Blindness is a cause many are familiar with, as it is the absence of sight and the inability for a person to see. Blindness obviously affects a person’s quality of life in that they are unable to see and react to their lives in a same way as a person with perfect sight. And, since humans are creatures who base their lives and activities on their own sight and reaction to things visually, blindness can be a very difficult issue to overcome.
Blindness can be either genetic or environmentally caused, but either way those with blindness typically need the help of either a sight dog to move them around, or a certified medical professional who can help with daily menial tasks and responsibilities. As such, blindness can be a very difficult and challenging disorder to overcome and still live a full, healthy life.
Blindness can be caused by a whole host of issues, related to everything from genetic disorders that make blindness occur at birth or later in life, to environmental issues where blindness is caused by an acute condition or reason. In genetic disorders, humans can sometimes experience the loss of their sight due to a genetic reason, where they are either born blind, or they lose their sight over time due to diseases like glaucoma and others that affect sight.
With environmental causes, humans can be blinded by various external sources like major accidents and events that cause people to lose their eyes or their sight, or other sources like contaminants and poisons that destroy vision when consumed. Those who experience blindness, even temporary blindness, have to adjust their lives drastically and can find it a significant challenge to do so as they get used to not being able to see to complete their daily tasks.
Those who experience blindness can also experience the obvious stigmas of losing their sight, as it becomes very difficult to live a meaningful and fulfilling life and commit to doing all that one is used to doing when one cannot now see. Blindness can be a difficult disorder to transition into, since sight is such an integral and central part of so many people’s lives.
The symptoms of blindness are simple – it is the inability to see. There can be more complicated factors than that, of course, as with genetic blindness and sight disorders, symptoms of blindness can include the slow decline of sight and vision issues that are coming slowly. But, for the most part, blindness is an acute condition that happens quickly, shows little symptoms before hand, and is typically permanent with people who lose their sight having lost it for the rest of their lives.
