matagal na yang product na yan back in the 90s pa yata. yung kaibigan ko binigay sa akin yung binili nya at pinagamit ko sa kapatid ko. sabi sa akin di daw puedeng gamitin ng more than 30 minutes dahil sasakit ang ulo kasi nga kino-correct ng salamin yung alignment ng mata.  parang 30 minutes a day daw yata ang gamit nyan.  sabi ng kapatid ko effective daw kasi pag sinusuot nya nababasa nya yung mga letra na di nya mabasa kung hindi nakasuot.

to test pwede gumamit nung ginagamit na air filter sa mga fan ng PC, or make a very small hole with your fingers, pero hindi mo makikita 'yung buong image dahil makikita mo 'yung daliri mo. hehehe.

pinagbawal yan back in the 90s dahil sa petition ng mga taong nasa optical business.  so far, sa pagkakaalam ko hindi na bawal ngayon.  base dun sa claim, nakaka-improve dun sa mga may myopia at proven na nung ibang mga bumili ng product.  kung sa improvement ng vision, maaaring may magandang epekto at kung mapi-fix ang vision, yan ang di ko alam.  gaya ng nasabi ko na-try na ng kapatid ko at sabi may improvement sa vision.

puedeng makita ang effect ng pinhole sa pamamagitan ng fist.  ganito ang ginawa ko: takpan ng kamay ang isang mata, ilapit ang isang mata sa dyaryo/magazine or sa lcd screen, dun sa point na nagiging blurred or hindi na malinaw ang tingin, ilapit sa mata at sumilip dun sa fist na unti-unting binubuksan (pinhole size) hanggang makita ng maayos yung letra. puede rin i-substitute sa fist ang papel na binutasan ng maliit.

Disclaimer:  ang paraan ng pag-testing na binanggit ko ay para lang makita ang pinhole effect.  maaaring sumakit ang mata or ulo nyo lalo na dun sa mga walang diperensya ang mata kung gagawin nyo ng matagal. For demonstration/educational purposes only.

while pinhole lens is ultimate in testing the capacity of the eye, any society need not depend on that alone.  the Concerned Governments can contribute for the good health of those citizens who otherwise can't perhaps afford . by this you are increasing his/her capability to earn one's bread and thereby contribute to GDP even.
 In some African communities they used to make glasses out of two plastic sheets and locking some water in between them before sealing. The quantity of water and size of sheets depend on the power of the lens one needs.
 It was an old story I read  few decades back.  presently ophthalmic glass is cheap enough.
Let us share knowledge, we too gain by the way.

in concept, liniliitan lang nung pinhole 'yung "aperture" kaya umaayos 'yung focus, same thing na nangyayari kapag nag-squint tayo. ang masama dito, 'yung ganung kaliit na butas, ginagawa lang talaga ng mata natin kapag sobang liwanag, kaya posibleng magkaproblema pa lalo. ;D
