Conical pinhole glasses are characterized by their conical holes and are the favorite of the majority. Those who have the opportunity to try on different types of pinhole glasses usually choose this type of glasses.
They are not suitable for driving vehicles or for practicing extreme sports.
They are particularly suitable for all vision symptoms for which prescription glasses are usually prescribed: myopia, hyperopia, astigmatism and presbyopia (strained eyesight). Specifically, they are used for all symptoms with graduation between 0 and 5.5 diopters.
Conical holes are smaller near the eye and more open on the outside. These types of holes reduce the phenomenon of diffraction halos present in round or cylindrical holes. This phenomenon is especially annoying when looking at screens and monitors such as those of computers, televisions, tablets and phones. They are of high quality and made in Germany.
