Types of visual impairment

The visual disability is, unfortunately, quite common. When we hear about it, the first thing we think about is blindness, which is the total or almost total lack of vision. But there are many different types of visual impairment, each with its particularities, with its symptoms and with its way of developing. Of each of them, however, it is possible to cope with a normal life with the appropriate help and support from the people surrounding the affected person, as if they were locksmiths helping them to open the door apparently closed by disability. Here we will see some examples of these conditions.


This condition produces a tunnel vision, in which the peripheral vision diminishes with time. The “hoop” of vision, gradually becomes smaller and smaller until the affected loses completely the ability to see clearly in the full extent of their field of vision. It is, as we see, a degenerative condition that, however, has treatment if it is attended to in the first stages of its appearance. It is important, therefore, to be always aware of all the signs and the way in which the vision can be affected over the years.

Macular degeneration

This type of degeneration of the sense of sight is one of the most common since it is what occurs with age. The process is inverse to what we have observed with glaucoma, since peripheral vision remains and what begins to distort over time is the vision towards the center of the visual field. This greatly affects the performance of activities that require the concentration of sight, such as reading, manual activities, etc. Although it is a condition that occurs without pain, it is quite common, so it is recommended to perform periodic eye exams when you reach a certain age.
Its name comes from the visual sensation that this condition produces in the person who suffers it. It is as if his vision is permanently distorted by a fall of water. This can greatly blur the vision or even make it almost completely lost. This condition can be accompanied by an excess of sensitivity to light and is quite common from a certain age, so, as in all cases, it is recommended to make continuous checks.

Diabetic retinopathy

This condition of the sense of sight is related to diabetes. The damage produced by this disease to the circulatory system can affect the sight, producing reduction in visual acuity, headaches or black spots in the visual field. It is degenerative and can lead to loss if it remains untreated.
As we have seen, in most of these and other conditions, one of the most important things is to always be attentive to the symptoms to seek help as quickly as possible. Only then we will be able to stop the deterioration of the sight that comes with them and thus we will be able to enjoy many more years of quality of life.

Live example of success without limitations

Every time that society becomes more cultured, we learn that there are no such differences among human beings, or rather that physical differences are what makes us unique, being an advantage, a gift and not something negative. He who is born with a disability is usually hidden, repressed or limited, thus increasing his limitation.

To people who have suffered accidents and have lost some sense, those who have been born in some situation of disability should be included in the social environment, just like the rest. They have not asked to be granted the disability to add others that society imposes, when they can not join the school, a job, make friends, get couples, generate wealth or move wherever they want.

In the world, there are samples everywhere that the only limitation is the person in their mind, when they do not feel that they do not have a place in the world, that they can do what most makes them happy or that they have the same rights as the rest.
Therefore, it is our social commitment, to show that they do not need anyone to help them live because they can do it alone, that they are not helpless that they can take care of themselves, that someone else already tried and I achieve it with perseverance.

Singers, pianist, drummers …

The list is quite long of living examples of people who with a disability of birth or acquired over time, continued their life with normality, making art, enchanting their audience, being happy and making happy by means of what most like.

This list includes: Stevie Wonder (Blindness), Ray Charles (Blindness), Rick Allen (missing an arm), Nick Vujicic (missing all limbs), Frida calo (dysmetria in his right leg), Jamie Brewer (Syndrome) of Down), Ludwig van Beethoven (Deafness), and so the list goes, with dancers who lack a leg or an arm, but which do not show on stage because their movements are neat.

Maximized senses

All the senses maximize their power when necessary. It can happen to us at some point. People with some disability help their other senses to replace the one they lack, they become more skilled at hearing, for example, when they are blind.

People who lack some limb have a much better balance than those who do not have physical disabilities, because they have had to be skillful, accentuating then that the disability is mental, when you do not want to assume.

