Pinhole glasses are based on an ancestral yet extremely effective optical principle: the stenope. Rather than modifying light through corrective lenses, they filter it through a grid of micro-openings. This simple method instantly reduces aberrations and improves focusing precision.
The stenope principle explained simply
Each hole acts as a "channel" that lets through only one well-oriented light ray. Result: fewer stray rays, a sharper image, and easier focusing for your eyes.
Photographic Analogy
It's the same principle as a very closed diaphragm: the smaller the opening, the greater the depth of field and the more precise the image.
Retinal Action
Light reaches the retina directly without being deflected by visual defects (myopia, presbyopia, astigmatism). The eye muscles are naturally reactivated.
What benefits does this technology bring?
Immediate sharpness without lenses
Reduction of screen fatigue
Natural help (myopia, presbyopia)
Training of ciliary muscles
Versatile daily use
Gentle visual training
A natural and progressive approach
The stenope technology works without lenses, without chemical treatment and without electronics. It's a 100% passive method that guides your eyes to better detail perception during moments requiring concentration, precision or visual relaxation (reading, writing, computer work).
Expert opinion
Pinhole glasses do not replace medical correction, but constitute a valuable complementary tool to maintain accommodation flexibility and relieve the visual system over-strained by screens.
