Dear Chris, A little about me. I like a person to PUSH me -- for a short period of time. Then I like to go off by myself, and THINK for myself. I relized that...
This is 20/40 requirement to fly and airplane, private pilot. 1st and 2nd class require 20/20. Best, Otis ================== Subpart D - Third-Class Airman...
Dear Friends, I see kids with there nose ON THE BOOK, i.e., 4 inches (-10 diopters). When I say something about it, they say "...who the hell are you to say...
I read somewhere that myopia does not progress past -2.00 Diopters if use of the minus lens is not present. Does this mean even if I do not use the reading...
Alright, I'm reading the wikipedia article on recreational pilot licenses, and they say that the distance vision should be 20/40 at least with or without...
Dear Chris, Setting REASONABLE goals that you have a chance to meet. Sure, everyone wants very, VERY sharp vision and gets VERY upset if the OD does not...
More commentary: The conventional OD will say it is impossible to get out of even the SLIGHTEST amount of negative refractive STATE. I am very close to...
In all your replies, you always either capitalize the word clear, or put it in quotations. By clear, I assume you mean that I can read 1/2 of the letters on...
Dear Chris, Yes there are some word that I use to describe the natural eye's behavior -- to avoid the assumptions of the past. But "Clear" vision I mean that...
Dear Folks, I think the OD has an impossible problem. We want BOTH, very, VERY sharp vision (20/15) instantly -- and also prevention. Guess what. That is...
For me, the worst case scenario is not only this not working at all, but having a negative effect. I am using a +1.5 lens right now. Is there any way, in your...
Dear Chris, To a great extent -- we can only "relate" in terms of what "I" would do if I could read the 20/60 or 20/70 line on the Snellen. If it were me, I...
Alright, all around, me, there are signs that my vision is getting better, and that my vision is still the same. I don't understand. 1 week ago, I was unable...
Dear Second-opinion friends, I receive emails from some people. I ask them to post here so we can all learn from them. Here is the post by Soyew. Otis ...
1 / 0.85 = 1.17647059... Does that mean that I am -1.2 Diopters. Is this consistent with my results on the Snellen. Because if it is, you would not understand...
Before Otis replies, because I do not know what time zone he lives in. I want to advise you that you should see what your score is without squinting. This is...
Dear Chris, My arguments (like Ted Grosvenor) argue that you must START plus-prevention at the threshold, i.e., -1.25 (20/60 to 20/70) and just keep at it. ...
Dear Chris, There is only ONE way to determine your refractive STATE. I can only ESTIMATE it with the information you have given me. What you truly need are...
Dear Second-opinion friends, I truly agree that even plus-prevention is difficult. Some peeople on hearing about it, (with Snellen at 20/50 to 20/70) will...
Dear Chris, At time we will BOTH not understand each other. That is just normal. Here is the value of your 0.85 cm calculation (-1.2 diopters). That tells me...
i have a prescription of -1.5d on right and -0.75d on left eye also the right eye is dimmer and weaker than the left one what should i do to retain the...
BasisPRE.txt From: "Otis Brown" <otisbrown@...> Subject: The basis of the PREVENTIVE second-opinion. Dear Friends, Otis> A discussion by Alex of the...
Dear Sokhoi, I know we tend to rely exclusively on a "prescription", and do not read our own Snellen. There is a profound tendancy to over-prescribe. (Not...
I don't know, I did this last night at 12 o clock so I must not have read the (point of just blur). My vision begins to blur at 70 centimeters. Now with the...
I'm glad Otis started a forum of his own and now no ods like neil and other can come here and bother. anyway. Anyway here's my result again Otis. I took the...
Dear Chris, You can find the power of a plus lens by this method: Take the plus lens out on a sunny day. Hold the lens above a paper. Find the distance where...
Dear Soyew, First some enhancements. 1. It is always good to rely on your Snellen. 2. I would recommend that you get 10 feet away from the monitor, closer...
ok thx Otis. I will get the +1.5 lense. I measured again in the snell i printed out from 20 feet and the results came to be 20/50 right, 20/ 70 left, and 20/50...
Dear Soyew, These discussions are about YOUR empowerment to keep your vision REASONABLY clear through a four year college. 20/50 is not too bad. But the...
