okay so...i randomly came across this question and it's been driving me crazy trying to figure out if i got it right. sorry if it seems like a silly question =P

A person has a 20/40 vision; if an object is placed 20ft away from that person, will he or she be able to see it clearly?

Now i know this means the person if able to see an object at 20ft where a normal person sees it at 40ft. Despite the fact that the person has less than normal vision, he/she is still able to see an object clearly at 20ft away.
right?

Oh and just so i don't violate any thread codes, i was also wondering what were some of your reasons for deciding to pursue a career in optometry? =)

The answer is....

It depends on the size of the object.

Clear enough to pass most DMV "tests". KHE was right, size does matter

Pull out the trig.. lets see the angle subtended by a 20/40 letter....NAH!

I have nightmares that start out that way.
