I got my first driver's license at age 16, passing the vision test without glasses. A year later, I would have failed. Indeed, my vision had deteriorated to 70/200 (I couldn't read the first letter at the top of the chart). Fortunately, my corrected vision was 15/15 and the Army was happy for me to enlist. Only thing is that not only couldn't I fly an airplane, I couldn't jump out of one. My uncorrected vision disqualified me from airborne school. Go ahead and laugh. I did. I figured I could find the ground without glasses. Now, here's the punchline... I'm now 76 and I just took a driver's test (old farts in California have to requalify every five years), and I passed the eye test without corrective glasses. The eye doctor calls it second sight. So take heart, brothers and sisters. Although we're out of warranty, some parts can improve (although I wish it were others further south)

Essentially, 20/20 means a person with normal, uncorrected eyesight sees things normally at 20 feet. 20/40 means that a person sees clearly at 20 feet, what normal eyesight sees at 40 feet. 20/400 means that a person sees clearly at 20 feet, what normal eyesight sees at 400. The worse the eyesight, the bigger the second number.
On the other hand, if your eyesight is better than normal, the second number gets smaller. 20/15, 20/10. The person sees clearly at 20 feet, what the normal person, would see clearly at 15 or 10 feet.