Another approach to life

The world works to offer options that make them stand on their own, without having to depend on anyone. Locksmithing, like other branches of life, works to make products more accessible to everyone, that are easy to use, or adapt to certain conditions, such as voice commands, touch screens on locks, or door closers or switches in the doors. The different dimensions of products that locksmiths make the spaces more secure and accessible improve every day.

What is inclusive art about?

It has become clear that art does not exclude anyone, but quite the opposite. The different art forms leave the wide open space so that it can be perceived through any of the senses. Discrimination has been left far behind, to those who may still think that a blind person can not go to the cinema, or make a statue or perceive it, shows its own limitations and not the person who has the physical disability.

Throughout the world, formidable efforts are made so that others who have lost vision can enjoy the pleasure of a work of art, or involve those artists who have been limited by any natural or accidental circumstance to observe them.

There are many claims by art regulars that art is a feeling that is expressed through a work, that art feels with the spirit then because he who does not see, because he could not perceive it. It is obvious that the media can be different but it is possible to create projects of fascinating inclusion so that there are fewer and fewer people out of the magnificent art.

Inclusive project

Adapting for the world for those who have some physical disability, it is not so difficult, it is necessary to free oneself from one’s own limitations, to be able to place these people in the shoes, perceive the world as they perceive them and get the forms so that they can get involved in art.

In the different inclusive projects, it is necessary to be able to have information about the most visually impaired and invite them to live the experience. These people can perceive the forms of a sculpture, through their hands, perceive, size, texture, shape and even smells, without needing to be able to see them.

The works can be adapted so that they can be touched by the visitors to each museum and even include smells to increase the lived experience. There are more and more art centers in inclusive projects, which can not only be attended by the blind but also by anyone who wants to perceive the experience through other senses.

Blind artists

Depending on the type of work, blind artists can give us the possibility of knowing how they perceive life through art. The forms of art manifest them in a different way, where only the meaning of the work could not be observed, the message that is wanted to be transmitted, but to value the process of creation.

On the other hand, there are the artists who create for the disabled, it is to adapt their work so that it can reach these people in a different way, such as the cinema edited for the blind, the sculptures that are played, or an assisted dance group.

Other senses to perceive: Cinema for the blind

Each city should have a cinema for the blind, which can not only be perceived by them, it can be fascinating to live the experience of seeing a film adapted to feel it without seeing it with their eyes, but the work allows your imagination to do all the work of creation, through sounds, stories and movements of the environment that give an additional value of superior imagination.

The senses of a visually impaired People

A visually impaired is a person who goes through many problems in his life. It is not only not seeing, but they have to deal with social stigmas, together with social and labor inequality. Despite the inequality that they have, they are responsible for coping with the situations that arise.

We know that sight is lost, but how can we do with the other senses? What happens to them? These, when the loss of one of these occurs, they try to compensate for the lack of this and they manage to develop more than normal.

The touch

This is one of the most important senses. Through this we are able to perceive the pressure, the shape of the objects that exist, their hardness, their softness, among others. But through this they can also examine, feel, and thus be able to know different beings and objects, while in their mind they assume the form they are touching.

Bearing this in mind, we can say that touch is one of the most used tools by the blind because through this is that they can perform readings, in addition to writing on a computer keyboard or playing musical instruments, all this with the hands. Braille is the special language that blind people have, and it is used specifically for this type of person.

The audition

This also becomes one of the most primordial parts that accompanies them, because through the so-called echolocation they can realize where there are obstacles, walls, among other things, thus being able to avoid them.

It is necessary to say that this is a primordial part for the security of themselves. The use of a cane is paramount, because it allows them to determine the sound waves when they hit an object, and thus to know what they have in front of them, in addition to what surrounds them.

For your safety it is also good to have a dog companion, who can guide you when you have no one who can do it for him. They are a very big help because they can take care of all those incidents that may disadvantage them, as well as any criminal who wants to take advantage of their condition.

Echolocation is part of the life of these individuals, and the younger the vision (of birth) is lost, the more this part of the sense of hearing develops.

