You are in good company Turtle. The Mighty Adam lost use of one eye when he was expanding his chest to break a steel chain that was wrapped around him. And please forgive me this one indulgence... for much the same reason that I ask the woman from Russia who works with me to say "moose and squirrel" every once in a while :hihi:, do you have any pictures of yourself squeezing open a can of spinache? :doh:

They discovered I needed glasses when I was twelve.

 

It destroyed my life.:shrug:

 

Up until then the teachers just thought I was retarded so they left me alone to dream.

 

After Glasses (A.G.) everone began to pick on me and make me work.

They aslo did and IQ test; another reason to hate IQ tests.

 

It was nice to see that trees had individual leaves though.

i actually have extremely good vision.

i don't know exactly what it is, but when the doctors had me read the lines on the vision chart, i remember guessing the 20/20 line flawlessly.

 

is it possible to have better than 20/20 naturally?

 

also, how does the 20/20 system work?

i'm assuming each "20" is for one eye or the other, meaning a person with one eye would have 0/something or something/0.

Actually the fraction is for each eye, i.e one eye can have 20/20 and the other could be 20/40, etc.. When you have 20/20 vision it means that you can read a letter at 20 feet (the top number) that a normal eye can read at 20 feet (the bottom number). If someone has 20/200 vision it means that they can read a letter at 20 feet that a normal eye can read at 200 feet. BTW, the two smallest lines on a standard eye chart are 20/15 and 20/10 so your vision can be better than 20/20 if you can read these lines at 20 feet.

i wonder, now, what my sight really is.

This reminds me of my mother describing how bad her vision is to me.

 

She also used the example of trees.

 

"trees just look like globs of green with a brown stick coming out of the bottom"

hehe yeah that sounds about right! Its like watching the world in HD instead of an old cassette :hihi:

Does anyone read threads anymore, or just respond to them? See post #14. :)

well, we can't be expected to read every single post, can we?

granted that was a silly mistake, not looking into the question a bit further.

I am in fact, blind as a damn bat.

 

My vision is between 20/700 & 20/800.

 

My "ultrathin" lenses are a quarter of an inch thick.

 

Crazy huh? From a distance of eighteen inches, if I take off my glasses while looking at hypography, I can see only a few blue blurs. Nor can I count my finger at arms length.

Yes indeed, 20/15 is better. This vision ratio rating I find is poorly understood by many people, so here's the skinny. The numbers refer to feet, and the first number is your 20 feet & the second number is everyone elses' feet. With your example of 20/15, you can clearly see at 20 feet what "average" people have to move 5 feet closer (15 feet) to see clearly. For my example of 20/80 with a contact on my injured eye, I could see clearly at 20 feet what the average person can see clearly at 80 feet.:)

 

"I see", said the blind carpenter, as he picked up his hammer and saw. :ip:

I get your point

The answer is no

 

That one certainly slipped under the radar

and I have to spread some reputation around before I can give him more!!
