Computer Vision Syndrome: What is the condition of your eyes?

By Cyril Okoye
It is an incontrovertible fact that effectiveness of the other sense organs is dependent to a large extent, on the eye. The eyes, the say, are the windows to the soul.

However, the rise of digital communication in the late 20th century has led to the upsurge of the computer market with various sizes of personal computer {PC} with different nomenclature ranging from notebook, laptop, desktop among others.

It is also a sacred fact that more people work on computer today than before. All aspects of institutional activities and social life such as journalism, business, government, art, health and education are increasingly being carried out in computer sets. That notwithstanding, less attention is always given to the safety of the computer users’ eyes.

Computer vision syndrome {CVS} is a temporary condition resulting from focusing the eyes on a computer display for protracted, uninterrupted periods of time.

It is a serious problem for the people who spend hours in front of computer screens. Staring at a flat screen for hours can cause eyestrain, headache, dry eyes, burning and blurred vision. Apart from physical discomfort, it can have a permanent effect on your vision.

The major cause of CVS is decreased blinking reflex while working long hours focusing on computer screens.

Decrease in normal blink rate of human eyes leads to dry eyes. Blinking helps fluid balance in the eyes and prevents dryness itching. Each time you blink, fluid spread from the tear duct moisturing the eyes.

Long focus puts strain on the ciliary muscles of the eyes. Some patients are faced with inability to properly focus on near objects after a short period leading to a decrease in the accommodative focusing mechanism of the eyes. This can be a setting for early presbyopia..

Some symptoms of  CVS include headaches, blurred vision, neck pain, fatigue, eyestrain, dry irritated eyes and difficulty refocusing the eyes. The symptoms can be further aggravated by improper lighting.