The sense of smell

Through this they obtain different information that they can not with the other senses. Through this they perceive the smells that exist in the environment, so they can associate the smells with the objects that are in a room, for example.

In addition to this, they can also distinguish between the type of food they have in front, if an object is old or new, in addition to distinguishing people through the smell they have.

The set of meanings that we have happen to be in the background, to be the protagonists. These show improvements, that is, our body tries to survive despite all the obstacles we have and tries to adapt to what we have.

You can smell the colors

Suffering from blindness is devastating in any case. Whether it is a condition from birth, as a child or as an adult accident, whatever the case, the person can take two options to try to make his widow as normal as possible or let himself be dominated by the tragedy.

Of course, coping with any tragedy will depend on the emotional strength of each person. Technology has launched to the market devices that make the lives of the disabled related to the most independent vision, likewise society creates spaces that are more adapted for everyone.

But beyond the help they can receive from others, there are special and wonderful conditions that are generated in people who fail some of the senses. It is wonderful the history that is known with the domain or aggrandizement of some sense when another fails.

It is wonderful, to see a deaf dance, to see them perceive the sound with another meaning. Or even more incredible is to see how a blind person knows a color when they smell the surface. Do you find it incredible? But it is very true, the human brain seems to generate other capabilities when needed and these are easily demonstrable.

You know what is Synesthesia …

This ability of the brain to increase the power of other senses has a name. These new qualities are called synesthesia, their explanation can get confused. There is a very special way of perceiving the exterior with a meaning that is not commonly used.

According to science there are three types of synesthesia:

  • When a word is pronounced, it can be associated with an involuntary sensation of taste.
  • When any sign, letter or number is observed, the brain relates it to a specific color.
  • When certain music is heard, the synesthetes’ brain turns it into colors.
  • Devices for the senses

To overcome the limitations of vision in a technological way, electronic equipment reading rings have been manufactured, human movement sensors have also been created that generate sounds or optical readers that capture colors and convert them into sound.

Although the latter was created to take the colors of nature and use it in graphic design, it was also a fantastic application to give you the alternative of knowing what color is in front of you.

Unexpected synesthesia

But even more interesting is knowing that some special people have been able to find a gift to perceive color, just by smelling its surface. This synesthetic condition may seem like an act of magic, but the brain hides incredible mysteries of which it is capable when the person wants to achieve it.

They can also feel the sound with their skin, it is said through the vibrations of sound. Although the most incredulous believe that it is a reflection of creating on the need for meaning, it has been demonstrated that this condition is demonstrable, constant, lasting over time.

Not all people can achieve this superior sensory abilities, because it is related to a very high emotional level, which some are not willing to overcome due to the visual accident situation itself.

Progress of science

People who were born with the difficulty of seeing or are completely blind lived resigned to that reality never changing. Thanks to the latest advances in science and technology, this state of blindness can change. In addition, having to live with disability, alternatives have been created to make life easier and independent of others because they can not have vision.

Life does not have to be so hard, there is always hope for the cure of diseases and society is becoming more responsible to open a place for the disabled and include them in all our activities to the extent possible.

It is possible that this information interests you because someone very close to your life, is in this situation. You do not have to cross your arms, you have to investigate the latest developments and hope that they will be perfected as soon as possible. However, they should not despair and undergo tests or treatments that have not been medically guaranteed because the damage could be worse, not only with blindness but with any medical treatment.

If I was born blind, I will die blind …

Not necessarily. When you are together with a person suffering from a vision disability, you can not resign yourself to their condition, without first seeing doctors offering alternative healing. This is what should be transmitted to patients, if it refuses to consult a doctor.

Wanting to be part of current life, the technological world can act as a motivator to find the cure. The psychological treatment for receiving medical help or resigning to the condition of blindness is elementary for the individual and for his relatives.

It is necessary to know that at least three treatments are known worldwide and good results are bet. The treatment with Stem Cells must be very careful because the implantation procedure of stem cells in the eye are not properly regulated and unapproved clinics end up being a fraud.

