The notion of blind is used to refer to the person who cannot make use of the sense of the view. Someone who is blind, therefore, is blind: not in a position to see.
Due to some type of anomaly, damage or defect in their sight, the blind cannot correctly perceive the world around them through their eyes. Blindness can be partial or total depending on the degree of disability.
A person who is totally lacking in vision is usually called blind or blind. vision or he can barely perceive the light, but cannot use his vision to gain knowledge. On the other hand, there are individuals who are partially blind, who have low vision or who are visually limited.
To minimize the impact of disability, the blind have various tools and resources that facilitate their social integration and interactions. The braille, for example, it is a writing and reading system based on the use of raised signs, which are perceived by means of the touch.
The guide dogsMeanwhile, they are assistance animals that are specially trained to assist the blind. These dogs they provide help on the move and are trained to bring what they request to the blind.
In general, blind people use a walking stick that allows them to detect obstacles. Usually the cane is white, although there is a code of colors that allows to identify the user’s problem: red and white for the blind who are also deaf, green or yellow for those who have low vision, etc.
The first point to consider when creating a environment in which blind people can cope with comfort is that most of them have the sense of smell and touch in a normal state, for which the Government must make sure to create different infrastructures that allow them to move around the city safely , with advantages and benefits comparable to those of the rest of the citizens.
Although a large part of the people who have a vision considered normal do not know it, there are various plans to help the blind in cities, among which the issuers of sound installed in traffic lights and variations in sidewalk tiles. The former have the objective of translating into sound the signals that the traffic lights emit by means of the lights: in this way, it is possible to know if the cars are moving or stopped so that passersby can cross.
With regard to the variations in the tiles, these are certain sections in each sidewalk where you can see circular or rectangular protrusions, arranged so that the blind person can decode a message when passing over them. While thanks to the view it is not necessary to do anything other than look around to know where the pedestrian path is and in this way cross the street, obeying the rules and without running the risk of being run over by a car, without this sense so useful everything becomes more complicated. This is why these embossed messages on the floor itself are so important.
We must point out and emphasize that blind people can acquire a very high degree of instruction that allows them to move freely through the streets, study a university degree and get a job, among many other things. This means that we should not consider that they need the help of those who have normal vision at all times, since they can develop an almost complete level of self-sufficiency; a hand when we really think they need it, on the other hand, is a very valuable gesture that they will surely appreciate with a smile.
