To give you some idea ......
I met a lady who had been blind from birth but at around age 45 she regained her sight.
Soon after regaining her sight she had the media at her house and one of them asked her if she could see a factory chimney which was in view from her house window, but she did not know what a chimney looked like.
She was alone in her kitchen when she saw something black about 6 inches long on her white kitchen table, she was frightened of it and pointed it out to her husband when he came home, it was a knife which of course she had been using all her life.
For a long time she was terrified of walking downstairs but found it a lot easier if she closed her eyes.
The strangest thing she told me was her first trip along the motorway in a car, it is hard to imagine if you have always been sighted, she wondered why the motorway had barriers across it every few miles and why these barriers lifted out of the way as cars approached them. Have a look next time you drive along a motorway.
All it was was bridges, when you are some distance from them they blend in with the surrounding scenery but as you get closer they rise up above you!
For quite a long time she found life easier to understand when she closed her eyes.
So if you have never been blind you cannot answer your question.
I had an uncle who was blind from birth but when I was a young boy he could sharpen pencils better than any one else!