The proper procedures results in efficient results in most patients. The artificial Retina and Bionic Eye suppose a more complex intervention of the patient but with great effects after beginning to detect the vision.

Technology for the blind

Do not sit back and wait for scientists to find the solution to blindness. Meanwhile the technology makes available:
The coarse for obstacles, innovative sensors have been placed, in a cane similar to the traditional ones for the blind, this sends signals to a Smartphone of the proximity distances evaluating as dangers or as a protected area option.

There is also the reader ring that can be used in Tablet or electronic devices of the time. There are also various applications that shoot a photo informs you the characteristics of what is facing. Some similar applications are used to detect colors.

Without forgetting the screens that form braille code in reliefs on its surfaces. For children, there is a variety of toys, although the books printed in 3D, make them feel the forms of what is narrated by making reading very interactive.

Integration of the blind to marketing

Companies try to exploit any niche that is not being addressed. However, the needs of people with visual impairment or total blindness, although it is a bit complicated, have a noble and interesting meaning for those who want to focus their products on humanitarian footprints in the world.

That you can not see what you have around you does not mean that you are not alive. Similarly, the boom of social networks also touches anyone regardless of the limitation. In a plausible way, the companies are adapting with much success the most common electronic equipment, the products with language for the blind and alternative activities.

Marketing can reach blind people directly without having to do it through the perception of their intermediaries. To sell something to people with visual disabilities, it is necessary to fall in love with the senses of their caregivers, rather than the consumers themselves.

But this reality can change effectively by adding devices such as the reading ring, Braille labels in everyday products or adapting spaces for independence of movement, such as movie theaters or shops in general.

Reader ring

The uses of this ring is a bit controversial. It is a device in which the blind introduce the finger and this reproduces the voice from where it is standing. It has been effective in reading audiobooks, but what sense could it have if the reproduction of the work by means of voice commands is enough.

This reader ring certainly has to be polished and look for more functional operations although the first step was already taken in offering a more novel weapon of how to read a technological equipment. For much more interactive applications it could be overwhelming, unless you have previous information on how the page is organized.

Tagged with Braille

One step more to the independence of others to go shopping for their favorite products, at least in the area of ​​personal hygiene. They are labels or packaged in braille language, without having to ask for help you can try which one you want to carry.

Now foods that are not packaged is more complex this arrangement because it is not convenient to touch both for hygiene reasons, so the sense of smell can help. There is still a long way to adapt a world for them.

Cinema for the blind

One of the most surprising proposals for people with visual disabilities are movie theaters with adaptations for the blind. The seats are full of sensors that emit sounds and vibrations bringing them closer to the reality of the cinematographic work.

Although only the productions are adapted to be narrated, with nothing to do, there are also combined rooms where a special headphone presents the translation effect for the blind, being able to enjoy among friends without having to exclude your blind friend.

These contributions are what make a better world every day, it is worth living, is when you value the technology that serves to unite rather than disunite.

New ways in language learning for blind and visually impaired people

Language competence as a European competence is an important factor
for European development. One of the aims of the European Commission is
that all citizens of Europe can understand and speak at least three
languages. Therefore, language competence is not only regarded as a
central element of the understanding among European people, but also
as one of the central qualifications for job mobility and job promotion.
Language learning thus means:

  • According to the European Commission the acquisition of being European
  • (Job) training and mobility
  • Prerequisite for social integration
  • Communication and building up acquaintances via languages
  • Development of personality and strengthening of self-confidence
  • Access to culture and further education

Adequate language learning materials for blind and visually impaired people
are rare, though. It is therefore also difficult to find and to go to
adequate language courses, especially if there are no appropriate training
facilities locally available.
Computer-based, interactive self studying courses would therefore be a solution.
However, these courses are difficult to use for people with visual impairments.
This particularly concerns people who have gone blind in later life since
only a smaller portion of this group learns reading and writing in Braille.
