<em>stares in awe</em> Dang. </p>
<p>I'm -1.50 and -2.00... and the blindest person I've met (er, discussed prescriptions with) is like -4.50.</p>
<p>My contacts are -9.0 and -9.5. Reading a book without correction would be very difficult, however, without correction I can read the tiniest print on...say...coins or silver and I can see flaws in gemstones others need a loupe to see. (Small consolation, I know :o)</p>
<p>Wowww. Those are prescriptions I didn't even know existed. O__O</p>
<p>Also, your post on the last page is amazingly helpful. If I had seen it a few months earlier when I needed it, I probably wouldn't have had so much trouble. (:</p>
<p>Hmmmm, my mum's vision is -12.5 and -14.5, and she's unfortunately ineligible for surgery.</p>
<p>She's rather helpless without glasses or contacts because of it. :[</p>
<p>Anyone know if there are any genetic predeterminants for eyesight? Or what the primary factors in determining vision are at all? Both her parents have fairly good vision (one's a tad nearsighted), and then I'm here with somewhat bad vision, and I have a brother with good eyes, and then nonimmediate family all over the place. </p>
<p>I wonder if there have been any cases of twins having different vision in lieu of injury and the like (increased UV exposure, etc.)...?</p>
<p>I'm glad you viewed it as helpful. I was afraid it might be TMI. An eye doc once told me "legally blind" is -22.0 (or something like that.)!</p>
<p>I thought legal blindness was 20/200, which translates to -2.5 or so...</p>
<p>^No way. I can see just fine without my glasses and as stated before, I have<br>
-1.25 and -4.25.</p>
<p>
It's -2.5 WITH correction. ie- if your contacts/glasses can only fix your visions down to -2.5, you're legally blind.</p>
<p>
I can also read that tiny stuff! Which is weird.. but nice :]</p>
<p>Ah, apparently 20/200 is the standard when you have the best vision possible (ie you have corrective lenses or glasses or surgery or whatever).</p>
<p>I'm sure most of us here have near "perfect" vision when we're wearing our glasses/contacts.</p>
<p>edit -- ^ lolol, I was time owned</p>
<p>^Hopefully we do when wearing glasses/contacts lol.</p>
<p>I've always wondered.. if someone's vision is bad enough, couldn't they wear contacts AND glasses?
The contacts could get their vision into a more correctable zone, then glasses too. Idk.</p>
<p>^That would suck SO much.</p>
<p>Yep, my mum oftentimes wears both her glasses and contacts simultaneously, although she is capable of functioning fine using just one (for driving and stuff).</p>
<p>I've never been quite sure of why the prescriptions don't just, like, stack, and make it so horribly wrong for her, but whatever.</p>

Huh? meaning.. she's wearing 2 of the same prescription on top of one another? That's weird.. they should "stack" and make her vision messed up though.</p>
