A blind individual is not able to see.
The notion of blind is used to refer to a person who cannot use the sense of sight . Someone who is blind, therefore, is blind : they are not able to see.
Due to some type of anomaly, damage or defect in their vision, the blind cannot correctly perceive the world around them through their eyes. Blindness can be partial or total depending on the degree of disability .
Usually, someone who totally lacks vision or barely manages to perceive light, but cannot appeal to vision to acquire knowledge, is called blind or blind. On the other hand, there are individuals who are partially blind, have low vision, or have limited vision.
Resources for the blind
To minimize the impact of disability, blind people have various tools and resources that facilitate their social integration and interactions. Braille , for example, is a writing and reading system based on the use of raised signs, which are perceived by touch .
Guide dogs , meanwhile, are assistance animals that are specially trained to assist the blind. These dogs provide help when traveling and are trained to bring the blind person what they request.
Generally, to walk on public roads, blind people use a cane that allows them to detect obstacles. The cane is usually white, although there is a color code that allows the user's problem to be identified: red and white for the blind who are also deaf, green or yellow for those who have low vision, etc.
The braille system allows the blind to read and write.
The importance of support from the State
The first point to take into account to create an environment in which blind people can function comfortably is that the majority of them have a normal sense of smell and touch, which is why the Government must ensure that it creates 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 vision considered normal do not know it, there are various plans in cities to help the blind, among which the sound emitters installed in traffic lights and the variations in the tiles on the sidewalks stand out. . The first have the objective of translating into sound the signals that the traffic lights emit through the lights: in this way, it is possible to know if the cars are moving or stopped so that pedestrians can cross.
With respect to the variations in the tiles, these are certain sections on each path where circular or rectangular protuberances can be seen, arranged so that the blind person can decode a message by passing over them. While thanks to sight 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 paying attention to the rules and without running the risk of being hit by a car, without this sense so useful everything becomes more complicated. That is why these messages printed in relief on the floor itself are so important.
Helping blind people
We must point out and highlight that blind people can acquire a very high level of education that allows them to move with great ease through the streets, study a university degree and get a job, among many other things.
This means that we should not consider them to 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 believe they need it, on the other hand, it is a very valuable gesture that they will surely appreciate with a smile.
