Check Your Vision -- Yourself! - otis - 03-02-2008 Dear Friends, Subject: Checking BOTH your Snellen and your refractive STATE -- yourself. We know that the 1914 study (by Bates) was successful. I was told by a majority-opinion OD that this success did not "count" because the kids did not measure their refractive STATE, and their STATE did not change in a positive direction. : Here is the "tool" to make that critical measurement. It is called, variously, a "trial lens kit" or a phoropter. If you a teaching Bates, it would be of value to demonstrate to the person that his Snellen is clearing and his refraction is moving in the correct direction as well. ================= It's basically a phoropter (one of those "which is better, 1 or 2" machines) that you can keep in your purse or jacket pocket. That's 8 plus lenses, 8 minus lenses and a plano lens for each eye, giving you a whopping 289 possible combinations! (Sorry, no cylinder/astigmatism lenses.) <!-- m --><a class="postlink" href="http://www.good-lite.com/i-test.cfm">http://www.good-lite.com/i-test.cfm</a><!-- m --> "Quickly and easily screen vision with the new handheld I-test Phoropter Vision Screener.

Thanks Re: Check Your Vision -- Yourself! - otis - 03-13-2008 Dear Friend, Subject: Astigmatism -- the "scare" word. It is VERY RARE that "astigmatism" will prevent 20/20 vision. Most people will find that a minus-spherical will get you to 20/20. The SLIGHT cyl. will make 20/20 SLIGHTLY Sharper. But is it worth it? I personally HATE the astigmatism 'CORRECTION'. In fact I insist THAT IT NEVER BE GIVEN TO ME (As long has I have 20/40 vision -- pass the DMV). Further, if I am working to clear my Snellen, and get to 20/20, (and some idiot OD insists that I wear GLASSES FOR ASTIGMATISM) then guess what. ??? I will go home, confirm I pass the DMV test, and NEVER FILL THE $300 prescription. Just my second-opinion. Otis |
