Hi Alex,
I finally realized that only an OD who understood the science of all natural eyes - would be able to help his own children, AVOID ENTRY, into nearsightedness.
The rest of us, "dumb bunnies" will never understand it, and will "refuse it", if the discussion ever came up.
The advantage for Antonio's children - is that this type of prevention, does not cost anything at all.
Just a parent who will always insist that the child, ALWAYS sit up, and ALWAYS wear a strong plus for near.
The type of intellectual discipline, is severe. I am certain that no one "medical" will ever discuss this subject with you.
But, Alex, you are doing great. I check my own "home Snellen" (brightly lit) for 20/40. Then, I continue to check for 20/20. That is the only right way to do prevention, "on your own".
Keep positing, and keep checking your own Snellen.
I now use a "trial lens kit" on myself. The only scientific was.
Best,
