediately consult an ophthalmologist to prevent it from getting worse. 

2. Presbyopia

Farsightedness is a result of a loss of elasticity of the lens. Hence, the lens could no longer near focus objects and project images. It usually happens due to aging. But the good news is, presbyopia can be corrected.

3. EctopiaLentis

It is a displacement of the crystalline lens that is caused by trauma, ocular disease, systemic disease, and genetics. Most cases of ectopialentis are due to trauma, such as getting a direct blow to the eye or blunt trauma to the head. 

A patient with potential ectopialentis must undergo complete diagnosis and physical examination to identify its intensity. Moreover, the results of the test will determine the type of treatment that is best for the patient.
