According to WHO, 39 million peoples are estimated as blind worldwide.

What a blind person can see depends a great deal on how much vision they have. 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. However, they may have trouble reading street signs, recognizing faces, or matching colors to each other. If you have low vision, your vision may be unclear or hazy. Some visual deficits cause part of your field of vision to be compromised.You might have a blind spot or a blurry spot in the middle of your field of vision. Or your peripheral vision may be impaired on one or both sides. These issues can involve one or both eyes.
