What do you need to check in order to have a good all-around vision while driving

Answer 1

To have good all-around vision while driving, you need to check your visual acuity, peripheral vision, and for astigmatism.

Step-by-step explanation:

In order to have a good all-around vision while driving, there are several things you need to check:

1. Visual acuity: This refers to how well you can see objects clearly and sharply. It is tested using a Snellen chart, which displays letters in different sizes. A person with 20/20 vision can see letters that are 5 minutes of an arc at a distance of 20 feet.
2. Peripheral vision: This is your ability to see objects outside of your direct line of sight. It is important for detecting objects or movement in your peripheral vision while driving. The extent of your peripheral vision can be tested by holding your hands out to the side and asking when your fingers are no longer visible without moving your eyes.
3. Astigmatism: This is a condition where the shape of the eye causes blurred or distorted vision. It can be detected using a chart that checks for unevenness in the focus of the eye.
