If I were to be blind tomorrow, I would not be able to see my family members, and this would make me very upset. My daily life would be affected in many different ways. For example, I would not be able to do my homework normally. I also would not be able to see this beautiful world and could not do many things.
I can help blind people by guiding them as they travel, since they cannot see the way in front of them. Moreover, I can read books for them, as they can't read by themselves.
There are some special facilities for visually impaired people, such as tactile paths on the pedestrian ways along the streets and electronic audible traffic signals.
I think these facilities are helpful for blind people, and I wish they could live happily.
