VISUAL IMPAIRMENT
Visual impairment is a disease in vision and partial sight that may lead to blindness. It is an abnormal visual behavior that affects people to demonstrate a decrease in visual acuity. There are many factors that may affect a person from having this kind of visual abnormality sometimes a person may be genetically born to have such visual impairment.
A person who has been born with this kind of visual acuity may also be physically weak in mobility and intellectual capacity when they grow up therefore they are definitely required for an extensive medical attention as early as possible to be able to apply an immediate cure to their vision. Sometimes inborn vision impairment may not be cured at all by any medical surgery because of complication or it may vary from different type of severity and therefore medical operation may be crucial to the extent of total blindness or complication that may lead to death.
Most of the times less severe visual impairment can simply be cured by using an eye glasses or contact lenses. There are different types of visual impairment according to level of severity; firstly is the partially sighted person who can see but with less vision, they can sometimes depend on their own to mobilize and grasp things independently but may require a special assistance when reading because of small details that they may not easily identify while reading. Second is the low vision individual which suffers a more serious visual problems than a partially sighted person, they may need a Braille system when reading although there is a slight visual transparency in their vision when nearer. Next is the legally blind person who cannot see things clearly near or far but just a reflection or abstract images. Lastly is the totally blind person who has no vision all. This kind of blindness is usually incurable and may require a Braille system to understand and read objects.
One eye blindness is another form of visual impurities that can create an imbalance and abnormal vision to a person who suffered from this kind of abnormalities but nevertheless they can still be as normal in conceptual framework of development such as learning and reading. Conceptually a person may also suffered from deaf blindness or an umbrella effect that may cause a person to be deaf and blind at the same time children and adult alike can be susceptible with this visual disease depending on their progression or experiences. It can also be inborn or hereditary.
Basically a person with this kind of visual imperfection may be need to a thorough attention in learning from various institutions and schools for the blind so that they can be given a special treatment and gradually assess their consistency in learning. Their performance in school may or may not be like of those ordinary students depending on their physical and spiritual capacity and interest to learn but basically it is an understandable behavior that visually impaired students are expected to learn slowly because of their situation. Braille system and cane stick has been very helpful in their learning capability that should always be available on their side in school or even at home if possible.
A person with a regular 20/20 vision can also be affected in this kind of disease accordingly and there are many reasons why people can suffer from this impairment.
· Infection from bacteria can cause visual impurities, especially from busy streets and construction sites where there are dangers in visual suffocation.
· Dust, moisture and any other harmful chemicals and objects that are large enough to enter into our eyes can ruin our vision.
· Cataracts that shows a cloudy vision due to overuse of vision. This condition can be surgically treated with the use of eye glasses and or contact lenses.
· Amblyopia which is caused by misaligned eyes that causes the brain to interpret images in unlikely manners.
· Macular degeneration of retina, a part of the eye that weakens its condition that usually occurs because of aging, vices like smoking and over exposure to sunlight.
Ophthalmology and other medical professionals that is concerned in eye care should be sought if a person experience any of the above visual impurities so that they can be given professional attention and treatment that is legally applicable to their conditions and can manifest cure rather than neglect or self medication that is basically dangerous. A person who self medicate can put themselves in a more dangerous condition when not properly guided by applicable treatment.
