Eyesight



ATTENTION!
It is impossible and useless to try to rank childhood disorders. Every disorder must be taken seriously and parents should be educated about them. With regard to vision, it is extremely important that a physician or opthamologist diagnose the disorder and supervise the treatment.
What are vision problems?
Childhood vision problems can usually be traced back to kindergarten age and to a source that could have been eliminated if recognised in time. We are often less concerned with our eye muscles than any other muscle in the body. These muscles need training much like other muscles in our body. Since we never train them, we cannot really relax them either. In the majority of the cases, disturbances in vision are caused by the overworking of the eye, which results in eye muscle tension. Physical and mental relaxation is the only way to release muscle tension. When the eye is no longer strained, it will improve and work better. In other...
How often do they occur?
Currently, 20% of the population is nearsighted, 30% is farsighted, and these percentages are increasing. Between 30% and 40% of all people who use computers for 3 to 4 hours daily will eventually have eye problems.
At what age does it develop?
During the last decade, the number of televisions and computers in homes has tripled. We are being told everywhere about the strain these types of technologies put on our eyes, and yet, the average amount of time spent in front of the monitor continues to increase. Unfortunately, vision problems can develop at any age. Our eyes are one of the most important sensory organs and living without them is very hard. That is why preservation of their health is crucial.
Do vision disturbances correlate with other disorders?
Yes. Incorrect posture can cause deterioration of vision. Neck muscle cramps cause tension that affects our eyes. Hanging our heads causes the position of the eyes to change. These bodily changes cause the eye muscles unnecessary strain and can lead to vision disturbances. Another major risk factor for vision problems is a vitamin poor diet.
What are childhood cockeye and lazy eye?
Cockeye (cross-eye) disorder is caused by the unsystematic development of the muscles that move the eye and is often accompanied by farsightedness. To accommodate this problem and prevent blurred vision, the child's brain disconnects the weaker eye from the visual pathway by shifting the axis of the weaker eye a few degrees. Cockeye disorder can be treated by covering the stronger eye with a patch for a period of time to require the weaker eye to get stronger. Without this treatment, the stronger eye will get stronger while the weaker get progressively weaker. If the two eyes cannot work together in harmony, spatial vision will fail...
What are the solutions to vision problems?
Again, prevention is important. Your child has to learn how to train and relax the eye muscles. The FITFIVE system gives your kids very precise exercises that teach them how to use these muscles effectively. Eye exercises are not enough. If bad vision and bad eye habits persist, they must be corrected. FITFIVE provides you with precise details on how to do this successfully.
What are the emotional, mental and spiritual causes of vision disturbances?
90% of vision problems is mental/ spiritual and only 10% is physical. That is why the cause of every disorder should be sought within the individual. A number of small accidents can affect children but most of these problems are never voiced, since children often are not even aware of what exactly causes the pain. More often than not, they are not aware what happens inside their bodies and minds. This is the cause of many problems; suppressed tension can lead to anxiety and eventual development of a disease. Psychological research shows that a majority of people store traumas suffered during childhood as negative energy in the...
What are the physical causes of vision disturbances?
Bad vision develops in a large percentage of people as a direct result of poor vision habits. Situations that are not ideal for clear vision These by themselves do not cause vision problems given that they do not damage the function of a healthy eye. Nevertheless, in an eye that does not function correctly to begin with, these situations could often lead to deterioration of the eye muscle. Overworked, overstressed In today's fast-paced world, we tend to pay attention to our health only when we suffer the severe consequences of its deterioration. Unfortunately, this tendency is true for our children as well as adults....
Why are TV and computer screens harmful to the eyes?
The eye is built to see in three dimensions. A flat monitor only offers two dimensions. Muscles exert only a minimal amount of exertion when the eyes are fixated on a monitor screen. We blink 15 times per minute under normal circumstances whereas in front of a monitor we only blink twice. What a difference! It is no wonder that our eyes get dry. Here is another interesting thought: the screen emits light thus it is a sort of light source. Is there any other animal in the world that is able to stare into the light six to eight hours per day? Furthermore, the electromagnetic field of the monitor screen attracts dust particles that in turn...
What are consequences of vision problems?
Visual disturbances pose a very complex problem. The greatest disadvantage of glasses and contacts is that they fix the deteriorated condition of the eye at the current level. Instead of the muscles working toward improved vision, they adapt to the glasses or contacts. This effect causes the eye muscles to become tensed even more. On the other hand, without glasses, the child will squint and put even more strain on the eye muscles. Moreover, leaning forward also results in bad posture, muscle cramps, decrease blood flow to the eyes, and further damage. Ultimately, squinting creates a vicious cycle which resulting in declining...
Why do children want to wear glasses?
A big danger is when kids who do not physically need glasses start wearing them. The reason could be that the child simply craves attention and as a result complains of his or her vision. Another reason kids want to wear glasses can be the desire to look like an adult or possibly to get people to feel sorry for them. These could be reasons for kids to feel the need to get glasses. Glasses can make people feel as if they are able to hide from the world and, therefore, glasses might be viewed by some as a sort of safe haven. If the family has many members who wear glasses, the child may simply want to fit in with the family and not to...
What are the advantages of healthy vision?
There is an endless list of advantages but some of the most important ones include: The child will be more successful in school and visual problems will not affect his or her schoolwork. It is more likely that the child will be able to choose a sport activity that is best suited for his or her personality. It will be easier to choose the right career. The child will not have to bother with glasses or contact lenses. Bad vision will not affect their choice of a partner or friends; furthermore, the child has more self-confidence. The child is more likely to have a positive outlook.
How do vision problems develop? A little anatomy
The globe of the eye is located in the orbital cavity. It has a spherical shape with an average diameter of 0.94 inches (24 mm) and a weight of 0.25 oz to 0.28 oz (7 to 8 grams). The eye has three layers: - An outer layer called the sclera; - A middle layer called the choroid; - An inner layer called the retina. The sclera is a tough white connective tissue capsule, which is anterior of the transparent cornea and protects the eye from injuries. It is opaque so the light can only enter through the pupil. The choroid ensures the blood supply of the eye. The pupil is located in the centre of the iris, and behind it is the lens of the...
The visual process
Light rays first cross the cornea. The pupil determines how much light can enter the eye. In darkness, the pupil dilates to allow more light to enter. The lens collects the incoming rays and focuses them on a point in the retina. For optical reasons, an upside down image is generated from the original picture. This image is then transported down the optic nerve to the brain’s visual centre, where the actual image is constructed.
The eye muscles
Six muscles move the eye. The two oblique eye muscles are responsible for sideways turn. The four rectus eye muscles are responsible for vertical movements.
