In the few cases where blindness results from problems in the brain, the person usually regains some amount of vision due to brain plasticity (i.e. the ability of the brain to rewire itself). Therefore, people who are blind since birth still technically have the ability to experience visual sensations in the brain.
What is a blind person’s imagination like?
The dreams of a person who has been without sight since birth can be just as vivid and imaginative as those of someone with normal vision. They are unique, however, because their dreams are constructed from the non-visual experiences and memories they have collected.
What does a blind person see?
A person with total blindness won’t be able to see anything. But a person with low vision may be able to see not only light, but colors and shapes too.

Can blind people visualize faces by touching them?
Q: Can you recognize who I am by touching my face? A: Probably not. Human brains are wired to process faces visually. Sighted humans tend to process and remember each unique face as a whole entity, rather than as a collection of features.

Can blindness be cured?
While there is no cure for blindness and macular degeneration, scientists have accelerated the process to find a cure by visualizing the inner workings of the eye and its diseases at the cellular level.
Why do blind people wear sunglasses?
A visually impaired person’s eyes are just as vulnerable to UV rays as the eyes of somebody who can see. For legally blind people with some degree of vision, sunglasses might help prevent further vision loss caused by exposure to UV light.

Can a blind person regain their sight?
Recent scientific advances have meant that eyesight can be partially restored to those who previously would have been blind for life. However, scientists have discovered that the rewiring of the senses that occurs in the brains of the long-term blind means that visual restoration may never be complete.
Can blind people drive?
An individual can be completely blind in one eye and not have great sight in the other eye, and still be able to drive. It ensures the eyes are talking to the brain correctly. Then, the candidate has to go through driver’s training just like a new driver with a specialized bioptic driving trainer.
Are humans blind 40 minutes a day?
Humans are blind for about 40 minutes per day because of Saccadic masking—the body’s way of reducing motion blur as objects and eyes move. 20/20 isn’t perfect vision, it’s actually normal vision—it means you can see what an average person sees from 20 feet.
Do dogs dream?
Your dog is fast asleep, when suddenly he starts whimpering, moving his legs or tail, or engaging in some other odd behavior. Scientists think so—in fact, they believe that dogs not only dream as we do, but also that they dream similarly to us, meaning that they replay moments from their day while they’re fast asleep.
