Hi Phillipp,
Subject: I believe we should be EMPOWERED to make all critical measurement - personally.
Regarding: Meeting the objective REQUIREMENTS for flight - from the FAA.
My strong desire it to avoid wearing a minus lens. To achieve that goal - I must exceed the FAA 3rd and FAA 1st REQUIRMENTS - OBJECTIVELY.
The FAA 3rd is for 20/40 in both eyes. Thus I MUST make this measurement myself - just to be safe. You are exceeding the FAA requirement. It is your option if you wish to wear that -3.0 diopter lens all the time - or no lens at all. You will EXCEED the DMV requirement - since you have 20/25 vision. If you have not yet done so - I would go down (at your convenience) as pass their test - if you wish.
If you wish further Snellen clearing, then I would just continue wearing that plus lens for the close-work you are now doing. Todd did it, and it is very reasonable that you verify your vision yourself - as I do it.
But you might find it interesting (and wise) to order your own -1.0 diopter lens from Zennioptical.com - just to see how that "improves" your Snellen. I am a practical engineer. It would be a good check for you. I suspect you could read the 20/18 line THROUGH a -1.0 diopter lens. In fact, you could wear that "minus" at night - if you wish. But you now know where you stand. I believe in intelligent self-checking - and that is how *I* would do it.
Hi Otis,
I just printed a standard snellen from i-see and in sunlight I was able read every letter on the 20/25 line with a couple of light blinks, it wasn't crystal clear but I saw it. It looks like I am making more progress than I realize, do you think too much convergence is the main culprit for astigmatism?
