As computers become part of our everyday life, more and more people are experiencing a
variety of ocular symptoms related to computer use. These include eyestrain, tired eyes, irritation,
redness, blurred vision, and double vision, collectively referred to as computer vision syndrome.
The effect of CVS to the body such as back and shoulder pain, wrist problem and neck pain.
Many risk factors are identified in this paper.
Primary prevention strategies have largely been confined to addressing environmental
exposure to ergonomic risk factors, since to date, no clear cause for this work-related neck pain
has been acknowledged. Today, millions of children use computers on a daily basis. Extensive
viewing of the computer screen can lead to eye discomfort, fatigue, blurred vision and headaches,
dry eyes and other symptoms of eyestrain. These symptoms may be caused by poor lighting,
glare, an improper work station set-up, vision problems of which the person was not previously
aware, or a combination of these factors. Children can experience many of the same symptoms
related to computer use as adults. However, some unique aspects of how children use computers
may make them more susceptible than adults to the development of these problems.
In this research we took the adult and children as a case study, questioner are made to rich this
research and finally some preventions are listed to immune from the impact of computer..
The biometric-based keys generation represents the utilization of the extracted features from the human anatomical (physiological) traits like a fingerprint, retina, etc. or behavioral traits like a signature. The retina biometric has inherent robustness, therefore, it is capable of generating random keys with a higher security level compared to the other biometric traits. In this paper, an effective system to generate secure, robust and unique random keys based on retina features has been proposed for cryptographic applications. The retina features are extracted by using the algorithm of glowworm swarm optimization (GSO) that provides promising results through the experiments using the standard retina databases. Additionally, in order t
