Spanish Designer Nacho Martí is helping underprivileged people see more clearly. A recent Top Nominee of the Index Awards, Marti’s Stenop correcting glasses bring 20/20 vision to poor people around the world who can’t afford expensive crystal glasses. Glasses are replaced by rows of small holes using the concept of stenopeic vision. Stenop glasses can reduce 80% of myopia, hyperopia and presbyopia. The glasses are plastic made in one single piece and mass produced.


These holes have the effect of reducing the width of the bundle of diverging rays coming from each point of the viewed object. Just central rays reach the retina avoiding focusing errors. They have a very low cost and can be heavily distributed worldwide around kids of poor schools. They are durable and can be done in different colors depending types of skin. Despite the stenopeic glasses were invented long time ago, their production method are slow and as expensive as the crystal glasses. This project optimizes the production method, making the glasses very cheap, light and unbreakable.
