Homework assignment 4.1 judging space in seconds answers
Question:
What if someone you lose his or her central vision?
Answer:
Your central vision is the part of your field of view you need to tell how far away something is and where it is. Most of the time, this area is 30 to 36 degrees wide. What a person can see in the middle is the most important part of what they can see. People can read, drive, and see faces and pictures better because of it. A person with good central vision can clearly see colours, shapes, and details. The macula is part of the retina, which is the lining of the back of the eye. This part is where you can see the whole picture. Central vision is what we can see right in front of us, and peripheral vision is what we can see out of the corner of our eyes without turning our heads.
