Strength of the plus for improvement
« on: November 20, 2014, 01:25:09 PM »

I wonder if the strength of the plus can be too strong that no improvement occurs. I hear from Todd that you should be between D1 und D2 (D1 := edge of focus and D2 := start of blur) and do print pushing.

Well, do you really have to do that? Or is it also okay to just read where it starts to blur or rather so blurry that you still can read the material?

As for me, I wear my +1 diopters when I am sitting in front of the computer (about 80 cm away) and make sure the image is blurry. Then, I work on the computer, but I do not do "active focusing" - if I understand it correctly, (stare and) let the image clear itself.

Kind regards,

You should't confuse active focus with reading with plus.

There is another page in the above site with a digital clock picture. it explains active focus great!

I wasn't able to achieve it the first times but along with CapitalPrince's description I managed to see this phenomenon.
