Jane develops a cataract in one eye and gets a vision test. Her test result for that eye is reported as 20/400. What does this mean? Is a rating of 20/20 better or worse?

A visual acuity of 20/400 means that Jane can barely see. What she sees at a 20-foot distance, others with normal vision see at 400 feet. Normal vision is 20/20 vision.
Don't forget to give me a thumbs up!
