Forced perception glasses to extend focal point to inifinity

[BurningKrome]

Good morning,

I have heard of "forced perception" glasses used by air force academies which not only make the field of view larger but (more than just reading glasses) make things appear farther away causing a change of focal point that relaxes the eyes bu focusing them at infinity. They were using these to try and prevent eye strain/eye damage in young cadets doing a lot fo reading and computer work during their training.

I have not been able to find reference to these or obtain a pair. I'm wondering if I'm not searching the right terms.

has anyone heard of these?

Many thanks!
Mike

I think those things are called biopters, and it's probably not worth the time.
