What vision is considered legally blind?

If you’re legally blind, your vision is 20/200 or less in your better eye or your field of vision is less than 20 degrees. That means if an object is 200 feet away, you have to stand 20 feet from it in order to see it clearly. But a person with normal vision can stand 200 feet away and see that object perfectly.

Can you drive with 20 70 vision?

Since 20/20 vision would be too restrictive a requirement of drivers, drivers in California are required to have at least 20/40 vision in one eye, with at least 20/70 vision in their worse eye. If your corrected vision in your best eye is worse than 20/200 vision, you cannot drive in California.

What’s the worst eyesight you can have?

20/30 to 20/60, this is considered mild vision loss, or near-normal vision. 20/70 to 20/160, this is considered moderate visual impairment, or moderate low vision. 20/200 or worse, this is considered severe visual impairment, or severe low vision.
