Biography: Luciana Elsa Acosta Guemes
The invention of computer technology has revolutionized and benefited the society but at the same time has caused many symptoms related to its use. Computer Vision Syndrome (CVS) is a widely spreading and epidemic problem among professional and ordinary computer users. Among them, we can find eyestrain, irritation, redness, dryness, headache, neck and back pain, tired eyes, blurred vision and double vision. This group of symptoms is known as Computer Vision Syndrome (CVS). Some of the mechanisms that lead to computer vision syndrome are extraocular or ergonomic mechanism, accommodative spams mechanism and ocular surface abnormalities mechanism. However, the major contributor to computer vision syndrome symptoms appears to be dry eye. The visual effects of the computer display characteristics such as lighting, brightness, resolution, radiation, glare and display quality all are known factors that contribute to computer vision syndrome. Prevention and treatment require a multidirectional approach combining ocular therapy as well as adjustment of the workstation. Among modification in the ergonomics of the working environment, we can find proper lighting, anti-glare filters, ergonomic positioning of computer monitor and regular work breaks, in order to improve visual comfort. Also, patient education and proper eye care are crucial in managing computer vision syndrome. For example, lubricating eye drops and special computer glasses help relieve ocular surface related symptoms. These symptoms are usually temporary and disappear at the end of the working day although some of them may experience continuity of symptoms after work and take a chronic state.
