Blindness means a high degree of vision loss in seeing much less than is normal or perhaps nothing at all. Most blind people can see something but not very much ,even if they wear glasses. Only about 18% are totally blind.
The World Health Organization (WHO) define blindness as the inability to distinguish fingers (Notice the mention of fingers. That's why Drs. hold up their fingers in front of the patients to check their visual acuity.)at a distance of ten feet(3 meters) or less. So some people who are registered as blind maybe able to see objects 3 meters away but only with great difficulty.Some blind people can see things this far away but only if the object they are observing is directly in front of them. They maybe unable to see the same objects when it is to the side, below or above them. In other words, their visual fields is severely restricted. Because of this, they are likely to bump into the object or trip over it.
Partial sight is a less severe loss of vision. WHO defines it as severe loss of vision and the inability to distinguish fingers at a distance of twenty feet( 6 meters) or less. Very few blind people see nothing at all. A minority can distinguish light from dark;but nothing less.There is some light perception and shadows. Some blind and partially sighted people have no central vision. Others have no side vision. Some see everything as a vague blur . Others see a patchwork of blanks and defined areas. So some people with impaired vision can see enough to read but might have difficulty to cross the road. Most blind pople do not want to be labelled blind. They would rather be classified as people with impaired vision or as visually impaired.
The causes of blindness are : cataracts, Diabetic Retinopathy, Glaucoma from a long history of Diabetes, River Blindness, Trachoma, Macular Degeneration, retinal detachment,and childhood diseases such as corneal scarring, or cataracts from measles or rubella or chickenpox,Vitamin A deficiency, retinopathy of prematurity (sometimes 100% concentration of oxygen from incubators or ventilators for premature babies ) strabismus at birth.and diabetc retinopathy from Juvenile Diabetes. Children with Type I Diabetes sometimes ended up blind. Sometimes, it's genetic. People who became blind suddenly due to loss of eye from trauma(accidents) or damage to the parietal lobe (the sense of sight)of the brain are more likely to have a hard time adjusting. Than those who gradually lose their eyesight due to macular degeneration, glaucoma, diabetes ;as most of these are older people. In these cases their perception of things are stored in the frontal lobe of the brain.
These are myths about blind people:
1) Blind people see nothing.There is some perception of light and dark. and shadows.
2) Blind people have special gifts. Because they are blind, they just tend to listen more carefully, or be more observant; using their other senses of touch,smell ,taste and hearing. They have no sixth sense.
3) Blind people feel other people's faces.
4) All blind people read Braille.
5) All blind people use guide dogs.
6) Blind people can not do normal jobs. Andrea Bocelli, the great opera singer, was born blind and can not read musical notes.

A blind person can see things especially people better than that of a sighted person. A blind person is not distracted by the package, they see with their ears, their hands, their intuitive senses, yes a blind person can see much better than a sighted, in many regards.

I taught a blind student who said he saw colors. But, he was a blind artist. I imagine it is different for every person just like a normal (non-blind) person. But, we all have our handicaps. For example, the fact that you couldn't put your question in a positive format is a handicap.

We're all blind sometimes. We see things that we should not see sometimes, and we don't see what we need to see sometimes. We're also deaf sometimes. What we are, makes our essence, regardless of our sensory inputs.
What good is an eye, if it doesn't see what it needs to see, or if it sees things out of their context?!

If they previously had 'normal' vision, they can describe exactly how they now see.
For those who were never seeing, it is hard for them to describe to us what they are seeing (nothing to compare it to).

No, but I think they "see" a lot more than those with sight do sometimes.
