re:Why is ONLY 20/20 Vision so important?

Someone here really messed up the forums by providing some faulty
information. Obviously the people in the know are quite frustrated
it and I'm having trouble comprehending when there's excess
information about metaphors and semantics.

I'll start by trying to answer the actual question.

20/20 was determined when the eye is at it's relaxed state, staring
into the distance that an object should focus to a point on the back
of the eye. This optimal distance was decided at 20 feet. So a
measurement of how clear or unclear a person's visual acuity is now
measured by 20/20. You see at 20 feet what you SHOULD be seeing at
20 feet.

Some people's eyes are capable of seeing things at 20 feet what the
norm should be seeing at 15 feet. So you see better!.. and some
people eyes are not as good because of one reason or another and they
see 20/30.. so you see something sharp at 20 feet when others see it
at 30 feet.

A lens put in front of your eye, being contact lens or eyeglasses will
"BEND" the light accordingly so that the light focuses where it
should. With people who are far sighted, the image focuses past the
point where it should. People who are near sighted, the image
focuses before the point where it should. LENSES, help push this
focus point to where it should be for the best vision possible.

Some people can deal with 20/30 sight because most of their lifestyle
maybe more critical for near vision .. and less for far vision. That
is why some people don't mind it even though it's less than optimal.


Optometrists or Ophthalmologists will try to correct for 20/20 .. if
you can see better than that, then they will correct for it.. but
most people don't need it. Even if you put a higher prescription in
front of someone's eye will not make it sharper for them.. it will
most likely make their eyes more tired by the end of the day.

Hopefully that explains things.

FURTHERMORE, Chris a plus lens... +2.00D does not make things smaller.
A +2.00 lens is basically a magnifying lens and therefore will make
objects look larger.
