In most organizations, computers are an essential tool to get the work done. Though it creates quite a lot of Ergonomic Problems, with the proper equipment, Ergonomic workstation design, proper techniques and working practices, the risk of Ergonomic Problems can be greatly reduced.

The law places certain responsibilities firmly with the employer, however, as individuals there are practical measures we all can and should take to avoid harming our health.

Do you have a condition such as computer vision syndrome (CVS), amblyopia (lazy eye), strabismus (turned eye), or a brain injury?

Vision plays a critical role in our learning, working, and recreation. Vision is more than just having 20/20 eyesight. Vision can be defined as the ability to take in information through our eyes and process the information so that it has meaning.

It is very important that our visual system is efficient because two-thirds of all information we receive is visual. About, 75%-90% of classroom learning comes through our visual system. The visual system is composed of 20 visual abilities. Let’s have a look at these visual abilities:

1. Distance and near acuity : The ability to see clearly at a far distance such as 20 feet, and the ability to see clearly at a near distance such as 16 inches.
2. Accommodation : The ability to adjust focus on objects with various distances.
3. Binocularity: The ability to use both eyes as a team. Proper eye alignment and coordination is necessary so that the eyes can unite two images into one ( fusion), which allows an individual to perceive a single three-dimensional image (depth perception, stereopsis).
4. Oculomotor skills: The ability to quickly and accurately move our eyes. These skills allow us to move our eyes so we can direct and maintain a steady visual attention on an object ( fixation), move our eyes smoothly from point to point as in reading ( saccades), and efficiently track a moving object ( pursuits).
5. Peripheral vision: The ability to see or be aware of what is surrounding us (our side vision).
6. Visual-sensory integration : Once the visual data is gathered, it is processed and combined in the brain with information from hearing ( auditory-visual integration), balance ( bilateral integration/ gross-motor), posture, and movement (eye hand coordination, visual-motor integration).  
7. Visual perceptual skills : The ability to organize and interpret information that is seen and give it meaning is called visual perceptual skills. These information-processing skills include figure-ground, form constancy, spatial relations, visual closure, visual discrimination, visual memory, and visualization.
8. Figure-ground: The ability to recognize distinct shapes from their background, such as objects in a picture, or letters on a chalkboard is called figure-ground.
9. Form constancy: The ability to recognize two objects that have the same shape but different size or position is called form constancy. This ability is needed to tell the difference between "b" and "d", "p" and "q", "m" and "w" are some of these.
10. Spatial relations : The ability to judge the relative position of one object to another ( directionality) and the internal awareness of the two sides of the body ( laterality) is called spatial relations. These skills allow the individual to develop the concepts of right, left, front, back, up, and down. This is needed in reading and mathematics.
11. Visual closure: The ability to identify or recognize a symbol or object when the entire object is not visible is called visual closure.
12. Visual discrimination: The ability to discriminate between visible likeness and differences in size, shape, pattern, form, position, and color is known as visual discrimination. Such as the ability to distinguish between similar words like "ran" and "run" . 
13. Visual memory: The ability to recall and use visual information from the past is called visual memory. 
14. Visualization : The ability to create or alter new images in the mind is visualization. It is needed in reading and playing sports.

The basic skills used to perform tasks such as reading and using a computer are these visual abilities. According to the American Optometric Association, "Among school-age children, vision disorders affect one in every four.

While many of these patients have refractive errors (myopia (nearsightedness), hyperopia (farsightedness), and/or astigmatism) commonly treated by compensatory lenses, some have additional Problems in the functioning of the vision system that are most appropriately treated with optometric vision therapy".

It has been found that about 40% of all Americans have functional vision deficits. Such kinds of vision Ergonomic Problems not only affect an individual's ability to perform tasks, but it can also affect his/her self-esteem as well.

Different visual abilities such as distance and near acuity, accommodation (eye focusing), binocularity (eye coordination/eye teaming), oculomotor (eye movement), peripheral vision, and visual perceptual skills such as figure-ground, form constancy, spatial relations, visual closure, visual discrimination, visual memory, and visualization are required when a person does the reading task.

People who suffer from Learning Disabilities, Dyslexia, or Attention Deficit Disorder, face yet another obstacle when poor visual abilities are present. Sometimes children who are having visual Problems may be mislabeled as Learning Disabled (LD), Dyslexic, Attention Deficit Disorder (ADD), or Attention Deficit Disorder with Hyperactivity (ADHD). 

Visual abilities such as visual acuity, accommodation (eye focusing), binocularity (eye coordination/eye teaming), oculomotor skills (eye movement), eye hand coordination, depth perception, peripheral vision, and visualization are all very important skills that are used in sports such as archery, baseball, basketball, football, golf, gymnastics, hockey, racquetball, shooting, skiing, soccer, tennis, and volleyball.
